We have had great fun designing and building our own marble runs!
We began by investigating different types of free-standing structure. We looked at what made them strong and stable. We then applied this knowledge to building the tallest free-standing structure we could from construction kits.
We also had a go at building marble runs using kits to investigate what made a good marble run. We looked at the speed the marble traveled at, the smoothness of the journey and the aesthetics of the design.
After some focused practical tasks - looking at cutting, joining and specific elements of a marble run, we designed and made our own marble runs in groups. We tested and evaluated them to finish.
