The school year is well under way. But before students enter science labs, they must turn in a safety acknowledgment form.

After completing introductory safety training, as noted in NSTA’s Duty of Care (NSTA 2014), review and have students and their parent or guardian sign a safety acknowledgement form (see Resource), stating safety practices and protocols. In addition, test students on the safety training before they begin any lab work.

It’s important to know the difference between a safety acknowledgement form and a safety contract. Generally, a teenager can enter into a legal contract at age 18, so younger students should only be asked to sign a safety acknowledgment form. By signing a safety acknowledgment form, students confirm that they have been informed that the lab can be an unsafe place, and that they have agreed to follow safety procedures and protocols.

The science teacher needs to keep the original copy of the forms on file for the duration of the class. The statute of limitations for negligence in most states is three years from the date of harm. If there is an accident in the classroom or lab, the teacher should compile safety information records, including the acknowledgement form and accident report, and provide copies of the records to his or her school district. In the event of an accident, these documents should be kept until the statute of limitations run out. In some rare cases, when parents refuse to sign the safety acknowledgment form, teachers need to date, sign, and note the fact that the parent refused to sign the form.

Once the lab investigations are under way, science teachers also have the responsibility to:

1. Inspect for safety before, during, and at the close of activities, and monitor student behavior and equipment to help foster a safer learning environment.

2. Enforce appropriate safety behavior and apply a well-defined progressive disciplinary policy, which involves a progression of steps, starting with a verbal warning and escalating to removal from class.

3. Follow-up on maintenance to ensure engineering controls and personal protective equipment are operational and meet the manufacturers’ standards. If the ventilation cap on a chemical splash goggle has been removed, for instance, take the goggle out of operation.

As with all sports, skateboarding involves a lot of intriguing physics. I’ve marveled at the maneuvers of skilled skateboarder Alex Hewitt (my grandson). When traveling along a horizontal surface, Alex crouches and then springs upward with his skateboard to continue horizontal motion along a nearly half-meter-high elevated surface (above).

He could easily do the same while wearing roller skates, which would be no big deal because the roller skates would be attached to his feet. But in no way is his skateboard so attached. So how does the skateboard manage to follow him along his upward trajectory? Furthermore, by what means does the board gain gravitational potential energy with no applied upward force and no apparent loss in kinetic energy?

This amazing feat bothered me because it seemed to contradict the laws of physics. I then watched a slow-motion video of Alex to learn how he does it.

Figure 1. The downward force on the tail of the board rotates the board upward.

Exerting a torque about the axis of the rear wheels
The leap that Alex executes is called an ollie, a blend of the physics of linear and rotational motion. While heading for the elevated surface, he crouches and springs directly upward while exerting a downward force on the tail of the board that produces a torque about the rear wheels. (Torque = force × distance about a rotational axis.) This quick downward snap of the tail, with or without its making contact with the ground, causes the board to rotate upward into the air (Figure 1).

The same thing happens when you give a sharp tap to the rounded end of a spoon lying on a table. The spoon flips up into the air, just as Alex’s skateboard does. The center of masses of both the spoon and board are raised by this snap-and-flip action.

Figure 2. The downward force by the front foot on the nose of the board counters the first rotation produced by the back foot.

Exerting a second torque about the board’s center of mass
Controlling lift goes further. While the airborne board rotates upward, Alex slides his forward foot toward the nose of the board and produces a second torque, in the opposite direction (Figure 2).

This second torque raises the tail, puts the board in contact with the back foot, and levels the board before it meets the elevated surface (Figure 3, below). So we see the results of two torques, one that flips the board upward and one that levels it off. Skillfully executed, this sequence enables Alex and his skateboard to meet the elevated surface.

Energy conservation
The kinetic energy of Alex and his skateboard before and after the ollie is practically the same. Yet he and the board have gained substantial gravitational potential energy as the board rides atop the elevated surface. Does the ollie maneuver violate the conservation of energy? No, it does not. Here’s why: First, the energy that propels Alex himself is straightforward. By crouching and leaping, he converts bodily chemical energy into mechanical energy just as if he had jumped up from rest.

But what about the board? From where does it get the energy to move upward and follow Alex? The answer involves the work-energy

Figure 3. The counter rotation levels the board for a horizontal landing.

principle of mechanics (work done = change in energy). For straight-line motion, work = force × distance moved. For rotational motion, work = torque × angle moved.

Alex does work on the board when he produces a torque that flips it into projectile motion. As with all projectiles, acquired kinetic energy converts to gravitational potential energy.

Another explanation, the simplest, bypasses rotational mechanics and energy conservation. The force that Alex exerts on the tail of the board as he jams downward on it is significantly greater than both his weight and that of the board. In action-reaction fashion, this downward push produces an upward normal force (the perpendicular support force) that is also greater than the combined weights of

Figure 4. The normal force N propels Alex and the board into projectile motion.

Alex and the board (Figure 4). This increased normal force launches both Alex and the board into projectile motion.

One of the beauties of physics is that puzzles often have more than one explanation.

Hooray for the conservation of energy and for skateboarding in general. ■

“At what age can a child begin science learning?” asked one participant at an early childhood education workshop on investigating the properties of water in a fun, scientific way using observation, documentation and reflecting on that work. The group answered the question, “As infants,” “My babies do,” and “At any age,” just as I put this photograph on the screen:

The educators work in diverse programs, from Head Start to Montessori to their own child care programs in their own homes. About half of the Early Childhood Care Education workforce cares for and teaches children outside of formal child care centers and preschools (NAS 2012 pg 114). I began my career in early childhood education as one of the educators who care for children in our homes, a family child care provider. At this workshop most of the educators were immigrants and their education was a varied as the countries of their birth, and we came together in our shared passion for understanding how young children learn. Everyone participated, making and playing with small drops of water (thank you Young Scientist series!); pouring, scooping and splashing water; using tubes, funnels and frames to create systems to move water; and discovering how cups with holes in various positions can also create systems (thank you UNI’s CEESTEM!). We talked about safety first, liquid/solid, noticed the “stickiness” of water, explored displacement and the force of moving water. It was fun! I’d like to claim that it was my skill as a presenter that kept the group engaged but it was their curiosity and desire to continually improve so they can be even better teachers for the children in their care.

As we worked, the group discussed their ideas about science concepts and shared how to help the parents of the children they care for understand how children learn through experiences. As always, I appreciate the generosity of this education community—they listen to each other, ask questions to get the most out of the session, share materials and their expertise, and help clean up at the end.

In the September issue of The Science Teacher, we wrote about the new standards for digital skills established by the International Society for Technology in Education (ISTE). Now, let’s look at how the standards can be applied to science content.

This month, we discuss the Empowered Learner standard, which requires that “students leverage technology to take an active role in choosing, achieving, and demonstrating competency in their learning goals, informed by the learning sciences.” To accomplish this standard, students should meet these four performance indicators:

• Engage in personal goal setting that includes reflection,
• Develop the ability to build a network to support their learning,
• Use technology to receive feedback in different forms, and
• Understand and troubleshoot technology.

Meeting the performance indicators

Goal-setting is a critical part of the learning process. SMART Goal templates, often used in business, can ensure that students are developing personal goals. Students can use blogs (e.g., WordPress), journaling tools (e.g., Evernote), or even “media diaries” (e.g., Fotobabble and Photo 365) to share their thoughts or reflect on their goal achievement and learning. Changes to thoughts or understanding can also be seen through the evolution of student writing via track changes in Microsoft Word or revision history in Google Docs.

To become an empowered learner, students must build a network to enhance their learning. Twitter can be a powerful tool to build and grow learning spheres. Point your students in the right direction by creating a class account used to follow science-related people and groups. When starting your Twitter network, consider following NASA (@nasa), Earth Science Week (@earthsciweek), NSF Earth Science
(@NSF_EAR), and Neil DeGrasse Tyson (@neiltyson). After establishing the classroom’s virtual networks, allow students to customize their learning environment with flexible and moveable classroom arrangements, such as furniture, which foster a collaborative and “networked” classroom.

Empowered learners should be familiar with the feedback many technology tools inherently provide. It is important that students recognize the value of “adaptive learning tools,” such as Knewton, as a means to grow and develop in any content area. It is equally important that students draw upon technology tools’ interaction and peer feedback capabilities found in resources such as Google Docs, VoiceThread, or Padlet. With those commenting tools, students can share thoughts about the instruction, conclusions drawn from a lab investigation, or predictions about a future event, while quickly receiving comments from other students, teachers, or experts in the field. No matter the tool, however, gathering peer feedback develops the communication skills necessary for the requirements of this standard.

None of the performance indicators are possible without a basic understanding of how technology tools work, so that technology never serves as a barrier or distraction to learning. To illustrate the supportive nature of technology and understanding how the tools fundamentally work, use Chrome Extensions with students. Students must understand that the Chrome browser is a power productivity tool that can be enhanced by Extensions and Apps to improve learning, perform tasks, and enhance their work. As an example, head over to the Chrome Web Store and search for the “periodic table.” You will quickly find both apps and extensions that can be valuable for students.

Conclusion
The Empowered Learner standard allows students to develop an independence and responsibility for their learning. As students mature and advance their skills in this area, they will be ready to tackle the rest of the standards. In the next issue, we will examine the role that digital citizenship plays and the responsibility that all educators have to foster it in their classrooms.

On Oct. 12 the U.S Department of Education released final rules that will require states to establish an accountability system for their teacher preparation programs that includes how graduates perform as teachers based on their students’ academic success. Low performing programs that don’t measure up will risk the loss of federal TEACH grants.

The final regulations are designed “to provide transparency around the effectiveness of all preparation programs” (traditional, alternative routes, and distance) and will require states to report annually – at the program level – on the following measures:

• Placement and retention rates of graduates in their first three years of teaching, including placement and retention in high-need schools;
• Feedback from graduates and their employers on the effectiveness of program preparation;
• Student learning outcomes measured by novice teachers’ student growth, teacher evaluation results, and/or another state-determined measure that is relevant to students’ outcomes, including academic performance, and meaningfully differentiates amongst teachers; and
• Other program characteristics, including assurances that the program has specialized accreditation or graduates candidates with content and pedagogical knowledge, and quality clinical preparation, who have met rigorous exit requirements.

States have the flexibility to report on additional measures, and how to weigh all outcome measures, but must use at least three levels of performance indicators (effective, at-risk, and low-performing).

States (and stakeholders) must design their reporting system in 2016-17 academic year. They may choose to use 2017-18 as a pilot year and the system must be fully implemented in 2018-19. The first year for which any program might lose TEACH grant eligibility will be 2021-2022.

They must engage with stakeholders to develop and/or improve their teacher preparation systems to identify effective and low-performing programs and provide technical assistance to any program rated as low-performing.

The new regulations—which took about five years start to finish –largely reflect the administration’s original proposal from 2014. These regulations, especially language that ties preparation programs to student learning outcomes, faced (and continues to face) huge opposition from many groups.  (In their press release, the Department flagged a “notable” change in the final rule was providing states with “increased flexibility in how they measure student learning outcomes and weigh various components of their systems, specifically by allowing states to determine their own student learning outcome measures that are relevant, but not necessarily directly tied, to student achievement or educator evaluation results.”)

In a statement American Association for Colleges of Teacher Education President Sharon Robinson says “ At first glance, it appears that the voices of the profession may have been heard, as the new rule includes some adjustments that reflect concerns raised during the public comment periods. While the main oversight structure remains in place as described in the initial notice of proposed rulemaking, the final rule gives states more leeway in determining some aspects of the accountability system. Therefore, as it is with the implementation of the Every Student Succeeds Act, the advocacy of AACTE members at the state level remains critical.”

The American Association of State Colleges and Universities statement notes “AASCU has long opposed a federally mandated state-rating structure for programmatic offerings of colleges and universities.  It sets a dangerous precedent for political intervention in academic policy. We are disappointed that the Department did not delay the regulations that address teacher education. We urged them to wait until after Congress, state colleges and universities, and other key stakeholders could work together, through the reauthorization process of the Higher Education Act (HEA), to address the underlying policies and practices around preparing America’s teachers.  Additionally we disagree with the department’s view that the regulation will have only a minimal affect on costs for our institutions.”

The rules were roundly condemned by union leaders:  American Federation of Teachers President Randi Weingarten said it was “ludicrous to propose evaluating teacher preparation programs based on the performance of the students taught by a program’s graduates . . . Instead of designing a system to support and improve teacher prep programs, the regulations build on the now-rejected high-stakes testing system established under NCLB and greatly expanded under this administration’s Race to the Top and waiver programs. It’s stunning that the department would evaluate teaching colleges based on the academic performance of the students of their graduates when ESSA—enacted by large bipartisan majorities in both the House and Senate last December—prohibited the department from requiring school districts to do that kind of teacher evaluation.” 

National Education Association President Lily Eskelsen García says the regulations “takes us back to the failed No Child Left Behind days . . . Using P-12 student test data to measure the quality of teacher preparation ignores whether new teachers are more likely to work in schools with limited resources for textbooks, technology, engaging learning experiences such as connections to community projects. It ignores potentially crucial differences between the quality of mentoring available in one school but not in another, class sizes and class loads beginning teachers may encounter, and the availability of supplemental services to ensure that each student can come to class ready to learn.”

Congressional leaders were equally displeased with the final rules. House Education and Workforce Chairman John Kline said in a statement “While more needs to be done to ensure teachers are prepared for the classroom, the department is taking a one-size-fits-all approach that will lead to unintended consequences. It will be impossible to effectively implement this vast regulatory scheme, and it may lead to fewer teachers serving some our nation’s most vulnerable children. And to add insult to injury, this new rule does not reflect the bipartisan consensus that was reached in our recent efforts to improve K-12 education. This is an issue policymakers should discuss and resolve through broader reforms of the Higher Education Act, not through the unilateral actions of the Department of Education.

Senate education committee Chairman Lamar Alexander (R-Tenn.) noted “Today’s regulation appears to violate the Higher Education Act, which specifically says that states—not bureaucrats at a distant department in Washington—are responsible for evaluating whether a college’s program gives teachers the skills they need for the classroom. The regulation also effectively mandates teacher evaluations and forces states to focus on students’ test scores in a way that Congress explicitly rejected just months ago when we fixed No Child Left Behind and its unworkable National School Board approach.” 

Several education reform groups, including Education Reform Now, Chiefs for Change, National Center for Teacher Quality support and praised the Department of Education for the new rules.

The Four Strands of Science Learning and the Next Generation Science Standards from Science Scope is an informative article for teachers of any grade level.

Science Scope – Earth Science Activities

According to the editor, “Today’s students will become adults tasked with making decisions about environmental issues that will require a solid understanding of the Earth sciences.” And the Earth sciences are so interesting, too! If I were designing curriculum, Earth science would be the capstone course, integrating concepts from physics, chemistry, and the life sciences.

• The 5E lesson in Earth History Theories: Relative Age Dating Lab With Additions for Mining and Mineral Exploration integrates stratigraphy, age-dating, fossil and ore deposits as students make and use models of rock layers
• Exploring Lunar and Solar Eclipses Via a 3-D Modeling Design Task has a lesson idea to help students understand the phenomenon and dispel misconceptions.
• Teacher’s Toolkit: Puzzle Boxes for 3-D Learning About Natural Hazards describes how an observation activity can be adapted for in-depth discussions.
• Classic Lessons 2.0: Using Multiple Representations to Teach Science uses the example of moon phases to describe how to guide students through a sequence of concrete to abstract representations.
• Citizen Science: Clouds in the Classroom describes a project that’s been around for a while, gathering data from student observations—authentic science. And students investigate clouds in the classroom with the 5E lesson in Disequilibrium: Forming Clouds in the Classroom
• Earth science has many phenomena to explore, using the ideas in Teacher to Teacher: Phenomenal Engagement.
• Listserv Roundup: Finding and Saving Earth Science Resources lists additional resources on related topics.
• Science for All: Literacy Engagement and Its Role in the Science Classroom has resources for finding reading material appropriate for various student reading and interest levels.
• Scope on the Skies: Connected Computing describes how classrooms can contribute to authentic projects.

Articles that describe lessons include a helpful sidebar documenting the big idea, essential pre-knowledge, time, and cost.

For more on the content that provides a context for these projects and strategies see the SciLinks topics Clouds, Earthquakes, Eclipses, Layers of the Earth, Minerals and Rocks, Moon Phases, Natural Hazards and Disasters, Stratigraphy, Water Cycle.

The Science Teacher – Adding Art to STEM

The featured articles in this issue focus on the overlap and integration of science and the arts (STEAM, as some call it). As the editor notes, “…science and the arts both spring from the same deep well of human creativity and imagination.”

• The Art-Science Connection has examples of the artwork create by students to communicate the results of their research and demonstrate their learning.
• The National Park Service turns 100 this year. Science and Art in the National Parks traces the history of the arts in the Parks and has suggestions for using them as inspiration for art and writing activities and a context for the sciences, such as geology. (Is it time to bring back the Federal Art Project from the 1930s?)
• Getting an A in STEM shows how chemistry and art can “cross-pollinate” using the concepts of chromotography, molecular structure, the Periodic Table,
• Sculpting the Barnyard Gene Pool illustrates how creativity doesn’t have to involve music or drawing. The interdisciplinary project focuses on engineering challenges and genetics. Likewise, designing investigations, as described in Measuring Metabolism, involves creativity and problem-solving.
• It may not be in the same arts league as dancing, but as Focus on Physics: Skateboard Physics shows, sports use physics creatively.
• Career of the Month: Acoustical Consultant describes how to use physics to create spaces for the performing arts.

For more on the content that provides a context for these projects and strategies see the SciLinks topics Acoustics, Cell Division, Chromatography, DNA, Genetics, Heredity, Homeostasis,  Microscopes, Molecular Shapes, Periodic Table, Photosynthesis, U. S. National Parks.

Science and Children – Natural Hazards

The featured articles this month describe how to tap into children’s interest in these phenomena, including the causes and how to protect ourselves. The lessons described in the articles include connections with the NGSS.

• Storm Warning challenges students to design, build, and structures that can withstand natural disasters.
• On a similar topic, What’s Shaking?! examines earthquakes through technology-based simulations. Students then design an earthquake-proof city.
• Science and social studies are Complementing Curricula in an integrated lesson on environmental science topics.
• Using direct and indirect evidence, students can observe, investigate, and analyze In Our Neighborhood: Who’s Been Here?
• The Early Years: Navigating Natural Disasters describes how children can be year-long weather watchers and includes a lesson on modeling how water moves and can be contained.
• The Poetry of Science: Hurricanes includes a poem to read aloud and discussion questions.
• Teaching Through Trade Books: Forecasting Hazardous Conditions has resources and 5E lessons for students learning about severe storms and hurricanes, including their causes and how to survive them.
• Science 101: What Causes Severe Thunderstorms and Tornadoes? has background information for teachers and activities on these topics.

The Go!Temp probe, made and sold by “Vernier Software and Technology,” collects real-time temperate data, making it applicable in a number of different fields, e.g., biology, chemistry, physics, earth science , etc.

The Go!Temp is easily compatible with a computer flash drive without the need for an interface. Before connecting the Go!Temp to the computer, download either “Logger Lite” or “Logger Pro” from the Vernier website (link below). Logger Lite is available for free download. Logger Pro has more capabilities, including the use of XY graphs, log graphs, or manual data entry, but will cost $249. Once either Logger Lite or Logger Pro is downloaded and the Go!Temp is connected to the computer, the computer will automatically detect the Go!Temp and it is ready for use.

Logger Lite: http://www.vernier.com/products/software/logger-lite/

Logger Pro: http://www.vernier.com/products/software/lp/

To use the Go!Temp, hold the device by the plastic end and place the metal portion where you would like it to take the temperature measurement. Simply press the green “Collect” button at the top of the screen to begin data collection. Once the data is collected, you will be able to examine the data in a number of ways to meet your research goals.

Here is a video of the device being used:

Calculate statistics and speculate

Logger Lite has a built-in statistics calculator. Under analyze, if you select Statistics, students will have the mean and median temperature, as well as the minimum and maximum temperatures. Therefore, students can analyze the range of temperatures over time and can ask a variety of questions:

• When was there less variation in the reading? What reason(s) can you suggest for steadier readings at this time?
• When did the low and high temperatures occur? What factors contributed to these readings?
• From differences you see in the temperature readings during the day, what can you infer about the amount of sunlight on the thermometer? Provide observations and reasonings to support your inferences.
• Does the temperature in different places affect the duration of temperature change? If so, how does it?

The possibilities for experimental applications in the science classroom are endless. Students will be able to conduct a wide variety of experiments, such as investigating the thermal reaction between baking soda and vinegar in the chemistry classroom, monitor the energy given off by food as it burns during an experiment in the biology classroom, or to test Thermodynamics in the physics classroom. Clearly, the Go!Temp Thermometer is relevant in a number of different fields of study and can be used with elementary and high school students.

Conclusion

Having students collect temperature data through technology-based inquiry is commensurate with tenets of the National Science Standards. Undoubtedly, using the Go!Temp Probe can help teachers show students how to use the latest technology in an inquiry setting to gather data. In addition, the interactive graphs that can be generated by Logger Lite software help students interpret the results of their experiments and can be used to create professional laboratory reports.

Go!Temp Cost: $39

Leave the lecture hall behind and join us for NSTA’s first un-conference experience, taking place in Minneapolis this October 27-29, and Portland, November 10-12!

What should you expect at this un-conference?

Taking place during the first two NSTA fall conferences on science education, this will give you the opportunity to continue the conversation, not the lecture. Many of our attendees have asked us to find a way to bring together people for engaging “offline” conversations. When something special bubbles up at the conference, or if there is a groundswell of people asking about a certain topic, we’ll make time for conversation and real-time reflection. Participants will be afforded an opportunity to present their findings from the conference while connecting with other science education enthusiasts.

Who will be invited to attend?

Anyone who attends the conference is invited, and we’ll use social media to connect with teachers who long to be part of NSTA conferences but are unable to travel. We’ll bring together conference attendees, favorite presenters, teams involved in the Maker Movement, community partners, science teacher superheros, your favorite authors, and perhaps a few STEM stars.

What is the expectation during your “Un-Conference Experience”?

The atmosphere will be relaxed, open, friendly, and fun. This will ensure that all participants, especially those joining for the first time, will feel welcome and respected. Learning will be spontaneous and inviting, providing you with information and, who knows, maybe a new comrade in education.  

Where and when will it be?

The first two will be in the exhibit hall, onsite at NSTA’s Minneapolis Conference, October 27-29, and the Portland Conference, November 10-12. We’ll bring updates to you live, via NSTA’s Twitter feed and Facebook page.

How can I suggest topics?

Add your ideas to the comments here, or tweet your ideas with the #NSTA16 hashtag. We’ll be monitoring the hashtag and encourage you to join us in this new venture.

Who is the host?

This is being supported by the NSTA staff and leadership, and I am the host. Please feel free to reach out to me via Twitter as well, and follow me at @DedricMcghee.

Two new children’s books published by NSTA Kids, a division of NSTA Press, are filled with rich illustrations and highlight the importance of discovery, observation, and investigation.

In From Flower to Fruit, young scientists are encouraged to use a magnifying glass to study plants in a garden. The book, intended for grades K–4, takes readers on a colorful journey that teaches them about flowers, fruits, and bees, and how plants have special parts that help them reproduce.   

The authors, Richard Konicek-Moran and Kathleen Konicek-Moran, write that flowers can provide “great teaching and learning opportunities for all ages,” and that botany is underrated as a topic for investigation because it is often considered a categorizing science. “We hope this book will introduce the discovery and wonder of botany,” the authors write.

In addition to the story, the authors include six activities for children and informative background information for parents and teachers. The book comes alive with beautiful and helpful drawings, illustrated by coauthor Kathleen Konicek-Moran. These detailed illustrations reinforce the role observation plays in science. “When you draw something, you look very closely at it and see things you might have missed if you were not drawing it,” Mrs. Maria—one of the story’s characters—says in the book.

Sketching, writing, and recording data and observations is also a major theme of the other new NSTA Kids book—Notable Notebooks: Scientists and Their Writings. The author, Jessica Fries-Gaither, captures why journaling is such an important part of the scientific process.

The book, written in rhyme for grades 3–5, profiles a diverse group of nine scientists (both modern day and past) and provides examples of their writings and illustrations. Dr. Jane Goodall is shown studying drawings of chimps in her notebook, Galileo’s diagram of planetary orbits is featured, and a section on Charles Henry Turner displays how his notes uncovered patterns in insect behavior. “A notebook is a place to plan experiments or tests and also to see patterns in what data could suggest,” the author writes.

Notable Notebooks includes four steps to help students create their own science notebooks. The steps encourage students to write down their findings and wonderings and share their work with family, friends, or teachers at school. “What makes a notebook special? It’s a place to think and dream, to write down thoughts and questions about all that you have seen,” Fries-Gaither writes.
