Our Newest Mineral Kit: Mineral Observation, Hardness & Streak Testing Kit

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.
