Drawing conclusions from evidence (age 9+)
Report and present findings including conclusions, causal relationships, explanations, and a degree of trust in results using oral and written forms
Lesson
Set out your lesson
“Separate observations, explanation and trust. A fair test can support a causal explanation, but a few imperfect trials do not prove a universal rule. Repeats check consistency, not every error. Safety: Low indoor drops only, clear floor, no furniture climbing or throws. Stop: End after three trials and the report. No higher drops, fans or added weights.”
Bring to the table
- Two equal paper sheets
- Ruler, paper and pencil
- Adult partner and clear floor
Extra for the adult
Worked example. Illustrative results: crumpled first, crumpled first, uncertain; one release may have been unequal. Answer: changing shape may have affected landing order, supported by the two clear trials, but trust is limited by the uncertain trial and release error. These data do not prove an exact fall-time difference.
Optional challenge. Explain why three repeats of the same biased release would not remove that bias.
What to notice. Keep all trial records and the report. Note unclear releases and adult help.

Check understanding
- Present findings clearly in written and oral form with appropriate scientific vocabulary
- Identify causal relationships (X caused Y because...) supported by evidence
- Discuss the degree of trust in results, considering sample size, repeat readings, and possible errors
“Can your child write up or present their experiment results, explain what caused what, and discuss how confident they are in their findings?”
