Sound and Energy Science

Third and fourth graders from Ms. Palmer and Mr. Houchens's classes investigated sound dampening materials as part of their study on energy. 

Sound is a form of energy. Sound is a vibrations that travels in waves to our ears. Sound vibrations can be so powerful that they can make glass break! Some materials can dampen this vibration by absorbing the waves, while others, like a tile shower, allow the sound waves to bounce off and travel farther because the waves are reflected.
This happens because as sound waves move through a material, sound energy can be absorbed. Students conducted investigations into which materials absorb sound energy. Different materials yield different results, because sound energy transfers differently through varied materials.
