Dear Bloggers,

The students made a ‘Measuring Car’ with a dial on the back so they  could record how far the cars travelled.  The gearing setup used a worm gear to slow down the hand of the dial so, like clock hands, it would move slowly allowing students to make and record their measurements.  The car was then rolled down 2 slopes (15cm and 25cm high respectively) from 50cm and 90cm down the ramp.  Students predicted what number their dial would read and then tested their predictions.  The pupils’ found over time as their experiences built their predictions became more accurate.

 

Thanks for calling by
