Hey, welcome to AN

Normally the reason for your hypothesis would be in your introduction, but as your teacher has not told you to do an introduction, you do not need to provide a reason.
Your conclusion is just saying:
The results support/do not support the hypothesis that [repeat your hypothesis here] because [reason].
For example if your hypothesis were ‘more apples grow on each tree on average at farm A than at farm B’
Then your conclusion might be:
The results support the hypothesis that more apples grow on each tree on average at farm A than at farm B, as farm A had an average of 4.3 more apples per tree than farm B.
You should not try and describe all of your results, just one sentence that says why your hypothesis was supported or rejected.
Edit: Beaten to it, but I’ll leave this here anyway.
