Testing materials for hardness

As part of our Science curriculum, we have been testing materials to compare how hard they are. Which would be the best for making a kitchen work top?

We used a nail to scratch each material as a test for hardness. We agreed to have the same person in each group scratching each material to keep the test fair. Different groups decided on their own method for recording results. Many of us devised our own rating key to record accurate results.
