Simple tests and experiments

Perform simple tests and use observations and ideas to suggest answers to questions

Lesson

Set out your lesson

Practise the bounded task in Simple tests and experiments; see exact limits before inferring broader coverage.

Before teaching

Use this short check, then start teaching.

Activity

Make a prediction and notice wet/dry; an adult handles the water.

Policy

Exact directed source edges retained; earlier authorship is not learner attainment.

Printer, credit, and teaching notes

Exact directed source edges retained; earlier authorship is not learner attainment.

Materials

  • These supplied stage cards

  • Scrap paper and pencil; oral/pointing response where appropriate

  • Two different paper materials cut/torn to equal squares, spare scrap, clean room-temperature water, dropper or consistent small spoon, tray, adult supervision. If unavailable, mark planning only.

Sequence

  • Read readiness and decide on support without treating prerequisite authoring as learner readiness.

  • Open Show first and explain its model.

  • Use Guided Try with support and its separate adult key.

  • Close Show and guided keys before Try, unless this Try is explicitly supported.

  • Reflect on an actual attempt, including help used.

No Printer

Use the supplied screen cards; copying the exact task to paper is optional, not required.

Privacy

Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view.

Teaching limits and safe use

These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.

  • Requires real supervised observation; without materials, planning only, not a performed experiment. Drop counts are approximate, not volume measurements.

Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Students supports Simple tests and experiments. An adult previews and guides; this is a learning page, not a scored quiz.

Free educational page, no sign-in required for the tested path.

Before you open

Ask the learner one fact they learned and one question they still have.

Opening this link does not save learning or assess mastery.

Check understanding

  • Carry out a simple test with one thing changing at a time
  • Observe what happens and describe the result
  • Use the result to suggest an answer to the original question
“Can your child do a simple experiment — like testing which paper towel absorbs the most water — and use what they find out to answer the question?”
