This experiment demonstrates a simple way for kids to learn about sounds, particularly, how sound makes movements. For this experiment, you will need the following:

1. Bowl
2. Plastic wrap (e.g., Saran wrap)
3. Rice
4. Metal tray
5. Metal spoon
It may be rather difficult to do this experiment alone for little kids, so it is recommended that adults take part in the performance of this experiment. Aya has to enlist the help of her Tita Lai to do this experiment.

Stretch the plastic wrap over the bowl as tightly as possible.

Next, scatter grains of rice across the top of the plastic wrap.

Then, hold the metal tray as close as possible to the bowl. Hit the tray with the spoon to make a loud noise. And I mean really loud! Observe what happens to the rice.

Explanation: Hitting the tray with the spoon makes the air around it vibrate; when the sound waves reach the plastic wrap, they make it vibrate. This makes the rice grains move.
