5. Reach a 5. Reach a ConclusionConclusion –– Discuss Discuss the resultsthe resultsthe resultsthe results

Discuss your results, whether you accept the hypothesis or not. What are the reasons for doing so.

What if your results do not support your hypothesis? That is perfectly fine. You're not out to "prove" your hypothesis but to test it. Think along the lines of "here's what Ibut to test it. Think along the lines of here s what I thought was going to happen, and here's what actually happened." Then go on to explain why you think things happened the way they did.happened the way they did.

Compare results with similar experiments carried out by others.
