You could blindfold them and spin them around, or you could have them ride a merry-go-round, or twist them around in a swing, and let the swing turn back around to its normal position. Sound Wave Activities Once a sound wave enters your ear canal and vibrates your eardrum, your brain interprets the vibrations as sound. Play around with the water levels in each jar and experiment with pitch! How does sound travel long distances? It also sounds deeper. Ask your child to explain what happens to the sound the shorter a straw is cut, and create double pan flutes to make harmonies to further explore how length alters the pitch. elementary school science teaching resources, Initial Sound Recognition Worksheets (uppercase letters) Complete Set AZ, Small shoebox or gift box (no lid required). As students learn about pitch, frequency, and how sound travels, they can also investigate the typical frequency range for human hearing compared to other animals and ask questions about ultrasonic hearing, echolocation by animals in water (like dolphins) and out of water (like bats), the speed of sound (in various mediums), what sound energy is, and what it means for something to be supersonic or to create a "sonic boom.".
