In our last two Science lessons, Year 4 have been learning about how sound is produced by vibrations. We have carried out some simple investigations to see and feel sound vibrations. We also looked at how to change the speed of vibrations and explored how this effects the frequency of a sound.
The investigations we tried were:
- Putting our fingers on our throat whilst talking
- Speaking to our partner through a balloon
- Putting rice on a drum and seeing how the rice moved
- Changing the length of a ruler before letting go
Maybe you could try some of these at home!
