Be a Food Waste Warrior

Three 30- to 45-minute periods, which includes time for one food waste audit session at lunchtime (schools may choose to audit one day or multiple days)

“Be a Food Waste Warrior” is a three-part science and math lesson that can be adjusted in complexity depending on grade level. It includes food waste audit log sheets, discussion questions, a companion PowerPoint, and additional teacher resources and materials.

Students will learn about the ways in which food impacts the environment by recording data from a student food waste audit during their lunch period.The audit will engage basic science and math skills to (1) convert food waste weights to water used and GHGs emitted, and (2) calculate the difference in GHG emissions depending on whether food waste is landfilled or composted. Participating students will ultimately understand how to reduce food waste and why reducing food waste is important to conserving natural resources and wildlife habitat.
