Answer 1

This website can help you in what parts to include in a lab report: http://www.writing.engr.psu.edu/workbooks/laboratory.html
Your discussion should talk about the results of the experiment.
Was the hypothesis supported?
What conclusions can be made?
Was there any possible error in the experiment? (EVERY experiment has possible error)
Can another experiment be conducted to build on what has been learned from this experiment?
Things like that.
