Discovering Sound Matters
We have lots of favorite experiments and demonstrations that we love to play with... and this is absolutely one of them! Who knew that sound has physical matter?!? Now, before I go on, a word of caution--this project is for older kids only, since the experiment involves using a candle.
How We Did It
Our oats container wasn't quite empty yet, but we couldn't wait any longer! We dumped the rest of the oats in a (temporary) bowl so we could play with science.
Madeleine drew a penny-sized hole on our lid, near the center. (We figured we'd just put a piece of tape over it when we returned our oats!)
I had the job of cutting the hole.
Maddie put the lid on snugly....
We were using a tea light, so we needed a small bowl to lift our candle up to the height of the hole in our lid.
I lit the candle, and Maddie got ready....
We put the bowl and candle next to the oats box, and then Maddie held onto the box with one hand, and gave the bottom a sharp 'Tap!' with the other. The vibration (sound waves) traveled through the container, and out the small hole.... and put out the candle! Wow!! Let's do that again! And now again!....
