Activity 01
Pairs: Evidence Match-Up
Pupils pair circuit results cards with conclusion statements, justifying matches with data quotes. They swap one mismatched pair and explain revisions. Pairs present strongest evidence to class.
Evaluate whether our data actually answers our original question.
Facilitation TipDuring Evidence Match-Up, give each pair one incomplete conclusion card and one data card; they must match them before moving to the next set to build careful reading habits.
What to look forProvide students with a simple results table from a completed circuit experiment (e.g., bulb brightness with different numbers of cells). Ask them to write one sentence stating their conclusion and one sentence suggesting an improvement to the experiment.

Small Groups: Improvement Relay
Each group reviews their experiment poster, passes it to next group for one improvement suggestion with reasons. Rotate three times, then vote on best ideas. Groups revise original posters.
Critique what we would do differently if we ran this test again.
Facilitation TipIn Improvement Relay, time each group strictly to encourage concise feedback and prevent over-explaining during their turn.
What to look forPresent a scenario where a student's conclusion is not fully supported by their data. Ask: 'What evidence in the data does NOT support the conclusion? What could the student have done differently to get more reliable results?'

Activity 03
Whole Class: Data Debate
Display two class datasets on brightness vs. cells. Pupils vote on best conclusion, then debate reliability using evidence prompts. Tally changes in votes post-discussion.
Justify how we can prove that our conclusion is not just a lucky guess.
Facilitation TipFor Data Debate, assign roles like ‘Data Defender’ or ‘Improvement Advocate’ to ensure all voices contribute and debate stays focused on evidence.
What to look forObserve students as they record results from a hands-on circuit activity. Ask: 'What are you measuring here? How does this measurement help you answer your original question? What could you do to make sure this measurement is accurate?'

Individual: Reflection Ticket
Pupils complete exit tickets: one sentence conclusion, evidence bullet, one improvement. Collect and share anonymised examples next lesson for class patterns.

Generate Complete Lesson→A few notes on teaching this unit
Teachers should model how to phrase conclusions using the question stem, ‘Our data shows… because…’. Avoid accepting conclusions that merely restate results without analysis. Research in primary science shows that structured peer feedback helps students internalise the habit of linking claims to evidence. Use sentence starters on the board to scaffold precise language during whole-class discussions.
By the end of these activities, students will explain their conclusions using data patterns, justify reliability through multiple repeats, and suggest clear improvements to experiments. They will use precise language to link claims to evidence rather than vague summaries.
Watch Out for These Misconceptions
During Evidence Match-Up, watch for pupils who select a conclusion that simply restates the data without explaining the pattern.
Redirect them by asking, ‘Does this statement answer the original question? Use the word because to link the data to your claim.’ Provide a model statement on the board if needed.
During Improvement Relay, listen for groups that suggest improvements unrelated to reliability or control of variables.
Prompt them to focus on reliability by asking, ‘How would this change make your results more trustworthy? Use the word repeat or control in your suggestion.’
During Data Debate, watch for pupils who accept conclusions based on just one trial without questioning variability.
Ask the class, ‘What if the bulb had flickered in the second test? Would you still trust this conclusion?’ Guide them to demand multiple repeats to confirm patterns.
