P5Y were experimenting with sound. We wanted to see how sound travels through solids, liquids and gases. This is what we noticed:
Melissa: I saw the ruler was moving quickly.
Wil: When I scratched the balloon I heard a squeaky noise.
Mackenzie: I felt a vibration when I made a humming noise.
Thomas: I saw the rice going up and down on top of the drum.
Alix: I saw the strings vibrating.
Fraser: I saw the water vibrate when the tuning fork went in the water.
