How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!

Students explore the properties of enzymes. In this chemical reaction lesson, students explore enzymes through a Web-quest and investigative study. Students will collect and summarize data and create a class presentation. This lesson is...

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Fourth graders model the activity of an enzyme acting on a substrate and observe relationships. Have students place toothpicks in a pile. One member of the team should break as many toothpicks as possible, in 10 seconds.

In this biology lab, students use pineapple juice as an enzyme, and jello as a substrate to illustrate an enzyme/substrate complex.
