Most people get these wrong and think the one of the left will light, but the one on the right will not. edit: or was it the other way around? I'm sure someone will correct me if I have it backwards.

Marked for later. This has me intrigued.

The left one will produce light if you use a strong enough cell!

An interesting project would be the study of G forces on cats. The study would qualitatively find a cats survivability threshold to G forces.

The testing apparatus would be a bucket (with lid) attached to a rope (two meters in length tied to the bucket with a figure 8 pass through knot).

Procedure:
1. Place living cat in bucket.
2. Cover lid.
3. Grab hold of rope end opposite of bucket.
4. Begin swinging bucket in a large circular orbit above head.
5. Stop swinging, and lower bucket.
6. Open bucket lid slightly and check for signs of life.
7. If cat is still alive, repeat steps 4-6. Be sure to increase velocity of orbit.

This can also be an interactive project, as you can encourage the judges to participate.

Wouldn't that be testing the effect of centripetal force on a cat? Might as well tie its tail to a ceiling fan.

Same smell. Also, tying its tail to a ceiling fan would be cruel. Cats tails are extremely sensitive.

Volcano!!!!!

That's what I did in grade 3, except it was a 'water volcano'. About 2 or 3 other of my classmates. At least the entire class discovered that heat rises...ya.
