Today with Let's Talk Science we did some great experiments to further understand the properties of light and sound. Students tested the reflective properties of different materials and discovered how light refracts.
Finally, they each got to create a "sound sandwich" instrument as they learned about vibration and pitch. Moving the straws changes the pitch, and the sound is caused by the vibration of the rubber band. I hope your ears are okay! :)
