Over the half term, we have been looking at what creates a stable structure. We found that a stable structure has a wide base, low height and a flat surface. First we tested 3 different shapes (cuboid, triangular prism and a cylinder). We found that the cylinder was the most stable and could hold the most weight. This is because it doesn’t have any corners. The children were set a challenge to plan and design a chair for Baby Bear from the story Goldilocks and the three bears.
Next, we made a plan by designing our chair thinking carefully about the chairs for baby bear will look like. How many legs will it have? What shape will the seat be? What will the back look like? What materials/resources will you need?
When we had made our chairs, we tested the stability by placing different weighted bears onto the chairs.
Well done Year 1 and 2. You worked well together to create your own chairs for baby bear.
Help at home:
What 3 things make a stable structure?
Would you do anything differently if you were to make the chair again?
