Students can use an O2 Gas Sensor to measure the amount of O2 produced when H2O2 is broken down by the enzyme catalase at different concentrations, pH values, and temperatures. They will also measure the enzyme's initial reaction rates.

In this activity, students' will record the x- and y-coordinates of a rod moving in a figure-eight pattern. They will then use the recorded motion information to separately model the x- and y-motion as a function of time. They will plot...
