Collect ahead an assortment of garbage and recycling. Choose some items that make good discussions afterwards (i.e., varying plastic, paper, diapers, batteries, electronics, plastic toys, bags,milk jugs, juice-boxes, cans, bottles, re-usable items, compost items, paper, styrofoam). Research ahead recycling regulations for your municipality. Find out which number of plastic are accepted and where to dispose of hazardous and electronic items. Set up bins at a distance away from the teams. You will need separate bins to sort such as one for paper, newsprint, returnables, other recyclables, garbage and compost. Give each team an equal pile of recyclables/garbage. Children race to fill up the bins. Afterwards discuss what has bin put in each bin.
