Scientific Conclusion Writing

Science experiment illustration

🔬 Part 1: Cut-Up Sentence Ordering Activity

1. Work with your group to cut out the sentences below and arrange them in the correct order to make a good scientific conclusion. Write the numbers 1-8 in the boxes to show the correct order.

Our hypothesis was that the ball would roll faster on the smooth surface than on the rough surface.

This happened because there was less friction on the smooth surface, allowing more energy to transfer to movement.

The aim of our investigation was to find out which surface would make a ball roll faster.

Therefore, our hypothesis was correct.

The ball rolled 2.5 metres on the smooth surface but only 1.2 metres on the rough surface.

In conclusion, smooth surfaces allow objects to move faster than rough surfaces.

Our results showed that the ball travelled much further on the smooth surface.

Rough surfaces create more friction, which slows down moving objects by converting kinetic energy into heat energy.

📝 Part 2: Conclusion Writing Organiser

2. Use this graphic organiser to plan your own scientific conclusion. Fill in each section using your recent experiment.

A. Restate the Question/Aim

What was your investigation trying to find out?

B. State Your Findings

What did you observe? What were your results?

C. Compare with Your Hypothesis

Was your hypothesis correct? How do your results compare?

D. Scientific Explanation

WHY did these results happen? Use scientific reasoning to explain.

💡 Part 3: Sentence Starters - Choose Your Level

Support Level - Use These Sentence Starters:

3a. Copy and complete these sentences for your conclusion:

Restate the Question: The aim of our investigation was to find out ________________

State Findings: Our results showed that ________________

Compare with Hypothesis: Our hypothesis was ________________ because ________________

Scientific Explanation: This happened because ________________

Challenge Level - Advanced Sentence Starters:

3b. Use these more complex sentence starters to write a detailed conclusion:

• Although we predicted that...

• The data clearly demonstrates that...

• This can be explained by the scientific principle that...

• Furthermore, the relationship between... and... shows that...

• Therefore, we can conclude that...

✍️ Part 4: Write Your Complete Conclusion

4. Now write your complete conclusion paragraph using the organiser and sentence starters above. Remember to include all four parts!

🎯 Part 5: Self-Assessment Checklist

5. Check off each part you included in your conclusion:

I restated the aim/question of my investigation

I clearly stated my main findings/results

I compared my results with my hypothesis

I included a scientific explanation of WHY the results happened

I used scientific vocabulary correctly

I used linking words (because, therefore, as a result)

6. One thing I could improve in my conclusion writing:
