We are thrilled to introduce our latest mineral kit, the Mineral Observation, Hardness and Streak Testing Kit. This new kit will teach your kids to make scientific observations, test the hardness of minerals using the Mohs Scale and the using streak plates, and compare the properties of the samples in the kit.

Question: Based on Mohs hardness scale an unknown mineral scratched Apatite. It also scratches a steel knife blade but it cannot scratch quartz. What is the mineral’s hardness?
