Year 5 have been investigating the force of friction.
Miss Whipps brought in 3 tyres from various bicycles with different types of tread
for the children to test. They held the tyre and had to get it rotating at a
certain speed. Then, they held different materials against the tyre, timing how
long it took for the wheel to completely stop moving. The children
evaluated the effectiveness of their investigation, highlighting areas they
could improve in order to increase the accuracy of their results.
