1. 1

   Pendulum count

   Tie a key or a spoon to a piece of string and tape the string to the edge of a table so it hangs down. Pull it a little to the side, let go and count the swings in 15 seconds. Now make the string half as long. More swings or fewer?

2. 2

   Cup telephone

   A grown-up pokes a small hole in the bottom of two paper cups. Thread a long string through and knot it inside. Pull the string tight and talk.

3. 3

   Bean in a bag

   Fold a damp paper towel into a zip bag with a dry bean and tape it to a window. Check every day. Which way do the roots grow?

4. 4

   Ruler twang

   Hold a ruler on a table edge with most of it hanging off and twang the end. Slide more onto the table and twang again. How does the sound change?

Safety first: With a grown-up. No tasting.
