California Academy of Sciences: Compost - A Scientific Investigation
California Academy of Sciences

In this two-part inquiry-based activity, students will practice using the scientific method while learning about decomposition, exploring how some types of garbage will decompose while others will not. Students can then go on to design their own experiment to test different variables affecting the rate of decomposition.
