Read with an adult. Take your time. You can say, point, draw or write your answer.
1 Let's look together
We can put things into groups using one rule. Our rule might be 'bendy' or 'not bendy'.
Test each safe sample gently. Put it in the group that matches what you observe. Tell someone the rule you used.
BendyNot bendyTest → decide → explain
Look, point and talk with your adult.
2 Watch how I do it
My fabric sample bends. My wooden block does not bend in my gentle test. I put them into different groups.
3 Your turn
Can the same objects be sorted again using a different rule, such as shiny or dull?
Have a go before opening the answer.
Let's check together
Yes. A different rule may make different groups.
4 Try it away from the page
Sort four adult-chosen samples. Draw the groups and name the rule. Explain a sample that was hard to place.

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.
Tell your adult what you notice. They can help you write it. 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.

Explore and practise freely. Opening this lesson or using the writing pad does not save completion or a score.
Adult notes · prerequisites, safety and coverage
Do not force ambiguous observations into false certainty. Discuss differences in thickness and form; sorting is based on the actual samples.
Use real observations alongside the diagrams. Supervise practical work; never taste unknown materials or plants, handle unknown animals, or look at the Sun. Return to plants, weather and daylight throughout the year, not just once.
Compare and group materials using their properties.
Ask, observe, test, classify and record evidence with adult support.
