Start on your experiment early. Don't wait later in the semester. Find something you are interested in and that would be fun. The plants I used for my experiment were really great because they were fast-growing. Make sure you only test one variable. Understand how to statistical analysis (t-tests or ANOVA). If you need help, seek out a math teacher. Also, ignore my chart for my strengths and weaknesses. Looking back, I should have written this in paragraph form. Also, it's usually not a good idea to include raw data in your report. Instead, put it in an appendix.
