9th grade science projects are more involved than elementary school projects, but still involve the same basic requirements, a question, a hypothesis and a conclusion. However in high school you need to focus more on the presentation of your project, as high school students are expected to be familiar with word processing programs and printers.
You will also need to reference any place you obtained information from during your research. Other interesting 9th grade science fair projects might be seed germination; can you improve the germination rate of seeds by soaking them in a chemical before planting them?
Some chemicals you can try are fruit juice, hydrogen peroxide, diluted isopropyl alcohol, etc. It is thought that some of these chemicals can loosen the seed coating around the plant embryo. Another science project could be researching whether or not listening to music while studying can affect your ability to retain information.
You could find out whether the presence of smoke in the air affects plant transpiration. Perhaps you could look into whether or not there is ever acid snow, we all know there is acid rain, but what about snow? You can find this out by testing the PH level of the snow and comparing it to the PH level of acid rain. Obviously this particular project only works in the winter months. There are many great topics out there for your 9th grade science project, it's just a matter of finding one that interests you, researching and testing it out and presenting it in a professional manner.
