A blank data table asks students to record six properties for each rock or mineral sample they test: colour, lustre, streak, transparency, hardness, and whether the sample is magnetic. After completing the table, four short-answer questions have students identify the softest and hardest minerals among their own tested samples and explain how they know, then name the softest and hardest minerals known in the world for comparison. The table itself supplies no pre-filled sample names or property data, so completing it requires physical rock or mineral specimens to test rather than reading.
