Presentation
Danny empties two bags of garbage onto the floor.
Jenny: That’s a lot of garbage! Can I help you sort it
Danny: Yes, please. Let’s put the glass here, the metal here, the plastic here and the paper here.
(After they sort the garbage, Danny and Jenny are surprised. Almost all of it can be reused or recycled! They need to throw away only one small bag of garbage! )
Jenny: People throw too much away. They shouldn’t waste so much!
Danny: That’s right. Look! There is more paper than plastic. And there is less metal than plastic. There is the least amount of glass.
Jenny: And the most amount is paper. It is a waste to use paper only on one side.
Danny: Hey! I found a toy car. One of the wheels is broken. I’ll take this car home and clean it. Then I’ll use some glue to fix the broken wheel. When I finish fixing this car, I will give it to my little cousin, Debbie.
Jenny: Nobody should throw away a toy like this. It can be fixed. It’s not right to waste things. Look at all of the glass. It can all be recycled and made into new glass.
Danny: A lot of glass is broken. It’s dangerous to leave broken glass on the ground. Once, I cut my foot on a piece of broken glass.
Jenny: Litter can hurt people!
