Year 4 - How is sound made?
Date: 27th Apr 2023 @ 2:52pm
Today, we learned how sound is made. We started the lesson by closing our eyes and listening for a sound to be made. We then pointed in the direction of the sound. Next, we discussed that we hear sound through our ears. So how does it get there? Using a tuning fork, we hit it against the table and dipped it in some water. Straight away we could feel tuning fork vibrating in our hands and see the tuning fork vibrating in the water. Using the scientific vocabulary on the board we discussed what was going on. Then we made string telephones. We predicted that we would be able to hear our partner because the vibrations would travel as sound waves down the string. We then used rice on a drum and beat the drum to further see and show vibrations from a sound source (this time the beater).
