Trash Talkin'

In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste. Learners make predictions on the types of trash that they will collect in a week and sort the trash they collect into categories (food, paper, plastic, etc.) and subcategories (re-useable, recyclable, and non-recyclable). Learners calculate the total mass of a group of items, explain how accumulating solid waste affects the environment, and investigate the attitudes about solid waste in developed and undeveloped countries.
