Use the link above, which will take you to a lesson on how sound travels. It will help us to understand how we can reduce the level of volume and when we might need to do this.
Can you design a fair test to decide which materials would be best to muffle sounds?
What would be the variables in this test? Which variable would you want to change and which would we need to keep the same to ensure a fair test?
There is a planning sheet linked in the lesson, which you can print.
I would love to see your fair test design!
