That's a ton of trash! Measure the amount of garbage generated in the classroom in order to make estimates about the waste produced by the entire school and all schools in the state. This eye-opening exercise leads into a discussion about different ways for reducing trash. For third graders, measure trash weight to the nearest pound, but for olders students, use this as an opportunity to practice multiplying fractions and decimals. A great Earth Day activity that connects math and environmental studies in a meaningful context.
