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…

Hewitt, Paul G. – Science Teacher, 2020
An economy that grows is good. Growth in income is certainly good. In general, growth is seen as a good thing. A global pandemic challenges this notion. Let's be careful of what we wish for- especially if growth is "exponential." This article describes exponential growth and doubling time, and shows how these concepts can be related to…

Ellingson, Charlene; Dubinsky, Janet M. – Science Teacher, 2020
Effective science instruction requires knowledge of subject matter and scientific practices (Next Generation Science Standards (NGSS), 2013), as well as the context within which learning occurs (Anthony, Hunter and Hunter 2014). For science teachers, there is often a tension between the efficiency of lecture and student engagement that comes with…

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…

Rock, Carly A.; Whitworth, Brooke A. – Science Teacher, 2021
At the core of an effective model-based inquiry (MBI) unit is a scientifically rich, complex phenomenon that serves as the reason for engagement and drives student sensemaking and investigations throughout the unit. Engaging in iterative attempts to explain phenomena over the course of an MBI unit allows the opportunity for students to construct…

Haroldson, Rachelle – Science Teacher, 2019
Teaching the periodic table is a central part of chemistry. This might involve memorizing the symbols of the elements, learning about the properties of the families, or understanding its general organization. This year, The International Year of the Periodic Table, marks its 150th anniversary, and represents a good opportunity to highlight its…

McKinney, Daniel – Science Teacher, 2020
Teaching the tools and concepts associated with modern physics can often be a daunting and difficult task for secondary science teachers. Classical physics is often perceived as intimidating and complex in its own right. Modern physics addressing quantum phenomena where Newtonian laws break down is even more abstract for learners. However,…

Park, Byung-Yeol; Rodriguez, Laura; Campbell, Todd – Science Teacher, 2019
Cultivating students' scientific knowledge and developing their capability in scientific inquiry depends on a teacher's ability to use existing resources to design rich learning opportunities. Designing such experiences is not easy, and is particularly challenging for new teachers who have little experience making decisions about the best way to…

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.…

Bhattacharya, Devarati; Steward, Kimberly Carroll; Chandler, Mark; Forbes, Cory – Science Teacher, 2020
To enhance teaching and learning about Earth's climate and global climate change (GCC) in secondary science classrooms, the authors are engaged in a four-year, National Science Foundation (NSF)-funded project to develop, implement, and evaluate a new four-week curriculum module grounded in the use of a data-driven, computer-based climate modeling…

Souders, Hannah – Science Teacher, 2018
Protein synthesis, involving such abstract concepts as "DNA," "RNA," "transcription," and "translation," is one of many biological processes too small to be seen by the naked eye. This combination of scientific jargon and sub-microscopic elements can make biology seem overwhelming to any student--but…

Inouye, Martha; Houseal, Ana; Gunshenan, Clare – Science Teacher, 2020
Recent research on science teaching and learning defines science as both a body of knowledge and a process (NRC 2007); it is the integration of science content, practices, and core ideas (NRC 2012). It would follow that science learning should parallel what science is and how it is done; students should not be just consumers of scientific…

Hewitt, Paul G. – Science Teacher, 2017
When teaching how "tension" and "compression" relate to geometrical structures such as bridges, arches, and domes, The author shows a picture of the Notre Dame Cathedral in Paris, completed in the 14th century, and presents a lesson on using the curve called a catenary to explain how he teaches about tension and compression…

Peel, Amanda; Rockett, Jordan; Friedrichsen, Patricia; Zangori, Laura; Elmy, Clayton; Wagner, Brandon – Science Teacher, 2020
Vaping (the use of an e-cigarette) is a common practice among teenagers; 26.7% of high school students report vaping in the last 30 days (Johnston, Miech, O'Malley, Bachman, Schulenberg, and Patrick 2019), making this issue highly relevant. In order to make an informed decision about the use of e-cigarettes, students need to understand the impacts…

Kinslow, Andrew T.; Sadler, Troy D. – Science Teacher, 2018
Teaching socio-scientific issues (SSIs) allows students to explore science ideas and practices intertwined with complex social phenomena, which can promote significant growth in critical thinking. Sadler, Barab, and Scott (2007) suggested specific critical thinking competencies associated with the negotiation of SSIs that capture the complexities…
