Composting is the process that turns vegetable scraps and other organic materials into lovely soil. Carbon and nitrogen are essential ingredients in your compost. Carbon-rich materials are called brown materials, and nitrogen-rich materials are called green materials. In this experiment, you’ll use newspaper for carbon and lettuce for nitrogen. Your goal is to see what mixture of carbon and nitrogen-rich ingredients is best at composting.
What mixture of carbon and nitrogen-rich ingredients is the best at composting?
