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…

Reynolds, Julie – Science Teacher, 2019
A lesson that focuses on the intricate co-evolution of flowers with their pollinators is one way to help students learn the delicate balance in nature and help ensure that our actions do not upset this balance. In this lesson students use the engineering design process to engineer a flower that is a perfect model for its chosen pollinator. Next,…

Carrigan, James; Bodzin, Alec; Hammond, Thomas; Rutzmoser, Scott; Popejoy, Kate; Farina, William – Science Teacher, 2019
Mobile geospatial technologies enable high school students to engage in authentic scientific data collection and analysis that promote spatial-thinking and reasoning skills, as well as problem-solving in a school's local environment. We developed and implemented an Ecological Services investigation aligned to the Next Generation Science Standards…

Lausch, Rabecca; Ross, Danielle K. – Science Teacher, 2019
Understanding natural selection and adaptation are important precursors to learning evolution (NGSS Lead States 2013), the central unifying principle of biology. This lesson sequence, guided by the Five Practices Model (Cartier et al. 2013), incorporates data described by Andersson (1982) that details female choice in a population that eventually…

Wagler, Ron; Wagler, Amy – Science Teacher, 2019
The primary learning objectives of this "Next Generation Science Standards" (NGSS; NGSS Lead States 2013) aligned activity is to help high school biology students experience firsthand the role of replication in scientific inquiry and food preference as a behavioral reproductive trait of the Madagascar hissing cockroach. The secondary…

Bernard, Rachel; Henegan, Colleen – Science Teacher, 2018
For many students, the first--and sometimes only--chance to look through a microscope is in high school biology class, where they observe plant and animal cells up close. Even in college, few students use a microscope for a subject other than biology. Thus, it can be a surprise to learn that microscopes are a primary tool used to understand the…

Stoeckel, Marta R. – Science Teacher, 2018
Along-standing energy lab involves dropping bouncy balls and measuring their rebound heights on successive bounces. The lab demonstrates a situation in which the mechanical energy of a system is not conserved. Although students enjoyed the lab, the author wanted to deepen their thinking about energy, including the connections to motion, with a new…

McPherson, Heather – Science Teacher, 2018
Students often confuse the functional differences between motion "transmission" and "transformation" systems. Students find it difficult to conceptualize differences between the specific systems. In this article, the author describes a technology and engineering unit that incorporates problem-based learning (PBL) to assist…

Bautista, Nazan; Diekman, Amanda; Fuesting, Melissa – Science Teacher, 2018
Explicit and reflective teaching of communal goals forms connections between STEM content and practices, providing in- and out-of-class opportunities to reflect on how communal goals relate to class activities. This lesson integrates the concepts of "prosociality" (science helps others and gives back to the community) and…

Farber, Grace; Legg, Alison Slinskey – Science Teacher, 2018
The Bold Fold, which is presented in this article, is a 45-minute activity in which students create a protein model while learning the processes of transcription, translation, protein folding, and delivery, which are often difficult to understand and have led to common misconceptions (Wright, Fisk, and Newman 2014). This activity has been used…

Mulvey, Bridget – Science Teacher, 2018
Minerals are commonly taught in ways that emphasize mineral identification for its own sake or maybe to help identify rocks. But how do minerals fit in with other science content taught? The author uses mineral formulas to help Earth science students wonder about the connection between elements, compounds, mixtures, minerals, and mineral formulas.…

Nageotte, Nichole; Buck, Gayle; Kirk, Holly – Science Teacher, 2018
Imagine saving just one of the 23,000 species threatened with extinction. Students studying endangered species in a general life science course faced the decision of which species to save as a summative assignment in a unit on scientific explanation and argumentation. They used the claim, evidence, and reasoning (CER) framework in which students…

Pleasants, Jacob – Science Teacher, 2018
In classroom science laboratories, unlike a real science laboratory, the teacher can guide students away from potential dead ends and toward data that are most likely to result in accurate conclusions. Sometimes, though, allowing students to pursue dead ends and to collect "bad" data can provide especially rich learning opportunities.…

Wilson, Nina; Dashiell, Shelbie; McMaster, Nicole; Bohland, Cindy; Schmale, David G., III – Science Teacher, 2018
Approximately 1 billion metric tons of food are lost each year due to mycotoxins (FAO 2013), secondary metabolites produced by fungi (Marin et al. 2013) that contaminate crops (Placinta, D'Mello, and MacDonald 1999) and threaten the health of domestic animals and humans (Sobrova et al. 2010). The fungus "Fusarium graminearum" produces…

Chao, Jie; Xie, Charles; Massicotte, Joyce; Schimpf, Corey; Lockwood, Jeff; Huang, Xudong; Beaulieu, Craig – Science Teacher, 2018
As solar energy becomes increasingly affordable, many schools are considering installing new solar power systems. In this article, the authors present Solarize Your School, an engineering project that gives students the opportunity to design and evaluate solar power solutions for their own schools. This STEM project requires students to learn and…
