Look closely at rocks
1 · Learn
Rocks can look and feel different. Some show visible grains or crystals. Some have layers; others do not. Colour alone rarely tells us everything about a rock.
Choose a property to compare, such as grain size or whether water soaks into a safe sample. Keep observations separate from a guess about its name.
2 · Worked example
I observe large visible grains in one sample and no easily visible grains in another. I record those differences before using a guide to identify them.
3 · Your turn
Two rocks are grey. Does that prove they are the same rock type? Why?
Check your answer
No. They may have different grains, layers or other properties even when their colour is similar.
4 · Apply your learning
Use safe classroom rock samples and a hand lens. Draw and label observable differences.
Adult guidance and safety
No hammering, dust-making, licking or acid tests. Wash hands and avoid unknown or sharp samples.

My observation notebook
With an adult, look at a safe real example or a checked photograph. Name the example and say which you used. Record what you actually notice. Do not taste plants or materials, approach unknown animals or invent missing observations.
Ask your teacher for support with the method and recording. A prediction is what you think might happen; an observation is what you actually see, hear or feel safely.
Keep your notebook: use Download notebook before leaving. Nothing is sent to the website or saved to your account. Reopen the downloaded notebook here to add another day's record. Do not include names, addresses or other private information.
