P1/2 had a go at making working turntables to allow cars and boats to pass over/through their “canals”.
What did they do?
Using models and toys as inspiration, the children tried to think of ways to open and close a canal bridge and allow traffic through…they created a turntable using a combination of k-nex cogs and spindles (and with some extra kit from Mr. McConville) and cardboard.
They found that the turntable was very hard to turn and thought about how to make it easier – some of them thought that placing the turntable on rollers might help. That was still tricky, but they did manage to turn the table themselves with the first cog, then they took the truck across the top and the boat underneath.
Here are some of our pictures…
