11. Learning Activity Metal Detective Discuss with your partner how we can work out whether a material is a metal or a non-metal. Then write down a minimum of three lines on how you would carry out your tests. Hint! Think about the properties of metals. How can you test to see whether a material has any of these properties. The scratch test can be used to find out if a material is a metal or a non-metal. By scratching the outside of the material you can see whether it is shinny or not on the inside.
