Sound experiments

We placed grains of rice on the tin and hit the side of the tin with a stick.The grains jumped!We learned how sound travels in waves and creates vibrations.





We also used a tuning fork to show that sound travels through air.We struck the tuning fork and then placed it against a plastic object.The object moved back and forth due to the sound waves!


We also struck the tuning fork and placed it into a basin of water.The water splashed proving that sound moves through water!
