Hi Pink Bear,
Welcome back! Congratulations on your second place in last year’s science project. It sounds like you’ve put a lot of work and effort into choosing a project so far.
Here are just a couple of comments that might be helpful. You should definitely pick a project that you are interested in. To have the winning project, you will probably have to do something a little more than what is outlined in the project guide, but once you decide which project you are going to do, perhaps we can help you think of something to make the project idea more challenging and creative:
1. Forensic science. It doesn’t sound like you’re really interested in this project, which involves building an electrophoresis unit. However, this is a great project, and if your only concern is that you don’t understand the variables, don’t worry. We can explain this to you. However, if this is not intrinsically interesting to you, I would recommend doing one of the other projects/.
2. Botany project. You’re experienced in botany, so you could build on your success by doing this project. However, is it going to be warm enough for you to grow morning glories for this project? If not, then you won’t be able to get results. You absolutely need results for a winning science fair project. Since this is a kit, you would need to do more background reading and do something to make the project more creative. But if you like botany, go ahead and pick this project.
2. Fear project. I agree with you. This is an incredibly interesting project. However, in my experience, science projects that involve measuring blood pressure generally do not give good data, and since you will be entering a category with lots of competition, you need to have really good data. Blood pressure is notoriously variable, so I would recommend finding another dependent variable to measure in addition to blood pressure, or instead of blood pressure.
Also, since you will be working with humans, you will need to check with your local scientific review committee and plan to get informed consent from all of your subjects.http://www.sciencebuddies.org/science-f ... _src.shtmlhttp://www.sciencebuddies.org/science-f ... ects.shtml
It’s your project and your decision and I think you could be successful with any of these projects. Once you decide, reply to the post, and we’ll try to give you specific suggestions that will help make your project a winner.
