Let your class SEE sound with this exciting, investigation-packed science lesson for Year 4. Children discover that every sound — from drums to their own voices — is made by vibrations, then follow a sound wave’s journey through the air, into the ear and all the way to the brain. Amazing-fact slides explore how whales sing through oceans, why solids carry sound faster than air, and why space is completely silent. Two full hands-on investigations are built in: a “sound cannon” where banging a tray makes rice leap off a drum skin, and elastic band guitars for predicting and testing pitch like real scientists. Clear, visual explanations nail the tricky difference between volume (size of vibration) and pitch (speed of vibration) with a memorable golden rule. A partner quiz completes the hour and checks understanding. Colourful, child-friendly slides with a cheerful cartoon guide make this a true open-and-teach resource. Fully matched to the Year 4 National Curriculum for sound.
