Do sound waves travel under water? That's what the Cycle 2 investigated yesterday during Science class. Each group had a hydrophone, which was a 2 litre pop bottle cut off at the base. They then put the pop bottle in a tub of water and each partner banged 2 rocks under the water to see if they could hear the noise of the rocks banging. They discovered that yes, sound waves do travel under water. Actually the noise was louder under water!
Cool scientists!Are there any winter experiments your class would like to come and do for the Prek-k class?
