Compost Science: Weekly Science Project Idea and Home Science Activity Spotlight

How does the rate of decomposition compare for different items and materials? Set up an indoor composter to find out!

In this week's spotlight: a pair of environmental science projects that help guide families in an investigation of different biodegradable and compostable items. Do all environmentally-friendly items decompose at the same rate or as completely? With a homemade indoor composter, you and your students can run your own experiment and see what happens.
