Not all spring toys are equal!

8S measured the energy in spring toys today. 

Are all spring toys equal?

First select your toy

Then find its mass

Prime the toy by pushing it down and wait. 

Its difficult to see how high they jump so the pupils used slopro to film the jump. 

This makes it more accurate. 

Each toy was measured more than once to check reliability. 

Then the footage needs reviewing so the jump height can be recorded. 

Analysis of results tomorrow.
