Atmospheric scientists study the chemical composition of the atmosphere. More specifically, they look at how atmospheric gases, liquids, and solids interact both with each other and with the earth's surface. This helps people understand such phenomena as air pollution, ozone depletion, and climate change. Shawn Urbanski is a research physical scientist at the U.S. Forest Service’s Rocky Mountain Research Station in Missoula, Montana. He studies wildfire smoke chemistry and the impact of wildfire smoke on air quality.

Computer simulations have become essential to scientific investigation and engineering design, thanks to advances in mathematical modeling, game theory, and computing technology. Simulations now provide an indispensable tool for investigating the properties of natural and built systems in science, engineering, economics, and social science.

In the February 2019 issue we looked at teaching speed and velocity. Now we’re ready to tackle acceleration.

Teachers use simulations for student motivation, content learning, and engagement in science practices.

Games allow 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 me to “play” with my students in ways that other learning activities do not (Kirkland and O’Riordan 2010). I can be silly, competitive, cooperative, lenient, creative, and supportive alongside my students in a way that I cannot during lab activities, assessments, or even project work time.

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 online simulation to facilitate high school students’ accurate conceptions of the relationship between photosynthesis and cellular respiration in plants.
