Students hypothesize about the amount of carbon dioxide in soda bottles. In this chemistry activity, students design an experiment to solve the problem. They share findings in class.

High schoolers separate food coloring using liquid chromatography. In this chemistry instructional activity, students explain the effects of different solvents on the rate of separation.

Students design an appropriate and usable storyboard and then create a claymation video. They take digital photographs frame by frame, then assemble the stop-motion movie using video software.

Students investigate friction between different surfaces. In this physics lesson, students research biomaterials that can reduce friction. They calculate efficiency using a mathematical formula.

Students explain the process of polymerization. In this chemistry lesson, students produce carboxylesterase in the lab. They test its effectiveness in removing the by-product odor.

Learners explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.
