What is a good topic/subject for a science fair project?

Question

I am now in the 8th grade and just started school. The science fair is coming and I need some good topics to turn in. So far some of my topics are global warming and forces. If you could give me some links that would be great too!

Answer 1

I LOVED science fair. In 7th grade, my project was about crystals. In 8th, my project was "Can dog saliva kill bacteria?" It made it all the way to regionals!!!

"Global Warming and forces" are MUCH to HARD to do. ONE there is no QUESTION what-so-ever. A good science fair project ANSWERS a question, Such as, "Do magnets effect compasses and by how much?" OR "How clean are fast-food restaurants?" OR "What is TRUELY good for you to eat?" <<(where you could test amounts of chemicals and pestisides on veggies and fruits.) OR, another one is "How much pH is in facial cleaners and lotions?" OR "How does soda effect teeth compared to _________?" <<((Where you could take baby teeth and soak them in coffee and soda and other drinks and measure how long (in years) that approximately would be and show the long term effects pop has on teeth.))

All these projects seem REALLY fun. What you have to find is 1.) Something your intrested in (science fair takes like 2 to 3 months); 2.) Do your project on something that will hold your intrest for that long of a time; 3.) Answer a question. (Make sure your project asks a question so while your experimenting, you work to answering that question in your results); and 4.) Pick your project and HAVE FUN while experimenting. Don't just procratinate, once you pick your project, focus on it, perfect it, and ENJOY it!!!!. ((Make sure you make a hypothesis and follow the scientific method.!!!))

Those topics are much to broad.  Maybe you could do something like, "How much will carbon dioxide heat a simulated atmosphere?"

You could set up a few simulated atmospheres in small aquaria.  Cover them so the "atmosphere" doesn't float away, and put thermometers in each so you can read the temperatures.

Make CO2 by mixing baking soda and vinegar.  CO2 is heavier than air, so you can pour the invisible gas.  Use measuring cups to add 1 cup to one "atmosphere," two to the second, three to the third, etc.

Then put them in the sun, and measure the change in temperatures over the course of an hour or two.
