Make sure you describe the scientific principles used in the experiment. This is very important so that your reader is able to repeat your experiment and get similar results. Remember that as you write, it is your job to show the reader why your thesis is true! To do this, you will have to make sure to include an explanation of how and why the evidence supports your thesis. Write in full sentences and avoid contractions. It’s a good idea to use transitional words (e.g., “next,” “in addition,” “first,” etc.) in order to help the reader follow along. Do not forget that your main goal is to convince the reader of your viewpoint, so you have to be persuasive enough. By sitting down and organizing all the information that needs inclusion in an outline first, this can help you decide on which facts and figures are worth mentioning and which ones should be ignored or omitted altogether.
