STEM Sims: Data Visualization
Introduction
STEM Sims provides over 100 simulations of laboratory experiments and engineering design products for integration into STEM classroom instruction. One particular simulation found on this site, Data Visualization, stimulates the imagination of students by having them analyze a graphic representation of Napoleon’s 19th Century invasion of Russia. Using data provided in a 1869 graphic representation by Charles Minard, students are able to make decisions and investigate Napoleon’s military campaign. Moreover, Data Visualization is aligned with national (NGSS) standards (see below) and is compatible with state standards as well.
The simulation provides students with a brochure (see link below), a pre-assessment quiz, and introductory background information about the concepts of data visualization. The simulation offers students the opportunity to use data analyzation skills integrates mathematics/science and social studies content. Therefore, this activity allows science teachers to simulate Napoleon’s conquest via a problem-solving approach that evaluates ” how and why” his campaign failed. As has been the case with other STEM Sims activities, we found that higher levels of Bloom’s Taxonomy are applicable (i.e., Analysis and Evaluation), which makes this activity worthwhile for teachers who like to emphasize critical thinking in their classrooms.

“To be a good science teacher, it’s important to keep on top of the latest news and innovations in science,” says Dean Goodwin, grades 9–12 biology and environmental science teacher at The Tatnall School in Wilmington, Delaware. “If any of this can be related to topics we have just covered, or are about to cover, or is just an amazing piece of science news, I share [it] with my classes…My aim is to ensure that students understand that science is not at all static, but we are continually learning and expanding our knowledge in science…It also helps to separate some of the misinformation about science that seems to abound in some areas of the media…The students question, and critically think, about what is presented.”
Goodwin says he aims to “[get] students energized to differentiate between science fact and science fiction” by comparing “what pops up on Facebook” to legitimate science news sources like the National Science Foundation. Sometimes he has students design and conduct their own experiments based on ones they’ve read about in the news—such as the 2013 experiment by ninth graders in Denmark to test the effect of cellphone radiation on a plant—and compare their data with the data they read about. “I want to get students to think and behave like scientists,” he explains. “I want them to have the courage to [test a seemingly] crazy idea. This is what scientists do.”
Goodwin has designed—and will teach next year—two trimester elective courses that incorporate current events. In Science Today, students will research science news from journals, websites, television, radio, and social media and analyze the authenticity of the news sources. They’ll discuss the science behind the news and learn how to differentiate between real science and junk science.
Students taking The Science of Climate Change will use websites to keep abreast of the latest effects of climate change on the planet and produce materials that will be disseminated through the school’s 350DE at Tatnall climate education group, which is also the Delaware chapter of 350.org, an international environmental organization that publicizes the increasing levels of carbon dioxide to encourage world leaders to address climate change. Tatnall students worked with Goodwin to found 350DE at Tatnall. “This is a very passionate group of students who want to correct bad information about science,” he observes.
When she taught high school science, Kathryn Kennedy says she “constantly saw the need to include current events in my lessons, to give students the big picture in science.” This was especially important in her Bioethics unit, which touched on issues like “should stem cell research be conducted, whether individuals should be able to refuse medical assistance due to religious conflict, [and] whether or not paralympians should be able to compete in the Olympics.” Students “practiced creating logical responses using evidence…to support their argument on an issue,” she adds. The unit helped them “determine what they valued,” that “others have different opinions, and why,” and that “they can have an opinion based on their values, but they need to look at scientific evidence to justify [it].”
Kennedy, now senior laboratory supervisor for the General Chemistry labs at the College of the Holy Cross in Worcester, Massachusetts, is creating The Periodical Table (TPT; refer to https://goo.gl/6stfPa), a website for middle and high school teachers with lessons that incorporate current events, reading resources, and eventually, science-themed books. TPT’s lessons include Climate Change as a National Security Issue, in which students read the transcript of a National Public Radio interview of Retired Brigadier General Gerald Galloway about how climate change will affect the military in protecting Americans at home and abroad. Students then analyze the enacted 2016 budget and requested 2017 budget for the Department of the Defense. “It is powerful to tell students to keep up with current events so they can vote responsibly and be informed citizens,” she maintains.
To prepare her students to discuss controversial news topics, Kathleen Chesmel, ninth-grade physics teacher at New Egypt High School in New Egypt, New Jersey, has them conduct peer reviews of their projects. “We work on drafting comments that help improve the work being reviewed and avoid focusing on personal attacks or statements [unsubstantiated by] evidence…Once they have become comfortable with peer review (both giving and receiving), it is easier to allow open discussions of [these topics],” she explains.
Sensitive topics arise “as part of my science news class opener,” says Diana Allen, seventh-grade life/environmental science teacher at Sanford Junior High School in Sanford, Maine. From “a list of well-known science news websites” she has vetted, she invites students “to find a sci/tech–based article that is of interest to them…Then they [briefly summarize it] and what about it [that] interested them.” During discussions, she highlights “careers being touched upon in the article” to get students to begin exploring career options, she notes.
Science news engages students “in some of the Next Generation Science Standards (NGSS) practices,” says Allen. “I’m doing more media literacy” since the NGSS were developed, she adds. The “three-dimensional learning [of the NGSS] brings about more independent student thinking.”
“Current events are incorporated in specific units” in grades K–6 science, says Ana Appel, associate director of Lower School Science at Ascend Public Charter Schools in Brooklyn, New York. In a fifth-grade unit, for example, “we will be framing one performance expectation (PE) around current events in global warming and climate change.” Students will do “a case study on Rachel Carson and the creation of the EPA [Environmental Protection Agency] and compar[e] it to the recent hearings of [EPA Administrator Scott] Pruitt before the Senate subcommittee. Students have already learned about global warming and will be able to relate this to the idea of Earth’s resources and the environment.”
Next, students will “read about communities that are currently intervening to protect the resources and environment from recent news sources…and learn to differentiate about community impact on a local, regional, national, and international level (the clarification statement for the PE),” Appel explains.
“I find it is important to connect science to policy” using current events, Appel contends. “I recently held a professional development with my teachers on how to teach policy and science while remaining unbiased. I used a video clip and had teachers analyze how the politicians discussed science using opinion versus fact and how this plays out in the classroom. We then discussed how to best teach our scholars to develop their own opinions about difficult concepts that impact laws, especially when we have our own opinions.”

Figure 1. A. Notre Dame Cathedral, Paris. B. St. Paul’s Cathedral, London.
When teaching how tension and compression relate to geometrical structures such as bridges, arches, and domes, I show a picture of the Notre Dame Cathedral in Paris (Figure 1A), completed in the 14th century. I point out the elaborate buttresses that keep the walls from pushing outward while supporting its weight. Architects of the day had not yet learned how to hold up a very large, massive building without external propping. This was accomplished in the 17th century in the construction of St. Paul’s Cathedral in London (Figure 1B).
Why, I ask, is St. Paul’s Cathedral free of such buttresses? Aha, inside its famous dome is an inner “secret dome” that provides structural support. To understand this, let’s first investigate the roles of tension and compression in structures.
Tension
I stretch a length of rope taut, explaining that the stretching force we call tension acts in a direction parallel to the direction of the rope. When I let the rope sag between my hands, tension vectors within the sagging rope continue to align with the rope. The curved shape of the sag is determined by this alignment of tension vectors. Likewise for a sagging chain or sagging cable.
A rope, chain, or cable supported at its ends and hanging only by its own weight takes the shape of a special curve called a catenary. I sketch a sagging
Figure 2. Tension between links in the chain align with (are parallel to) the curve of the chain. The curve is a catenary.
chain on the board and show that tension vectors between links of the chain are everywhere parallel to the curve with no components of tension perpendicular to the curve (Figure 2). The chain ends can be held at different distances apart, making the curve deep or shallow. As long as the chain supports only its own weight, it’s a catenary.
If a sagging chain or cable supports weight that is distributed uniformly in a horizontal direction, as is approximately true in a suspension bridge, then the shape of the curve is a parabola, the same curve followed by a tossed ball. The curved cables of a suspension bridge or suspended roadway are approximately parabolas. Only if the cable supports only its own weight—such as sagging clotheslines, power lines, and strands of spider webs—is the shape a catenary.
Compression—and the inverted catenary (an arch)
Of particular interest is an inverted catenary, where internal forces are of compression rather than tension. When a free-standing arch takes the shape
Figure 3. Curves of the sagging chain held by Manuel and of the Gateway Arch in St. Louis are catenaries.
of an inverted catenary, the weight of the arch is supported by compression forces pressing along the arch’s curve. There are then no compressive forces perpendicular to the curve. My grandson Manuel delightfully shows two catenaries in Figure 3, one of a suspended chain and in the background the Gateway Arch in St. Louis, Missouri.
I sketch the Gateway Arch, showing that compression vectors between adjacent slabs that make up the arch are everywhere parallel to the curve (Figure 4). I tell students that they could make a stable mini-arch out of slippery
Figure 4. Compression vectors between slabs are everywhere parallel to the Gateway Arch.
blocks of ice if the shape of the arch is a catenary! But if the shape were any other, such as a semicircle, blocks of ice would squeeze free, and the arch would collapse. Where strength is important, modern arches are usually catenaries.
The three-dimensional catenary: a dome
I ask students to imagine rotating an arch through a complete circle. I then help them to reason that the result would be a dome. Just as for an arch, the weight of any dome produces compression, which tends to collapse the dome unless the compression forces are aligned with (parallel to) the dome’s curve—in other words, a catenary.
Christopher Wren, the brilliant architect who designed St. Paul’s Cathedral, believed that a hemispheric dome (half of a sphere) would be the most
Figure 5. The nesting domes of St. Paul’s Cathedral.
beautiful but knew it would be too weak by itself to hold the extremely heavy lantern structure he planned to place atop it. So, he cleverly designed three nesting domes: a hemispheric outer dome, a steeper inner dome, and—hidden in the middle—a dome that approximated a catenary and provided the necessary structural support (Figure 5).
Modern domes that span vast areas without the interruption of supporting columns are most often three-dimensional catenaries. There are shallow domes (the Jefferson Memorial) and tall ones (the United States Capitol). The catenary principle is employed in the Houston Astrodome, the roof of Washington Dulles International Airport, and the igloos in the Arctic.
The catenary egg
To relate this physics concept to the natural world, I introduce students to the shape of a common egg. People have always wondered why crushing an egg by
Figure 6. Why does squeezing an egg along its long axis fail to break the egg?
squeezing along its long axis is so difficult (Figure 6), while a chickie can easily poke its way out from the inside. Penetrating the shell from inside deals with tension rather than compression. Only the weaker shell tension must be overcome. But what makes the compressive forces on the outside so strong? Can you guess? I ask. (And of course they can.)
A double catenary
I direct student attention to the two most curved surfaces of an egg: its two ends. With an egg held so that first one end, then the other, is on top, they see that a chain follows the contour of the egg—at each end (Figure 7). Aha! Students are delighted to see that both ends of the egg, one more strongly curved than the other, are catenaries. Nature has not overlooked the catenary!
Figure 7. A chain follows the curves of an egg—catenaries at both ends.

Come join us at the 6th Annual STEM Forum & Expo. It is the event where early childhood and lower elementary teachers need to be. It is a unique event where you will find a great deal of focused ideas on how to engage, nurture, and teach what our little ones are already so curious about. Science, technology, engineering, and math is all around our students and they have a natural love for figuring out how things work and why. The STEM Forum is a wonderful opportunity for educators in the early years to find resources that will help build your knowledge on integrating STEM into your lessons as well as give you some great fun ideas you can take immediately back to the classroom and use the next day.
As early childhood and lower elementary teachers we tend to focus on making sure our students are first learning and practicing their foundational skills like, the alphabet, numbers, reading, and writing and perhaps forget the importance of STEM to our students’ futures. We need to teach them how to be those innovative thinkers, problem solvers, and creators of the future and it all starts with us! With a strong understanding of STEM and how to go about presenting it to young learners that is exactly what you as a teacher can do for your students. Attending the conference will give you many opportunities to find ideas that you can use in planning your literacy blocks, but also effectively integrating science or engineering into some of those already great lessons. There are so many books that lend themselves to science and engineering. Some of the sessions at this year’s STEM Forum will focus on how to use science and engineering with literature as well as give you some activities to try with your own students. Presenters are educators, like myself, that have come to share what has effectively worked for them. They bring along great resources and knowledge that they have used or found helpful in developing their lessons that they are more than happy to share with other educators.
Our young students deserve to explore and allow their natural curiosity to guide their learning. As early childhood and lower elementary teachers our job is to focus that natural curiosity and assist them in making important connections about the world and their place in it. So please, come and join us at the 6th Annual STEM Forum & Expo. You will not believe how many excellent and focused sessions for young learners you will find that will assist you in becoming a well-rounded STEM educator. We hope to see you there!
Adriana Guerra began her teaching career at E.P. Foster STEM Academy 12 years ago.

Legislative Update

First up—guidance you do not want to miss: Last week, the U.S. Department of Education issued a seven page memo detailing possible uses of federal funding through ESSA to support STEM education. The must-see document has helpful examples of how states, schools and districts can leverage ESEA, IDEA, and Perkins Funds for STEM education. The letter can be found here.
Congress and the FY2017 Budget
The budget grabbed all the attention last week, as the Continuing Resolution (CR) for FY2017 programs official ran out on April 28 amid the ensuring drama over whether to shut down the federal government, actually fund FY2017 programs (we are now halfway through FY2017), extend the CR for another week, fund the wall, and finish a health care bill (Congress choose to extend the existing CR for another week).
Late Sunday night (April 30) POLITICO reported that a funding agreement was in place through the end of September. It appears that funding for Student Support and Academic Enrichment (SSAE) Title IV block grant program for fiscal year 2017, authorized by the Every Student Succeeds Act, will be at $400 million this year, a fraction of the ESSA authorization level of $1.65 billion. With the low funding level, Congress changed the distribution for this program: money will go directly to the states and will be a competitive grant program lead by the states (this year only), instead of a formula program to all schools. More on the Title IV program here.
The Trump <skinny> budget for FY2018 proposes $59 billion for the Department of Education, a $9.2 billion cut to the Education Department’s $68 billion budget, which would cut agency spending by 13 percent below the 2017 CR level. Read more here.
Update on Every Student Succeeds Act
Several states have submitted their plans to implement the Every Student Succeeds Act, and more are working to meet the September deadline for ESSA plans. Right now 10 states have plans out in some form. The U.S. Department of Education (ED) has 120 days to review the plans; if it makes no comment during that period, the plans are considered approved.
What’s not in the state plans? Expanded school choice programs, reports U.S. News & World Report. Many states are proposing to track student scores with new methods beyond just test scores, reports PBS.
In an interview last week Education Secretary Betsy DeVos told Fox News that the Every Student Succeeds Act does away with the whole argument about Common Core and “it leaves up to the states” to make decisions about which standards to choose. “There really isn’t any Common Core anymore,” stated DeVos. President Trump and his advisors have repeatedly said the Administration would repeal Common Core.
Spotlight on School Vouchers
There has been a lot of press attention on school vouchers lately. Many advocates believe that the national school voucher program President Trump has called for could be fashioned after the tax credit scholarship program in Florida—created by former Governor Jeb Bush—that now pays private school tuition for almost 100,000 low income students so that they can attend private, mostly religious schools.
A national tax credit based on the Florida model to expand school vouchers nationwide could be inserted into a tax reform package and could be passed through a simple majority in the Senate. Sen. Marco Rubio (R-Fla.), and Rep. Todd Rokita (R-Ind.) have proposed legislation that would create a program similar to the Florida tax credit scholarship at the federal level. Read more here.
In addition to Florida, currently about 17 states also offer some type of tax credit scholarships. These programs provide tax credits to individuals or corporations that donate to a state-approved organization, which then awards funds to working class families for private school tuition.
In anticipation of school voucher legislation, a group of Senate Democrats has requested that the Government Accountability Office (GAO) conduct a study to investigate the structure and accountability of tax credit scholarship programs in the states and determine whether state voucher programs have resulted in mismanagement of public funds.
Education Dept. Needs to Improve Oversight of 21st Century Program
A GAO report last week found that the Department of Education oversight of afterschool programs funded via the 21st Century Program was lacking.
From the report: “Relevant research we reviewed that compared program participants to those of non-participants suggests that the 21st Century program is effective in improving students’ behavioral outcomes, such as school-day attendance and reduced disciplinary incidents, more often than their academic outcomes. However, because Education’s current 21st Century performance measures primarily focus on students’ reading and math scores on state tests, Education lacks useful data about whether the program is achieving its objectives to improve students’ behavioral outcomes such as attendance and discipline—the areas where the program most frequently has a positive effect. Education officials have not substantially revised the program’s performance measures since 1998, in part because its authorization lapsed from fiscal years 2008 through 2016. Leading practices in performance measurement call for federal agencies to align performance measures with program objectives.”
President Trump proposed zeroing out this program in the FY2018 budget, after OMB Director Mick Mulvaney told reporters of “no demonstrable evidence” that after-school programs help students. The GAO is considered the watchdog of government.
Executive Order to Rid Schools of “Federal Overreach”
And, finally, President Trump last Wednesday signed an executive order that directs Education Secretary Betsy DeVos to determine where the “federal government has unlawfully overstepped state and local control.”
Administration officials told USA Today that “In recent years too many in Washington have advanced top-down mandates that take away autonomy and limit the options available to educators, administrators, and parents,” and the executive order puts an end to this overreach, yet admitted to reporter Greg Toppo that DeVos already was empowered to do this.

Congress and the FY2017 Budget

Recently, there was a question about what to do when students were off-task. I conduct many professional development programs, and I could use some ideas to keep adult participants on-task! —T., Virginia
As a presenter, it’s frustrating to see participants grading papers, texting, or reading the news. But in all fairness to our colleagues, their inattention may stem from experiences with compulsory professional development (PD) sessions that were “sit ‘n’ git,” conducted by drop-in presenters who were not familiar with the school’s culture, had no teacher input into the content, or held afterschool when everyone was tired.
I shared your question with a colleague with whom I have held many PD sessions. We agreed that in addition to well-planned content, it is important to engage the participants with effective strategies they can apply in their classrooms:
Relax and realize, as an administrator told me, some people aren’t happy unless there’s something to complain about. One of our workshops was rated low by a participant because “I don’t like tomato on my sandwich” that was in a provided lunch.

This week in education news, Bill Nye thinks Pruitt and DeVos are the least qualified people for their agencies; science advocates double down on their outreach attempts; some teachers may be misleading students about climate change; Trump signs executive order reviewing federal role in education; Alabama is changing how it teaches science; and researchers debate how educators and policymakers can better understand what influences teacher shortages from state to state.
What The Latest Assaults On Science Education Look Like
Each year, anti-science education legislation is introduced in state legislatures around the country — and, in a few cases, has been passed. So what is an anti-science education bill — and how many have been introduced in 2017? Click here to read the article featured in the Washington Post.
Bill Nye: Pruitt, DeVos ‘The Least Qualified People On The Planet’ For Their Agencies
Bill Nye the “Science Guy” is taking aim at President Trump’s Cabinet picks, singling out Environmental Protection Agency Administrator (EPA) Scott Pruitt and Education Secretary Betsy DeVos as “the least qualified people on the planet” to head their agencies. Click here to read the article featured in The Hill.
After The March: Science Advocates Prepare For A ‘Marathon’
The March for Science brought tens of thousands of science supporters into the streets of Washington, D.C., and to around 500 satellite marches around the world on Saturday (April 22). Now, supporters say, the challenge is to turn the energy in the streets into sustained science advocacy. After the march, science organizations and universities are doubling down on their outreach attempts. Click here to read the article featured on Live Science.
Senate Bill 393 in Oklahoma permits teachers to paint established science on both evolution and climate change as “controversial.” The “controversy,” however, doesn’t really exist — more than 97 percent of actively publishing, accredited climate scientists agree that global warming trends over the past century are directly attributable to human activity. And some teachers might already be misleading students. Click here to read the article featured in VICE News.
Betsy DeVos Said, ‘There Isn’t Really Any Common Core Any More.’ Um, Yes, There Is.
Recently, DeVos told Michigan radio station host Frank Beckmann that the Every Student Succeeds Act effectively does away “with the notion of the Common Core,” Education Week reported. The ESSA, the successor law to No Child Left Behind, left it to states to decide on their standards, but, then again, the states had that right before. And many states are still using them. Then on Monday, DeVos told Fox News anchor Bill Hemmer that the ESSA “essentially does away with the whole argument about Common Core.” Click here to read the article featured in the Washington Post.
In Elementary School Science, What’s At Stake When We Call An ‘Argument’ An ‘Opinion’?
As more teachers are using both the Common Core State Standards and the Next Generation Science Standards, they will increasingly be confronted with a challenge: The standards in literacy and science—and the research literature in the two fields—disagree about when and how students learn to form arguments. Click here to read the article featured in Education Week.
Trump Signs Executive Order Reviewing Federal Role In Education
President Donald Trump signed an executive order on Wednesday aimed at decreasing the role of the federal government in education while giving states and local school districts more power over decision-making. Trump called the called order, which directs Education Secretary Betsy DeVos to study federal overreach in education, “another critical step to restoring local control, which is so important.” Click here to read the article featured on NBCNews.com.
Alabama’s In The Mainstream With A New Way To Teach Science
Science teaching is changing across America, and Alabama is changing how it teaches science, too. But will the changes be enough or too much? Dr. Bruce Alberts, a biochemist who headed the National Academy of Sciences and edited “Science” magazine, recently discussed the new way at Huntsville’s HudsonAlpha Institute for Biotechnology. Afterward, Dr. Neil Lamb, the institute’s vice president for educational outreach, talked about Alabama’s approach. Click here to read the article featured on Al.com.
AERA: What Do We Mean When We Talk About Teacher Shortages?
Debates over perceived teacher shortages often conflate different problems and make it more difficult to find sustainable ways to get every student a good teacher. That was the consensus at one of the opening symposiums of the American Educational Research Association’s annual conference on Thursday. Linda Darling-Hammond, founder of the Learning Policy Institute, at Stanford University think tank, led researchers debating how educators and policymakers can better understand what influences teacher shortages from state to state.

It has been said that science began “whenever and wherever [people] tried to solve the innumerable problems of life” (Sarton 1952). The Next Generation Science Standards (NGSS Lead States 2013) call for the pursuit of scientific literacy for all through science instruction. This includes acknowledging the contributions to science of those whose communities have been historically marginalized.
The contributions of non-Europeans
Unfortunately, science educators often fail to acknowledge the contributions of non-Europeans. We also fail to convey the complex, messy, culturally contextualized aspects of scientific progress not found in most textbooks.
Consider, for example, the story of the smallpox vaccination. English scientist Edward Jenner has been credited with developing a cure for the deadly disease, a cure that ultimately lead to the acceptance of immunology in the 1800s (Johnson and Raven 2006). However, records indicate that long before Jenner was born, Africans practiced a form of inoculation by scratching the arm of a healthy individual with a tool infected with the offending virus, eventually protecting the person from the illness.
During a smallpox outbreak in the American colonies in the early 1700s, a slave named Onesimus explained the African practice to a puritan minister, Cotton Mather, who in turn persuaded a local doctor, Zabdiel Boylston, to use it (Herbert 1975). Their willingness to accept African knowledge saved lives during the outbreak. Unfortunately, few textbooks addressing the origins of vaccinations mention the African practice or the story of Onesimus.
Although there is little empirical evidence to support the seemingly intuitive practice of incorporating the history of science to improve students’ understanding of the nature of science (Abd-El-Khalick and Lederman 2000), many science educators acknowledge the potential of such instruction to augment student understanding of science.
Finding fresh resources
If teachers are to engage their diverse students in more meaningful discussions about the history and nature of science, we have to go beyond the sterile stories propagated by textbooks and research other resources to support our efforts. Good choices include the books Acid Tongues and Tranquil Dreamers (White 2001), A Short History of Nearly Everything (Bryson 2003), Blacks and Science, Volume Three (Walker 2013), and Hidden Figures (Shetterly 2016), the book on which the Academy Award–nominated film was based.
Students need to see connections between science learning and their experiences and cultures (Gay 2002; Ladson-Billings 1992). Becoming more inclusive in our representations of science in the classroom is important to developing an understanding of who does science, how science is done, and how science progresses. This will benefit students, teachers, and society.

It has been said that science began “whenever and wherever [people] tried to solve the innumerable problems of life” (Sarton 1952). The Next Generation Science Standards (NGSS Lead States 2013) call for the pursuit of scientific literacy for all through science instruction. This includes acknowledging the contributions to science of those whose communities have been historically marginalized.

Science Scope – Math and Science
“Why are we doing math in science class?” my students would ask. But they soon realized that math could be applied to other subject areas such as science, especially in terms of measurement, graphing, and data analysis. As the Editor notes, two of the NGSS science and engineering practices are related to math. The featured articles this month encourage this relationship.
Articles in this issue that describe lessons include a helpful sidebar (“At a Glance”) documenting the big idea, essential pre-knowledge, time, and cost. The lessons also include connections with the NGSS.

The Science Teacher – Science for All
TST’s Editor this month quotes NSTA’s position on multicultural science education and notes “In our diverse classrooms, we must champion ideals of inclusion and allow all people to feel valued and safe.” This month’s issue has featured articles with ideas to deal with the differences in ethnicity, socioeconomic status, gender, physical disabilities, learning differences, and various levels of English proficiency in our classrooms.
The lessons described in the articles include connections with the NGSS.

Knowing that content material is most engaging when students can relate to it, I always begin my year with a student survey. The questions are designed to help me design lessons to be as student-focused as possible. Knowing my students’ interests and history also helps me identify phenomena and storylines that will be the most engaging for them. The phenomenon is the hook to capture students’ interest and inspire their curiosity; storylines provide links between performance expectations. The combinations of phenomena and Performance Expectations are virtually endless.
I write my units using my own template which is a hybrid of Understanding by Design and Universal Design for Learning. Click here to view and download my template
Pre-planning: I recommend you bundle Performance Expectations into a logical storyline and include driving questions to guide students toward conceptual leaps. For example, when learning the fact that all cells come from existing cells, I expect a student to ask about the origin of the first cell. I use these questions to devise investigations that will help students find answers and develop their own questions. Asking probing questions during these activities is critical. I recommend you plan ahead and make your questioning targeted and intentional so that it causes students to think deeply and make sense for themselves.
Two tools I have found that are helpful include a Talk Activities Flowchart developed by STEM Teaching Tools and Goals for Productive Discussions and Nine Talk Moves published by TERC.
Let me share the stages I go through when I begin planning my science instruction.
Stage 1: Determine “All, Most, Few.” In this first stage, I differentiate the concepts and skills that all students need to achieve, the higher concepts and skills most will reach, and the extension activities I can provide to students who have advanced skills and interests. I then write two-to-four essential questions that make intentional reference to Crosscutting Concepts, scaffold my unit from lower- to higher-order thinking using Disciplinary Core Ideas, and determine which Science and Engineering Practices will be addressed and what skills I will target.
Stage 2: Looking for Evidence. Daily formative assessments inform instruction and guide my lesson planning. Formative assessments range from observations and discussions to tracked response assignments like Plickers, Quizzizz, Kahoot, EdPuzzle and Quizlet. Summative assessments are more time-intensive and require students to demonstrate their learning independently. These assessments differ between students and include poster presentations, informational website development, TED-style talks, and student-created lessons to teach younger students. To ensure I am encouraging 21st century and literacy skills, I also include a variety of digital and research components, time for modeling and reflection, and include elements of publishing or presentation for both formative and summative assessments.
Stage 3: The Blueprint. This final stage involves drafting a rough learning plan that includes critical input and inquiry lessons. I provide notes and other introductory presentations that help guide students and provide essential knowledge for the unit. Most of the lessons are student-centered and inquiry-based.
Taking it into the classroom:
Because I teach in a science lab with immovable lab benches, I’ve added a variety of seating options to facilitate collaboration and peer review among students and allow me to split the class into stations. The set-up includes two large round tables with chairs and a set of modular sofa sections.
I love to teach in stations! Students can be break into groups which facilitates differentiation and makes it possible for me to support the “all, most, few” idea presented in Stage 1.
My favorite resource when I first started planning 3-dimensional units includes the NSTA Press® book, Translating the NGSS for Classroom Instruction by Rodger Bybee. Click here to view a sample chapter.
My favorite resource for three-dimensional planning support comes from the American Museum of Natural History. Click here to view and download it.
