P3McE Space Investigation

Space Investigation

Primary Three have been investigating to see which material would be the best to block out sounds in a space rocket.

They want to make soundproof headphones for the astronauts.

They wrapped a clock in different materials and counted the number of layers needed to block the tick of the clock.

They discovered that cotton wool was the best material  to make the earphones with because it was so thick.
