Technology in Year 4

What shape will  give a structure the most stability? This was the question Year 4 spent time investigating. We began with a simple piece of paper and noticed that, by changing its shape into a cylinder we could increase the strength and stability of the paper. We tried a series of smaller cylinders (straws) arranged into a larger cylinder. After that, we looked at the strength of squares and triangles using a range of materials including lollipop sticks, match sticks and finally pieces of doweling. On deciding that a triangle was the most effective we went on to create larger shapes that we could fit inside! Great learning and great fun!
