Erickson, Brian; Crews, Tracy – Science Teacher, 2019
This article describes a five-lesson curriculum that introduces students to the primary cause, multiple predicted impacts, and possible solutions to ocean acidification. It builds upon the strengths of over 90 existing teaching resources on the topic while also contributing new ways to teach about the impacts and solutions to this pressing…

Butera, Brett; Esser, Scott – Science Teacher, 2019
Citizen science can provide insightful data to inform decisions, while also serving to enhance ecological awareness and foster environmental stewardship among participants. In this article, high school student citizen scientists investigate how trees respond to changing mountain climate during a field trip to Rocky Mountain National Park (RMNP) to…

Trautman, Nancy; Manker, Jeff; Mitchell, Kiandra; Kahler, Phil – Science Teacher, 2019
In the 1990s, classes throughout the United States began participating in Classroom FeederWatch, sending data on birds they had seen at feeders in their schoolyards to the Cornell Lab of Ornithology. The launch of eBird in 2002 opened up new possibilities for submitting data on all types of bird species, allowing users to record and upload…

Luft, Julie A.; Whitworth, Brooke A. – Science Teacher, 2019
Science teachers need to consider how they want to grow professionally. Thinking about one's future involves identifying the knowledge, practices, and attributes needed in a new role. By using a framework such as the science education trajectory (SET), teachers can more easily consider their professional options and work strategically toward them.…

Chowning, Jeanne Ting; Wu, Regina; Brinkema, Caren; Crocker, Wendy; Bass, Krystal; LaZerte, Debbie – Science Teacher, 2019
DNA extraction from strawberries is a well-known procedure that allows students to visualize DNA and to recognize that living things contain DNA (NHGRI 2018, Science Buddies 2013). In this article, the authors describe a modification to the traditional DNA extraction protocol that promotes student agency in experimental design and also emphasizes…

Perry, Anthony; Estabrooks, Leigh – Science Teacher, 2019
The "Next Generation Science Standards" ("NGSS") emphasize integrating engineering design into the science classroom (NGSS Lead States 2013). Inventing is an authentic and relevant classroom approach, regardless of content area, located at one end of a design continuum opposite from routine problem solving. Invention, at the…

Cian, Heidi; Marshall, Jeff; Cook, Michelle – Science Teacher, 2019
The "Framework" (NRC 2012) and "Next Generation Science Standards" (NGSS Lead States 2013) require science teachers to think differently. Specifically, NGSS's performance expectations now require that three domains (disciplinary core ideas (DCI), crosscutting concepts (CCC), and scientific and engineering practices (SEP)) be…

Countryman, Lyn – Science Teacher, 2019
There is clear scientific evidence linking climate change to human activity. Despite this, we still find numerous public figures claiming there is no climate change, or that climate change data is "fake news." Societal polarization around climate change (Worland 2017; Pernett 2017; McCright and Dunlap 2011) can provide students with…

Price, Argenta; Wieman, Carl; Perkins, Katherine – Science Teacher, 2019
Interactive science simulations (sims) have become popular tools for science educators, and research confirms that sims can improve student learning (Rutten, van Joolingen, and van der Veen 2012). Over the past 15 years, the PhET Interactive Simulations project at the University of Colorado Boulder has created a collection of 150 open (free)…

Briscoe, Michael – Science Teacher, 2019
FLEET is a free ship-design simulator that reaches students in their native environment--video games. It is also a physics simulator that applies content first learned through hands-on scientific investigations. Using FLEET, students design and use ships for various naval missions by mastering scientific concepts such as force, energy, and work,…

Maeng, Jennifer; Gonczi, Amanda – Science Teacher, 2019
The idea that plants do photosynthesis but do not do cellular respiration is a common misconception among middle and high school students that often stems from an over-simplification of these processes in diagrams and formal science instruction. The activity presented here uses a conceptual change approach (Nussbaum & Novick, 1982) and an…

Cubbage, Tom – Science Teacher, 2019
For most people, coffee roasting is a mysterious process. Chemically, it's equally mysterious; the roasting process gives rise to over 800 compounds. The science of coffee, from seed to bean to cup of aromatic brew, includes multiple areas of science content for students, and actively engages them in many science and engineering practices. Ask…

Pearlman, Melanie – Science Teacher, 2019
Spices, of course, do not make a meal, but they make a meal more enjoyable and memorable. Games do the same, allowing teachers to interact with their students in a different way than they normally do. They also have the potential to challenge and assess students' understanding of content. Games allow teachers to "play" with their…

Hewitt, Paul G. – Science Teacher, 2019
Some introductory physics courses begin where student interest is thought to be highest--in waves, sound, and light--before speed, velocity, and acceleration. For students with math difficulties, this order makes sense. But most physics courses, including the author's own, begin with a study of motion. Why? Mostly due to tradition, he admits. When…

Hewitt, Paul G. – Science Teacher, 2019
Part 1 of the series looked at teaching speed and velocity. Part 2 considers the teaching of acceleration in physics. Teachers may find it okay to hurry through the concepts of speed and velocity because they are intuitive. But teachers cannot hurry through acceleration quite so quickly because it is not intuitive. Whereas velocity is a rate of…
