Building Week Part 2: Strong Shapes. I discovered this through pinterest and I really like the idea of using the three basic shapes – triangle, circle, square – to test books on. Obviously it might be easier for us to use actual masses rather than books.
I think it could be quite good, not only as a fun activity for younger children as the original blog says, but also a basic preliminary in an engineering lesson. Before building the bridge, test these shapes. Or before building the tower, which shape will be strongest? And then predict, test and use the knowledge on the actual task.
You would have to keep the three shapes to strict rules – one piece of paper per shape. How can you stick it together? And then how do you place the masses/books on it?
It could even then evolve into building a structure with these shapes in what shape? For example, do you put three triangles in a triangle to hold masses or would 4 squares in a square work best. Vary this and increase the experiments!
