4Red Science- To explore sound amplification

Today in Science we have looked at making sounds louder, we used different materials to make amplifiers, in order to test how loud we can make sounds. We have worked in teams to make our creations.

We swapped our creation with other teams to work on unfamiliar creation. Can we make sounds louder? and how?

There are different effects that sounds has on ears, different sounds on our ears too.

How can you improve your creation? and what have you learnt from swapping projects?


  1. We can make sounds louder. We can do this by creating different shapes with materials. I can improve my creation by making it more strong. I have learnt that different shapes can create different and louder sounds from swapping projects.
