Some of the class had great fun making 3D shapes in the last two weeks. As a class we made a very large shape that has squares, triangles and pentagons as faces and has 60 vertices. The plans we used to create this called it a windball. We used some joiners from a construction set Mrs S had found called Makedo.
When we took our shape outside and put it on the grass. It did not roll at all. We decided that the cardboard was not rigid enough and the tufts of grass were too tall and caught in the open sections of the shape. When we put it in the asphalt area the wind blew it along very well.
When some of our class was competing in a sporting event the rest us made some 3D shapes using straws and pipe cleaners. The pipe cleaners were cut and bent to use as joins. We tried making a cube, tetrahedron, square pyramid and an octahedron. Just before we packed up Mrs S gave us 10 minutes to create the tallest structure we could. It had to be free-standing and we could only use straws and pipe cleaners. The tallest structure measured 86 centimetres.
