Thinking like a scientist
1. Write a prediction
A good prediction says what you think will happen and why. Writing it first stops you changing your mind after you see the result.
2. Keep it fair
Change one thing at a time and keep other conditions as similar as you can. This helps you investigate a possible cause, but one trial does not prove it.
3. Record what you see
Draw or measure every day. A surprising result is not a failure; it is a new question to explore.
Do every experiment with a grown-up. Wash your hands afterwards, never taste materials and watch wildlife without touching it.
Parents & TeachersA surprising result is worth checking
Does one experiment prove your explanation is right?
No. An observation can support an explanation without proving it is the only possible one. Repeat a trial, record unexpected results and consider other causes. A home experiment is a useful starting point, not a substitute for a large study.
1. Predict and observe separately
Before starting, say what you expect and why. Afterwards, record what you actually saw or measured. Keep both records even if the result differs from your prediction.
2. Check the comparison
Ask whether you changed more than one thing. Different seed types, container sizes or light levels could each affect growth. A careful comparison makes explanations easier to assess, but cannot remove every uncertainty.
3. Repeat before a big claim
Try again with safe materials and adult supervision. If results differ, keep the differences in your record. Do not erase an unusual result simply to make the experiment look successful.
