Drawing Conclusions and EvaluatingActivities & Teaching Strategies
Active learning helps Year 3 students internalize the link between evidence and reasoning in science. When pupils analyze real data in small groups or pairs, they practice drawing conclusions in a supportive setting that mirrors how scientists work.
Learning Objectives
- 1Evaluate whether experimental results support or refute an initial prediction.
- 2Justify conclusions drawn from collected data using specific evidence.
- 3Suggest at least two practical improvements for a future investigation based on observed limitations or findings.
- 4Compare the outcome of an investigation with the initial hypothesis, identifying similarities and differences.

Small Groups: Results Review Relay
Provide groups with a recent experiment's data table and prediction cards. First, pupils match data to predictions and write one conclusion sentence. Then, pass to next group member to add an improvement idea. Groups present their chain to the class.
Prepare & details
Evaluate whether the results support the initial prediction.
Facilitation Tip: During the Results Review Relay, circulate and ask each group, 'Which piece of data makes you most confident in your conclusion?' to keep the focus on evidence.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Pairs: Conclusion Match Game
Prepare cards with predictions, results, and conclusions from past investigations. Pairs sort and match them, justifying choices with evidence. Discuss mismatches as a class to refine understandings.
Prepare & details
Justify the conclusions drawn from the experimental data.
Facilitation Tip: For the Conclusion Match Game, provide sentence starters like 'The data shows that _____ because _____' to guide pairs toward evidence-based conclusions.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Whole Class: Improvement Idea Wall
Display experiment photos and results on a wall. Students add sticky notes with improvements, such as better measurements or fair tests. Conduct a gallery walk where pupils vote and explain top ideas.
Prepare & details
Suggest improvements for a future investigation based on current findings.
Facilitation Tip: On the Improvement Idea Wall, invite students to write their suggestions on sticky notes using the sentence frame 'We could improve _____ by _____' to make proposals concrete.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Individual: Reflection Journal Entry
Pupils review personal experiment logs. They write: Does data support prediction? Why? One improvement for next time. Share select entries in a volunteer circle.
Prepare & details
Evaluate whether the results support the initial prediction.
Facilitation Tip: In the Reflection Journal Entry, give a specific prompt such as 'What pattern did you see in the results? How does it connect to your prediction?' to scaffold metacognition.

Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Teaching This Topic
Teachers should model how to talk about uncertainty when results do not match predictions, normalizing the idea that investigations often lead to new questions. Emphasize oral rehearsal before written tasks so students practice explaining their conclusions aloud. Avoid rushing to 'correct' mismatches; instead, guide students to examine variables and adjust their claims.
What to Expect
By the end of these activities, students will state conclusions that directly reference their data and suggest at least one improvement. They will use terms like 'evidence,' 'pattern,' and 'fair test' naturally during discussions and writing.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring the Results Review Relay, watch for students saying the experiment 'failed' when predictions are not met.
What to Teach Instead
Pause the relay and ask each group to share one piece of data that surprised them, framing surprises as new evidence rather than outcomes to avoid.
Common MisconceptionDuring the Conclusion Match Game, watch for conclusions that restate results without linking to predictions.
What to Teach Instead
Have pairs exchange conclusion cards and highlight the prediction sentence in one color and the evidence sentence in another, then revise together to show the connection.
Common MisconceptionDuring the Improvement Idea Wall, watch for students who only suggest improvements when something breaks visibly.
What to Teach Instead
Prompt groups to review their data sheets for uncontrolled variables and ask, 'How could we make this test fairer?' to uncover overlooked opportunities for improvement.
Assessment Ideas
After the Reflection Journal Entry, collect journals and note if each student’s conclusion ties to data and if the improvement is specific and testable.
After the Conclusion Match Game, ask pairs to share one conclusion that used strong evidence and one improvement idea, listening for use of the terms 'pattern,' 'evidence,' or 'fair test'.
During the Results Review Relay, listen for students to point to specific data points as they explain their conclusion to you, indicating they can articulate evidence-backed reasoning.
Extensions & Scaffolding
- Challenge early finishers to design a follow-up experiment that tests a new variable suggested by the class's improvement ideas.
- Scaffolding: Provide a partially completed table with missing evidence cells for students to fill in before writing their conclusion.
- Deeper exploration: Ask students to predict how their improvement idea will change the results, then test the prediction in a mini-experiment the next day.
Key Vocabulary
| Conclusion | A summary of what was learned from an investigation, based on the results and evidence collected. |
| Prediction | An educated guess or statement about what will happen in an investigation before it begins, often based on prior knowledge. |
| Evidence | Information or facts gathered during an investigation that support or refute a conclusion or prediction. |
| Improvement | A change or suggestion made to make a future investigation more accurate, fair, or reliable. |
Suggested Methodologies
Planning templates for Science
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
RubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
