Fun and Discoveries Galore

Wow, look what I discovered while I was researching earthworms for our 4th grade worm farms.  What a great site to explore.  You could spend all your time here so plan accordingly.

Let me know what you discover.

Here’s a sample of something simple and fun I found:

Science Fun. All Charged Up.  Demonstrate the “shocking” effects of static electricity.

  • A comb
  • A water faucet


Comb your hair on a dry day. Hold the comb near a thin trickle of water from the faucet. The water should bend toward the comb.


Running a comb through your hair creates friction that moves electrons from your hair to the comb, charging the comb with static electricity. The comb now has a negative charge. When you move the comb near the water, its negative charge pushes away some of the negative charge in the water, leaving the water with a positive charge. Positive and negative charges attract, so the water bends toward the comb.
