Scientific Conclusions & Hypotheses

Science experiment illustration

🔬 Part 1: Reflecting on Your Previous Experiment

1. Briefly describe the experiment you conducted involving elements and chemical bonding. Include what materials you used and what you observed.
2. What was the main question your experiment was trying to answer?

❓ Part 2: Writing a Scientific Question

3. Based on your previous experiment, write a NEW scientific question that you would like to investigate. Your question should be about elements, chemical bonding, or reactions.

Helpful sentence starters:

• "What happens when..."

• "How does changing _______ affect _______?"

• "Does the amount of _______ influence _______?"

🧪 Part 3: Formulating Your Hypothesis

4. Write a hypothesis for your scientific question from Part 2. Remember: a hypothesis is a testable prediction based on what you already know.

Hypothesis Template:

"If _________________ (what you will change), then _________________ (what you predict will happen) because _________________ (your reasoning based on prior knowledge)."

5. Explain how you could test your hypothesis. What would you need to do?

📊 Part 4: Writing Scientific Conclusions

6. Using the data and observations from your previous experiment, write a scientific conclusion following the framework below:

Step 1: Restate the purpose/question of your experiment

Step 2: Summarise your key findings (what did your data show?)

Step 3: State your conclusion clearly (did your results support your original hypothesis?)

Step 4: Mention any unexpected results or errors you noticed

🤝 Part 5: Peer Feedback

7. Exchange your worksheet with a classmate. Read their scientific question, hypothesis, and conclusion, then provide feedback using the sentence starters below:

Feedback for my partner: _________________________

Your scientific question is clear because:

Your hypothesis could be tested by:

Your conclusion is strong because:

One suggestion for improvement:

Signed: _________________________ Date: _____________

🎯 Part 6: Self-Reflection

8. Why are hypotheses and conclusions important in science? Explain in your own words.
9. What is one thing you learned today about writing scientific conclusions or hypotheses?
10. Rate your confidence in writing scientific conclusions and hypotheses:

Very confident - I can do this independently

Somewhat confident - I need a little help

Not very confident - I need more practice

Not confident at all - I need lots of help
