Conclusions
👩 Teacher’s Guide
🎯 Objective
Students will be able to:
- Write a conclusion that answers the question using evidence
- State whether results support a hypothesis and why
- Identify anomalies and explain how they affect confidence in the conclusion
📝 Teaching Notes
- Key idea to emphasize: Main concept: conclusions must be supported by evidence and acknowledge uncertainty.
- Common misconception: Misconception: a conclusion is just restating the results table.
- Suggested teaching approach:
- Use claim-evidence-reasoning structure.
- Discuss whether evidence supports or refutes the hypothesis.
- Mention anomalies and how they affect confidence.
💬 Discussion Starter
Ask students:
- Why is evidence more important than opinion in science?
- What makes an experiment a “fair test”?
- How can scientists disagree and still make progress?

A scientific conclusion answers the question using evidence from the results. Strong conclusions explain the pattern, mention uncertainty, and avoid claiming more than the data shows.
Vocabulary and Definitions
- — The answer to the investigation question.
- — Data that supports the claim.
- — Explanation linking evidence to the claim.
- — A result that doesn’t fit the pattern.
- — A measure of how sure we are about a result.
Hands-On Experiment or Activities
Activity 1: Claim–Evidence–Reasoning
What You Need: CER template, sample results.
What You Do: Write a claim, select supporting evidence, and add reasoning linking the two.
Think and Talk: What changed? What stayed the same?
Activity 2: Support or Refute?
What You Need: hypothesis statements, results tables.
What You Do: Decide if evidence supports each hypothesis and write a short justification.
Think and Talk: What changed? What stayed the same?
Practice Questions (QA)
- What should a conclusion answer?
- What is 'evidence' in a conclusion?
- What is 'reasoning' in CER?
- If results are mixed, what should you do?
- Should you ignore anomalies?
- How can you show support for a hypothesis?
- Why avoid absolute language like 'proves'?
- What is one good way to increase confidence?
- What should you include about reliability?
- What should you suggest after a conclusion?
Reflection
- How could conclusions help you make a better decision in real life?
- What is one habit you can practice to improve your scientific thinking?
