Band Rollers

 We had a very interesting visit from a scientist called Liz today. She helped us make'band rollers'. We had to think carefully about scientific things like friction, speed  and energy as well as using our hands to make our rollers. We had such fun racing them at the end of the session.

 Here we are racing the band rollers in the library.

 Concentrating hard and using the tools well.

 We also decorated the band roller wheels with patterns and watched how these changed as they moved.

 Here we are decorating our wheels.

 We had to mark quarters on the wheels so we knew where to put on the pins.

Everyone enjoyed this very much.
