Protecting Students From Fires
By Kenneth Roy
Posted on 2017-09-20
In 2015, the National Fire Protection Association released a revised version of NFPA 45 that included a new chapter titled “Educational and Instructional Laboratory Operations,” which applies to K–12 school laboratories. The new chapter provides fire protection and safety requirements for new and existing educational laboratories doing experiments or demonstrations using hazardous materials.
Most state legislatures will eventually adopt the updated NFPA 45 standard, meaning it is or will become a legal safety standard that school administration and teachers must follow
The Specifics
The first section (12.2: “Instructor Responsibilities”) of the new chapter clearly states that in a demonstration or experiment using hazardous materials, the teacher is required to:
• perform a documented hazard risk assessment,
• provide a safety review to students,
• provide adequate personal protective equipment, and
• place a safety barrier between students and the demonstration or experiment to prevent personal injury.
Furthermore, this section states that laboratory teachers must be trained and knowledgeable in fire safety procedures, emergency plans, lab hazards, appropriate PPE, and conducting an appropriate hazard risk assessment.
The second section (12.3 “Chemical Storage and Handling”) directs teachers to store bulk quantities of chemicals in locked rooms outside the classroom or store portioned amounts for each class session in a locked cabinet inside the lab. The second section also includes the following guidelines:
• Quantities of chemicals should not exceed the pre-laboratory unit quantities specified in local fire or building codes.
• Bulk quantities of chemicals in a prep room should be dispensed outside of the classroom or lab.
• If the lab does not have a prep room, the quantities of chemicals must be kept in locked cabinets before students arrive in the classroom or lab.
• The minimum amount of chemicals needed must be transferred to a smaller, appropriately labeled bottle.
Section 12.3.2 (“Performance of Experiments or Demonstrations”) again requires specific actions on the part of the teacher. For instance:
• Experiments or demonstrations must be performed in a location with access to an exit.
• Experiments or demonstrations involving hazardous quantities of fumes, vapors, particulates, or gases must be operated within a chemical fume hood.
• If it’s not possible to perform the activity in a fume hood, it must be performed behind an impact-resistant plastic or tempered glass safety shield.
• If the activity is performed outside of a fume hood where a shield is not used, students must observe the activity from at least 3 m (10 ft.) away.
• Activities using flammable liquids and open flames must be performed by a knowledgeable instructor.
• Teachers must review the hazards with students, required PPE, and review of emergency procedures.
In the end
NFPA 45 (2015) provides clear direction for science teachers to conduct safer demonstrations or experiments with students. The standard does not, however, prohibit the use of flammable solvents in school laboratories.

Enhancing Google Sheets for the Classroom
By sstuckey
Posted on 2017-09-20
Among the most commonly used tools in the science classroom are those that allow students to collect and manipulate data, including Microsoft Excel, Graphical Analysis, and Google Sheets. This month, we focus on one of the benefits of Google Sheets that sets it apart from similar tools: the add-ons.
If you’re new to add-ons, first look under the add-ons menu in Google Sheets and click “get add-ons.” Once there, you may search for add-ons by category (i.e., Business Tools, Education, Productivity, Social & Communication, and Utilities).
Finding data
Sometimes simply finding data related to a certain scientific content area can be challenging. With the Knoema Data Finder add-on, students can browse a large database of data sets that can be immediately imported into a brand-new Google sheet. This is a great way to get students started on manipulating data.
Representing data
Students may then need to represent their data via equations or statistical representations. g(Math) for Sheets allows students to quickly create and insert complex formulas and graphs that may not be possible with the spreadsheet calculations or formulae included in the Sheets application.
Regular users of Google Forms know that the data collected by the form interface is usually destined for a Google Sheet. Unfortunately, each time a new submission is entered into a Google Sheet that contains Form results, a new row is created, and the formula is removed. The copyDown add-on resolves this issue by automatically applying a formula template to every new row of data for every Form entry. Through copyDown, students can predetermine what data they need to collect as well as the projected calculations that they need to use when they reference submitted data.
Once your students have begun to actively collect data from across a global community, they could represent that data visually by location across the world. Because certain physical properties (e.g., volume) can be different based upon variables such as elevation, temperature, and atmospheric pressure, ask students to connect those variables to the changes in properties to extend their thinking.

The Geocode add-on (sample map, above) can help make this connection. Geocode will automatically create a Google Map with placement markers at every location of submitted data. Just make sure that your students collect the address closest to the position of the collected data. When students scroll over the data points on the map, the content included in each row of data will also appear. The map can even be filtered based on selected columns of data. When this is combined with the calculations done by the copyDown add-on, students should be able to see patterns of data trends across the globe, thus strengthening the computational thinking skills involved with making predictions and forecasting results.
Conclusion
No matter how your students use Google Sheets, add-ons improve the functionality of the tool. There are hundreds of add-ons to help meet the instructional goals of your lessons and to help students achieve and learn.

The Pasco Wireless Light Sensor: See the Light. And Measure it too.
By Martin Horejsi
Posted on 2017-09-18

Within an understated white plastic box is found a dynamic and versatile sensor that effectively measures many forms of light, and gives the science class a peek into how we learn about the universe we live in. Yes, the Pasco Wireless Light Sensor could easily go unnoticed in the science room’s box of technology. It would be understandable to think that this is just another sensor designed to fit into a lineup of other sensors. In fact there really isn’t much on the sensor to indicate just how powerful and versatile this particular sensor really is. There is only one button, the on/off switch. There is a tripod socket, a few words here and there printed on the case, and two apertures, a short black tube for spot measurements, and a flat white circle for ambient measuring. Like I said, uneventful.
But like most amazing gadgets these days, the real show begins when the device is paired with its software. So this little box measuring not much more than 2 x 4 x 7.5 cm actually has the capability to measure:
-Red light
-Green light
-Blue light
-White light
-Illuminance in lux
-Illuminance in lumens per square meter
-PAR (Photosynthetically Active Radiation) in sunlight
-Solar Irradiance in watts per square meter
-Ultra-violet A (UVA)
-Ultra-violet B (UVB)
-Calculate the ultra-violet index (UVI)
Further, the sensor can be so simple in appearance because the data leaves the sensor at the speed of light (in air) traveling over low energy Bluetooth radio waves to any receiving computer, tablet or phone. With a range of about 10m and a easily replaceable CR2032 battery, the Pasco Wireless Light Sensor is a about as perfect a light tool as a teacher can imagine. And speaking of light, it’s pretty much the only thing we get from the universe beyond the earth besides meteorites, solar wind, and sample return space missions, and that list is pretty short.

There is an abundance of concepts to study and light to measure so it follows that there is no shortage of traditional and innovative experiments for any grade level. The Pasco Wireless Light Sensor can easily measure the presence, absence and quantity of a handful of different kinds of light. And with each measurement, there is an ever expanding realm of possibilities, variations, and real-world analogs.


For instance, measuring sunlight is an obvious use of the Pasco Wireless Light Sensor, but wait, there’s more. That same sunlight can be reflected off surfaces, filtered through an endless number materials, fabrics, lotions, and films. UV through clothing can be measured with the fabric dry and wet. Sunscreens can be tested. Sunglasses, auto glass, and windows can be explored. And all of the above can be refined further by applying variables of distance and angles.
A bonus about the size of this sensor is that it happens to be the right size to fit into cell phone cradle or tripod mount. This fact allows the Pasco Wireless Light Sensor to be used effectively in existing and handy stands that can aim the Pasco Wireless Light Sensor as needed.

Color is fair game for the sensor with the Pasco Wireless Light Sensor’s unique ability (especially for the $55 price tag) to measure four colors of light…well three colors and their combination totaling up to white. The quantity of light moving through a filter, say sunglasses, is rarely across a uniform distribution of visible wavelengths. While we often worry about the amount of UV and IR in our sun shades, there are implications for colors. If sunglasses change colors or make them look similar, say green and red, then horizontal traffic lights could be read backwards. Another example is that sunglasses used around water may need to filter much more blue light than sunglasses used for other sports.
The inverse square law can be verified using little more than a meter stick, light source, and of course the Pasco Wireless Light Sensor.

Graphic of the inverse square law. Source: Wikipedia.
Two different apertures allow the Pasco Wireless Light Sensor to measure ambient light and narrower directional light sensor. The ambient sensor measures UVA, UVB, and UV index. The spot sensor measures general light level in several units, as well as relative intensity of red, green and blue light, or all three together as white light.
Bluetooth 4 is the Pasco Wireless Light Sensor communication method with iOS and Android mobile devices, and Mac and PC computers. A list of compatible hardware and software is listed here.
By removing the cables and going wireless, it’s possible to put the sensor in places where it might not be safe to be within the usual meter of wire, such as out in the sun for an hour. The Pasco Wireless Light Sensor can also be set up as a lab station where students log into the sensor to gather their data, then move on to the next station.

The Pasco Wireless Light Sensor is an excellent tool to teach science, and to do science. It’s tiny form factor and huge set of capabilities, but what makes it even more of a go-to solution is that the Pasco Wireless Light Sensor talks to smartphones putting a tremendous amount of science lab into a single pants pocket.

Light is an amazing thing. And even though its wildly prolific in the known universe, it’s Wikipedia entry is still less than half the length of that of Michael Jackson’s entry. Or about the same as an avocado. But whether you think light is a particle, a wave, a combination explained by electromagnetic, or quanta, or likely all (or none) of the above, light is an important aspect of almost every scientific subject. Which, given that line of reasoning, the Pasco Wireless Light Sensor just might be the most universal sensor when learning science.

Health Wise: Be Prepared for Opioid Overdoses
By sstuckey
Posted on 2017-09-18
In light of the national opioid epidemic, schools need to be prepared in case a student overdoses.
Consider:
- In 2016, 4.8% of high school seniors reported using opioids for nonmedical reasons (NIDA 2017c).
- From 2002 to 2015, annual opioid-related deaths grew 2.8-fold to 33,091, says the National Institute on Drug Abuse (NIDA 2017a).
- More than 90 Americans die every day from opioid overdoses (NIDA 2017b).
Opioids is a term that now refers to both synthetic chemicals such as oxycodone (OxyContin, Percodan, Percocet) and hydrocodone (Vicodin, Lortab, Lorcet) as well as drugs derived from opium poppies, such as codeine, morphine, and heroin. Opioids act on brain receptors that then produce dopamine, which causes feelings of euphoria.
The rise of prescription opioid abuse in the United States can be traced to the late 1990s, when pharmaceutical companies “reassured the medical community that patients would not become addicted to prescription opioid pain relievers,” NIDA says (2017b). “This led to widespread misuse of these medications.”
The use of non-prescription opioids, including heroin, often laced with fentanyl, a much more powerful synthetic opioid, have added to the death rate.
A good way to introduce the risk to students is the video Chasing the Dragon (see “On the web”), which features interviews with recovering opioid addicts who started using in high school.
A risk factor for youth is having parents with opioid prescriptions, according to a recent study (McDonald et al. 2017). Among 681 adults with children ages 7 to 17, some 88% reported that they did not lock away their opioids.
High school teachers should know the signs of an opioid overdose, NIDA says (2016a), including:
- pale or clammy face,
- limp body,
- purple or blue lips or fingernails,
- vomiting or gurgling noises,
- cannot be awakened or unable to speak, and
- breathing or heartbeat slows or stops.
Every second counts when someone is overdosing (NIDA 2016a). This is why some high schools now stock the medication naloxone, which can reverse the effects of an opioid overdose. Even non-medically trained people can administer naloxone nasal sprays and auto-injectors (NIDA 2016b).
“Naloxone has the potential to immediately restore breathing to a victim experiencing an opioid overdose,” according to a National Association of School Nurses policy statement recommending that schools have the rescue drug (NASN 2015). “Naloxone saves lives.”
Dr. Adrienne Weiss-Harrison, medical director of a New York school district, recently told a reporter: “We have [naloxone] the same way we have defibrillators and EpiPens” (Harris 2017).

Is Quality PD the Goal of STEM Certification? Here's What the AACT Has to Say
By Guest Blogger
Posted on 2017-09-15
For anyone who isn’t yet familiar with The American Association of Chemistry Teachers (AACT), here’s a bit about who we are. We’re 4,500 members strong, though we’ve only been around for three years. Most of us are teachers, and some are other chemistry professionals. We all care deeply about chemistry education and recognize that teachers of chemistry span all grade levels. We are the first national association by and for teachers of chemistry, and we’re proud to join the company of other science education organizations who share many of our goals.
We define our goals like this:
- We provide the best resources we can to support teachers of chemistry: everything from lesson plans to background reading to student materials to labs and demonstrations. Being a teacher is incredibly demanding and we hope to help our members feel positively rich in resources.
- We bring teachers of chemistry together in a functional network that enables both experienced and less experienced teachers to connect and learn from one another.
- We offer and advocate for targeted, quality professional development for teachers of chemistry. Great professional development empowers teachers with specific skills and tools they need to teach and empower their students.
The STEM Certification Conversation
When the conversation around STEM certification began, we saw that this effort would likely overlap with our interest in quality professional development, because, of course, the value of any certification is in the training, preparation, and experience that underlies it. As advocates for best-in-class professional development, we understand that seeking and renewing certifications are often the driving force behind time and funding being allotted for professional development.
There are certainly many teachers out there who could benefit from training and experience with STEM teaching methods and content. If a certification structure could bring those teachers the experiences and tools they need to better serve their students, then it’s a structure worth considering. Through AACT, we interact with many members who teach other sciences in addition to chemistry, and we appreciate initiatives that support practitioners of multiple disciplines.
In my own teaching career, having taught math and physics along with chemistry, I have gained a real understanding of the relationships among the disciplines. This has benefited my students, as I have been able to reveal those relationships in their classroom experience. The webinars that we have offered that deal with incorporating engineering, solving mathematical problems with intuition in stoichiometry and working without a calculator have all been well received and reflect our members’ interest in multiple disciplines.
Often times, practical know-how and tips for effective teaching are passed on through informal networks and mentorships among teachers. While that is certainly valuable, there is also value in formalizing and clarifying paths for seeking and attaining that knowledge. A clear, formal path can be widely available to all who aim to improve their practice. And, ultimately, the more teachers who benefit from training, mentorships, and so on, the more students those highly-trained teachers will be able to reach.
And aren’t the students what we’re all about in the end? AACT is proud to join our sister associations in pursuing top-quality education for all of our students by advocating for highly supported, well trained, teachers.
Jenelle Ball is the AACT President and Governing Board Chair. She has teaching high school chemistry for over 30 years. She currently teaches chemistry at Chico High School in Chico, CA.

The TI-Innovator Rover: A Vehicle for Coding a Vehicle
By Martin Horejsi
Posted on 2017-09-15

With all the connectivity possible built into the TI-Innovator Hub, it was inevitable that programable motorized peripherals would become available for I-Hub. And that day has arrived. Texas Instruments, the maker of the ubiquitous graphing calculators like the TI-84, has announced the TI-Innovator Rover, a two-wheeled programmable robotic vehicle designed to work directly (hardwired) with the TI-Innovator Hub.
A 360 degree tour of the TI-Innovator Rover is available here, but below are a few more screenshots of the Rover.

The TI-Innovator Hub was detailed on this NSTA Blog back in December. We were impressed with the Hub’s ability to provide feedback and control options in as little as 10 minutes. The coding process of the Hub required an appropriate TI graphing calculator so the coding experience involved a command-line interface rather than the drag-and-drop “language” of many more toy-like coding devices. The current list of comparable calculators includes one model of the 84 (Plus CE), and seven TI-Nspire hardware/software combinations.

According to Peter Balyta, the president of TI Education Technology, “We created Rover to demystify robotics and give students who might be intimidated by programming an easy on-ramp to learn to code. Given the sheer joy we have seen on students’ faces as they learned to code during our testing phase, we are excited to see how Rover will inspire more young minds through an introduction to robotics.”

The TI-Innovator Rover leverages the ubiquitous TI family of graphing calculators and requires a command-line understanding of the coding process. While the learning curve might be steeper for command-line coding, the capabilities are not limited by an available set of drag-and-drop code icons.

The aluminum TI-Innovator Rover with rechargeable battery has two independent drive wheels, a motor shaft encoder, a gyroscope, color sensor, LED lights, and a marker holder that will lay a path for science, art or both at the same time.
TI-Innovator Rover puts STEM into motion. I’m excited to take it for a drive when available.

Ed News: Nebraska’s New Education Standards To Include Climate Change
By Kate Falk
Posted on 2017-09-15

This week in education news, Louisiana to start push to boost student interest in STEM, especially among women; Nebraska approves new science education standards that include climate change; Gallup 2017 Survey of K-12 superintendents highlights challenges facing districts; Next Generation Learning Standards to replace Common Core in New York; coding and the rise of STEAM learning are the trends to watch in K-12 educational technology this year; and California gets waiver from administering old science tests.
State Starting Push For More Science, Math And Engineering Students, Especially Among Women
Louisiana is about to launch a new bid to elevate one of the hottest fields in education, and improve on the dismal number of women in science, technology, engineering and math. The targeted careers will be the topic of an influential panel authorized by the Legislature earlier this year. The goal is to boost student interest in science, technology, engineering and math; align those skills with fast-growing workforce needs and increase the number of women with STEM degrees. Read the article featured in The Advocate.
Nebraska’s New Education Standards To Include Climate Change
The Nebraska State Board of Education has approved new science standards that will see the state’s public schools teaching climate change for the first time. The board voted 6-1 to approve the standards. Read the article by the Associated Press.
Gallup 2017 Survey Of K-12 Superintendents Highlights Challenges Facing Districts
According to the Gallup 2017 Survey of K-12 School District Superintendents, a majority of district leaders report that the greatest challenges facing their schools are budget shortfalls and assisting students whose achievement is impacted by socioeconomic conditions. Additionally, the data finds superintendents in urban or suburban districts are more likely to be engaged than those in their town or rural counterparts, and 66% across all types of districts are seeing fewer new teacher candidates. Read the brief featured in Education DIVE.
‘Common Core’ No More: New York Moves To Adopt Revised Standards With New Name
It’s official: New York has moved to adopt a revised set of learning standards that, among other changes, ditches the politically charged “Common Core” moniker. New York’s Board of Regents voted in committee Monday to accept the Next Generation Learning Standards, capping off a nearly two-year revision process. Read the article featured in Chalkbeat.
Report On Underrepresented STEM Students
A new 68-page report from the Pullias Center for Higher Education at the University of Southern California hopes to address underrepresented students in STEM. The report emphasizes collaboration between existing academic affairs and student affairs programs — which are often separated — as well as specific interventions for struggling students. Read the article featured in Inside Higher Ed.
Coding, Robotics, Makerspaces Poised To Grow In Schools, Report Says
Coding and the rise of STEAM (science, technology, engineering, arts, and math) learning are the trends to watch in K-12 educational technology this year, and schools may be expanding robotics programs and makerspaces, which are physical environments for hands-on learning, predicts a recent report from the New Media Consortium and the Consortium for School Networking.

Why We need To Change The Teacher Vs. Tech Narrative
A recent chart from Bloomberg on the future of artificial intelligence and employment lends evidence to a point I have been making for years: teachers will not be replaced by machines. The chart compares a wide array of professions based on required education levels, average annual wages, and likelihood of automation. Sure enough, elementary and secondary teachers are among the most educated yet least paid professionals; and their likelihood of automation: practically zero. Read the article featured in eSchool News.
California Gets Waiver From Administering Old Science Tests, But Only For Last Year
In a partial victory for California, the U.S. Department of Education has granted the state a retroactive waiver from administering outdated science tests, instead allowing it to give students pilot tests based on new science standards. But the department granted the waiver only for the just completed school year. It made it clear that the waiver doesn’t apply to the current school year, and that if California did the same thing it did last year it could run afoul of the law and risk penalties that could include losing federal funds. Read the article featured in EdSource.
This Law Could Help States Prioritize Science Education
States have a new opportunity to emphasize science education and achievement–once largely ignored during the NCLB era–under new federal policies. ESSA gives states opportunities to create new educational goals and strategies, and states can set clear-cut goals for science achievement and leverage existing policies to meet those goals, according to a new brief from Achieve. The brief takes a look at science education efforts in the 16 states, plus the District of the Columbia, that submitted plans to the U.S. Department of Education during the first round of submissions in May 2017.

Could An APP Help Teachers Recognize Their Own Biases?
A Michigan State University professor has designed an app that helps teachers recognize their implicit biases using data collected from their own classrooms. Assistant professor of teacher education Niral Shah will test the app in 6th through 12th grade math classes in Michigan over the next two years. His colleague, assistant professor of STEM education at San Diego State University, Daniel Reinholz, will test the app in advanced math college classrooms. The two will explore how data generated by the app, coupled with information on students’ own experiences with equity and bias, can help educators make sure they are aren’t unconsciously excluding anyone.

Focus on learning activities
By Mary Bigelow
Posted on 2017-09-14
My fourth-grade students like doing hands-on science activities. How can I get them to focus on the activity rather than socializing? —C., West Virginia
You want students to enjoy the activity and talk with each other, but students need to understand the activity is purposeful and not “free” time. Your preparation and routines will make the difference.
Teachers often assume students know how to work cooperatively. Model and practice the routines for each role and appropriate conversations.
To save time accessing materials, I used numbered trays for each group with necessary materials and a list of the items to help students inventory and return them.
Introduce the activity’s purpose and describe the expected result (e.g., report, table or graph, drawing, model, list of questions, summary, or new ideas to share). Remind students of safety issues and their roles in cooperative learning (e.g., data recorder, equipment manager, clean-up, question-asker).
As you monitor the activity, ask students about what they’re doing and reinforce appropriate behaviors. This is also a time for formative assessments of students’ skills in lab and safety procedures, measurement, and data recording. Deal immediately with individuals or groups who are off-task or engaging in unsafe or distracting behaviors. If things get out of hand, stop the activity and refocus the students back on the activity.
Allow time to summarize the activity and clean up before the end of the class. This gives students time to settle down, focus on what they did, and transition to the next subject or class.
It’s important that students understand a science activity is as much of a learning event as a worksheet or teacher-led discussion—and probably more so.

Off the Deep End: Reflections on my time as a NOAA Teacher at Sea

Sunset/Sunrise over a fjord in Kodiak, Alaska
The Bering Sea is cold, even in June. The water temperature is just above freezing in summer and the spray across the deck of our ship in rough weather can feel so cold it’s startling. Of course, the weather in the Bering can get rough. It’s been 10 years, and I remember it so well. I can still hear the calm sound of the crew’s voices as I looked at ocean swells as tall as buildings towering over us. I thought we would never get through those waves; but for the crew, this was just another work day. Our ship kept plowing on through those storms without complaint; so much steadier than I was. I think of the smell of salt, fish, and diesel fumes from the engine greeting me as I came on deck at 4 A.M. to start my long shift. I remember the rough feel of the harness around my waist which I used to tie myself to the ship while I helped deploy equipment. I recall how grateful I was for that harness as we leaned off the deck and the waves tried in vain to ease me over the side into the waiting water below. These are powerful memories, for me and for my students, because science is not always done in a lab. To understand the world, you must go out into it … not to where it is comfortable or easy, but to where you can find data you need. Sometimes that means going to places like the Bering Sea. That simple truth is something which eludes too many students. They walk away from classrooms and labs thinking that science is an indoor pursuit; the domain of geeks and nerds who forgo a life of adventure, choosing instead to bury themselves in a sunless world of test tubes, lab coats and computers.
We can offer students a more realistic, better-informed perspective. The National Oceanic and Atmospheric Administration’s (NOAA’s) Teacher At Sea Program helps teachers and students understand and participate in the real adventure which science offers. Teachers become part of the science crew on a research ship. I’ve been out with them on the Bering Sea, the Gulf of Alaska and along the northeastern United States. Teachers work alongside the scientists, gathering data, which for me meant processing different species of fish that were brought up in our various nets (you use different kinds of nets depending on what you are trying to catch, and where in the water column you are trying to catch it). We counted, weighed and measured fish. Sometimes we took samples and packed them to go back to the lab. I handled rays, crabs, lobsters, and sea stars of more types than I can describe. These were some of the most beautiful wildlife I have ever seen. I sorted through the strange creatures our nets dragged up from the deep. There was one kind–Monkfish from the northeastern US–which seemed to have two full sets of remarkably sharp teeth, an outer and a set further inside its wide, gaping mouth. I haven’t eaten any Monkfish since. I saw a whale leap with its whole body out of the water and come crashing down three times in a row, and then disappear again into the depths in less time than it took for me to pick up my camera. I saw a long slow sunset in a quiet fjord in Alaska that somehow, unexpectedly, at least for me, gave way to a sunrise and then to a full day. That midsummer night in Alaska was one of the most beautiful sights I have ever seen. I spent several glorious nights working alone on the back deck of a ship in the Gulf of Maine, surrounded by a pod of dolphins that swam circles around our ship all night long. No matter how fast our ship tried to go, those dolphins never seemed to get tired. At least they never complained to me.

Back home, my students got to see all of that, too. They read my blog posts and saw my photos while I was away. In real time, they sent questions to me and the scientists. Whenever my students stumped me (which happened so many times), I had an entire staff of scientists to call on. The interactions where I mediated between the scientists and the students are some of my favorite moments in my nearly three decades as a teacher. One fifth-grade class designed an experiment to test how lobster shells reacted to vinegar – a weak acid – and sent their results to a scientist on our ship. He was studying how lobster shells react to the changes in ocean chemistry (called ocean acidification) which happens when the carbon dioxide we add to our air gets absorbed into sea water.

When you work with one superb program in a government agency, and see the extraordinary benefits to the local community of that participation, it can lead to participation in other programs which they offer. I’ve been a Peer Leader in NOAA’s excellent Climate Stewards Education Program for the last several years. That program offers teachers advanced training and certification on climate science directly from scientists working in the field, and has been an invaluable resource in my work. I also had the opportunity to work with NOAA’s Teacher on the Estuary training program. I began attending NSTA’s national conference as part of my participation with NOAA. I then presented as part of NOAA’s NSTA workshops and later wrote my own proposals for presentations and began presenting those materials at NSTA. For me, participating in NOAA’s programs has been transformative. You should do it, too.

Commentary: Reasoning Versus Post-truth
By sstuckey
Posted on 2017-09-14

Nicolaus Copernicus’s heliocentric model of the universe was reasoned from evidence but conflicted with popular beliefs of the day.
The Oxford Dictionaries word of the year for 2016 was post-truth, defined as “denoting circumstances in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief.” Science is not immune to appeals to emotion and belief rather than fact.
To help us challenge the drift toward post-truth, the history of science reminds us of the qualities that support all the practices of science, including evidence-based reasoning.
The evolution of evidence-based reasoning
Empirical evidence and reasoning have not always been at the heart of the scientific enterprise. Evidence-based reasoning evolved in response to beliefs that were increasingly untenable to early natural philosophers. In the early 1600s, the first scientific academies were established in part to uphold the primacy of experiment in questions about the natural world. Such a stance was counter to scholasticism, the dominant medieval method of learning “rooted in Aristotle and endorsed by the Church, [which] involved certain beliefs about the celestial realm … as well as the terrestrial realm of Earth” (Carlin 2009, p. 5).
Synthesizing Christianity and Aristotelian thought, scholasticism viewed the universe as simultaneously religious and physical. The scholastic reaction to the heliocentrism put forth in the 1543 publication of De revolutionibus orbium coelestium is entirely understandable: Copernicus challenged not just a “scientific” model of the universe but also a view of man’s place in creation.
The difficulty that philosopher and scientist Francis Bacon had with deductive scholasticism was that it was static, not permitting new knowledge to develop. By introducing and promoting induction as a method for studying nature, Bacon profoundly influenced the course of scientific inquiry: “Under the leadership of Francis Bacon, most of the empiricists would come to believe that a natural philosophy rooted in experimentation, as opposed to the purely theoretical … method employed by scholastics, was crucial to understanding nature’s ways” (Carlin 2009, p. 11, emphasis in original).
Empiricism challenged scholasticism by relying on rigorous observation, experience, and, increasingly, the belief that “all natural change can be explained in terms of the mathematical properties of matter in accordance with laws of nature” (Carlin 2009, p. 11). One of the centers of this intellectual struggle was Florence.
The Accademia del Cimento
Artists and natural philosophers, supported by the House of Medici, helped make Florence, capital of the Grand Duchy of Tuscany, a cultural, political, and economic powerhouse. After Galileo died in 1642, both Grand Duke Ferdinano II and his brother Prince (later Cardinal) Leopoldo recognized the political value of continuing to support Galileo’s experimental practices.
This led to Leopoldo’s creation of the scientific Accademia del Cimento in 1657. In 1664, the Accademician Francesco Redi recorded that Leopoldo was interested in science “not for vain or idle diversion, but rather to find in things the naked, pure, genuine truth” (Feingold 2009, p. 231). Leopoldo’s commitment to experimentation was captured in the Accademia’s motto: Provando e riprovando (Test and Test Again).
The Accademia was charged with the standardization of measures and scientific methods and the development of standard scientific instrumentation. The main experimental interests centered on thermometry, chemistry, medicine, and pneumatics. Experimental work was carried out in Florence, Livorno, Pisa, and Pistoia.
Leading Accademicians included the physicist and mathematician Viviani; the physiologist, physicist, and mathematician Borelli; and the physician, biologist, and poet Francesco Redi, whose seminal 1668 work, Esperienze Intorno alla Generazione degl’Insetti (Experiments on the Generation of Insects), marked the beginning of the end of abiogenesis.
Experimentation and evidence
The Accademicians regarded experimentation as central to the practice of science, directly in contrast to both Aristotle and the Church. The preface to the Accademia’s famous Saggi di naturali esperienze (Essays on Natural Experiments) (the “Saggi”), published in 1667, argued that experimentation was central to understanding the physical world:
… there is nothing better to turn to than our faith in experiment. As one may take a heap of loose and unset jewels and seek to put them back one after another into their setting, so experiment, fitting effects to causes and causes to effects… performs enough so that by trial and error it sometimes succeeds in hitting the target.
The preface was also clear on the need to reason from evidence, recognizing that it was necessary at times to return to prior experimentation and reasoning:
Besides trying new experiments, it is not less useful to search among those already made, in case any might be found that might in any way have counterfeited the face of truth.
The Saggi emphasized the importance of mathematical reasoning in descriptions of experimental work. In doing so, the Accademicians worked to remove any reference to philosophy or mythological cosmology from experimental science and so establish the authority of experimentation in questions about the natural world. This was an overt challenge to the prevailing scholastic view of the natural world.
To reason from evidence is not simple, as it opens the evidence to speculation and argumentation. The Accademicians often struggled to reconcile their interpretations of the experimental data. Leopoldo, the Accademia’s patron, actively engaged in these scientific conversations, challenging, and being challenged by, the other Accademicians to the extent that some “thought they could speak freely” with him (Feingold 2009, p. 232). A particular point of contention within the Accademia was the range of views about the relationship between experimentation and the still powerful approach of Aristotle. These competing views stimulated “sharp confrontation, often resorting to insults” among the Accademicians (Beretta 2002, p. 12).
The authority of reason
Leopoldo ordered that individual contributions not be credited in the Saggi so that readers would be convinced by the evidence presented rather than the reputation of the author. Also, the Accademicians desired to “underline the impersonal nature of the scientific enterprise” (Beretta 2000, p. 142). In asserting the primacy of the experiment and reason over the hegemony of scholasticism, the publication of the Saggi was a landmark in the history of science.
Understanding modern science
The work of the Accademia set out the need for replicable tests, the control of variables, and the standardization of measurement and instrumentation. It also demonstrated that modern science is more than just knowledge; science is a human endeavor based on curiosity about the natural world, observation, argument, creativity, and reason. These qualities are found in the Next Generation Science Standards (NGSS Lead States 2013). As science teachers, we must model, teach, and practice these qualities if we are to engage our students with the need for evidence and reasoned argument.
The Accademicians struggled to establish the ascendancy of evidence and argument over reputation. While “sharp confrontation, often resorting to insults” may be a bit harsh for our classrooms, scientific discourse requires an environment in which ideas can be put forward, challenged, refined, and challenged further. This practice also includes a willingness to return to experiment and evidence to develop explanations that more closely reflect our current understandings. Such an environment must be crafted by those in authority within the classroom and not left to chance.
Leopoldo promoted and funded the Accademia, and as a powerful Medici, could have demanded deference. That his scientific reasoning was open to challenge serves as an important example. As educators, our challenge is to use our authority in the classroom to engage, alongside our students and as learners ourselves, with all of the practices of science, and thus build trust in those practices.
Conclusion
Post-truth relies on the distrust of both the sources and value of information. This loss of trust in institutions and academic disciplines—including science—along with the wide availability of misinformation that conforms to what people want to hear, diminishes expertise and learning. Drawing from history, we can give students the tools and attitudes needed to challenge those who would devalue reason so that reasoned decision-making can triumph. Just as the Accademicians challenged scholasticism and eventually prevailed, so must we challenge the very idea of post-truth.
