Using evidence to answer questions
Identify differences, similarities, or changes related to scientific ideas and use straightforward scientific evidence to answer questions or support findings
Lesson
Set out your lesson
“Use a specific result to support an answer. Look for a pattern, including similarities and differences. If results vary, say so. Evidence from these paper pieces cannot tell us how every bridge behaves. Safety: Stable floor setup and light wooden pencil only. Stop if supports move. Stop: End after six light-load checks. Do not add trials simply to obtain the expected answer.”
Bring to the table
- One wooden pencil, paper and ruler
- Two equal sheets and two stable books
Extra for the adult
Worked example. Illustrative results: A holds 0 times out of 3, B holds 2 times out of 3. Answer: B held more often in this set, supported by 2 successful trials compared with none. The one failure means B was not always successful; do not replace 2 with 3.
Optional challenge. Explain why both designs failing would still be useful evidence for this load and gap.
What to notice. Keep the full table and evidence sentence. Note assisted counting, folding and adult sentence suggestions.

Check understanding
- Identify at least one pattern (similarity, difference, or trend) in a set of scientific data
- Explain how the pattern relates to the scientific idea being investigated
- Use specific data points as evidence when answering a scientific question
“When your child looks at their experiment results, can they spot patterns — like things that are similar, different, or changing — and use the evidence to back up their answer?”
