Mineral expert - identifying minerals using 'action' tests

In 'Be a mineral expert - 1' pupils were asked to identify a set of unknown minerals using the properties of colour, habit, lustre and cleavage that they could see. In today's activity 'Be a mineral expert - 2', they are asked to use the 'action' tests of streak, density, hardness and the acid test to further identify unknown minerals.
More minerals activities can be found on the ELI website.
