As part of science, design & technology J2 have been studying the strength of 2D and 3D shapes. Their challenge was to build a bridge made from paper and art straws. It was to span 30cm and carry as much as possible. They discovered triangles and cylinders were extremely strong. Abby F won the class challenge. Her bridge took 1.6kg before it gave out!

Mrs Roach judges the challenge!
