A dish can be used to draw a circle. Flourescent chemicals became glow sticks or non- burning flares. You can take the lead from a pencil, and you have a stick with a hole in it. If you pass a thread through the stick you can hang something from it. You can remove the bill from a baseball cap and make a beanie.

What materials can you use which are recycled. Can you use a plastic bottle instead of making a new plastic shape.

Have each child read one problem from their paper.
