Year 5 have been looking at different types of materials and how they can show different levels of hardness. To test our theories, we used a sharp nail to scratch a range of different materials, before using our magnifying glass to check for how much of a mark or dent we had made. Unsurprisingly, paper didn't stand up well to the scratch test, but the stones were very hard! We concluded that it was not a good idea to make a bridge from paper for this reason!
