QUESTION 1
What is the difference between reuse and recycle?
Reuse means using the same thing again as it is; recycle means making it into something brand new.
QUESTION 2
Why is reducing the best first step?
If you use less in the first place, you make less waste, so there is nothing to throw away, reuse, or recycle.
QUESTION 3
Name one thing you can recycle.
For example, paper, a glass jar, an aluminum can, or a plastic bottle.

Create: my Earth plan.

Have students pick one of the R's to try at home, write one thing they will do, and draw it in action, so caring for the Earth becomes a real habit. A printable reduce-reuse-recycle worksheet is in the Science library.
