Identifying rocks Information sheet Basalt Sandstone Mudstone Granite A dark rock made from lava. Mostly black but weathers to a yellow-brown colour It is made from compressed sand. It is often a yellow colour with a loose, grainy surface. It is made from clays and mud. Often brown-grey in colour and may have cracks present. Granite is made from cooled magma. It is often light in colour and can contain crystals seen with the naked eye. Slate Shale Limestone Marble Slate is made from heated mudstone and shale. Mostly grey with speckles or streaks of gradient. The rock formed by compressing mud. Made up of layers and can be many different colours. A grey rock made from shells & coral. It may contain fossils or imprints. It is made from re-crystallisation of limestone. Often light in colour and sometimes with a shimmery surface. © www.teachitscience.co.uk 2015 17047 Page 1 of 3 Identifying rocks Key Does it fizz when acid is added? Use the key to identify the rock samples YES NO Does it produce bubbles when it’s put in water? Can you scratch it with a nail? YES NO YES NO limestone marble Does it produce bubbles when it’s put in water? Does the rock contain crystals? YES NO YES NO granite basalt sandstone Can you brush any sediment from it? YES NO mudstone or shale © www.teachitscience.co.uk 2015 17047 slate Page 2 of 3 Identifying rocks Teaching notes Cut the information sheet up and ask students to match the descriptions to the pictures. Ask them to decide which type of rock each example is e.g. igneous, metamorphic or sedimentary. Use the key as part of a practical to identify rocks. Provide groups with samples of each type of rock, hydrochloric acid, iron nails, magnifying glasses, pipettes, white tiles and goggles. Carry out a risk assessment for the activity with your group.
