Conclusion and Evaluation Guide

Conclusion
Paragraph 1: Purpose, procedure and hypothesis:
1st  sentence: Summarise what you found.     In this lab the researchers found that…

2nd sentence: Summarise the procedure (what you did)
The experiment was completed using … to see what happened when…
OR The experiment was performed by… in order to ….

3rd sentence: Summarise your hypothesis and say whether your hypothesis was proved correct. (NOT Yes my hypothesis was right but the hypothesis was proven correct or incorrect)
  The researchers predicted that… because….   OR The researchers predicted that if … then…
And if your hypothesis was correct:
This confirmed (or contradicted) our hypothesis

Paragraph 2: Background information - the science behind the experiment including vocabulary about the lab. (Think about the amount of light that is being blocked)

Paragraph 3: Summarize your results
1.       The experiment showed that....... DO NOT list EVERY bit of data just the main points or the overall patterns.
 Eg -What happens to the shadow as the light source gets closer to the block?
Explain the pattern (trend seen)– use examples from your results
Were  there any results that did not fit the trend/difference in the shadow? Suggest why this may have happened?
EVALUATION
What went well in your experiment
What went wrong, what happened  - how may it have affected your results?
