The Mohs hardness scale was invented by Friedrich Mohs in 1812, and has been a useful tool for geologists to determine the identity of different minerals. With this kit, students will become familiar with the Mohs hardness scale and how to perform the hardness test, allowing them to develop vital skills that will help them throughout their studies in earth science. This kit also provides students an opportunity to go out into their local environment to investigate the relative hardness of the minerals around them. Kit contains an Instruction Manual and enough materials for 2 groups of students.
