Testing strength of materials in Science

As part of our topic on Materials, class 2 had the challenge of making 6 strips of crepe paper as strong as possible, so that they could hold a bag of shopping without it breaking. The children worked in groups to investigate ways of making their paper stronger without using any other materials.

Some groups shortened their ‘ropes’, whilst others rolled the strips before plaiting or twisting them. We then tested them with a carrier bag and added weights, testing how much weight the ropes could hold.
