Week Seven -- Cars

Use the materials below to build a car. No scissors! Then, see if you can make it roll down a ramp. If it rolls, measure how far it goes and send your pics and results!

4 sheets of paper
2 pencils
2 markers
scotch tape


And, for fun, read about these cars.

Note: If a challenge seems to easy, you can make it harder by limiting solution time to 10 minutes or 5 minutes.

As always, participants will be entered in our October giveaway.

Lastly, don't forget to check out some of the ongoing challenges in the right column. And, if you try one, send us some pictures!
