If you haven't done so already, be sure to check out Maxwell's equations. These are the four fundamental equations that define electricity, magnetism, and their relationship.

If your teacher wants your title to be a question then, in the interest of keeping your grade/self-preservation/etc, go ahead and use a question as your title. However, realistically speaking, titles do not have to be questions.

Hiramuzammal is correct: the title does not have to be a question, and generally speaking, titles are not questions. On the "project display boards" page, there is nothing that says the title has to be a question. Rather, the question is something else entirely which serves as the guiding ...

Is this being done with a camera, and if so, do these colored lenses actually refer to filters? Consider looking at how colors add and subtract from each other.

Something else you might want to consider is repetition of the experiment. Did you test more than once with water and more than once with gatorade? But you should consider about the order that you repeat the test and whether your muscles might be more tired from a previous test or your fitness migh...

Even if you're testing how colorblindness affects results of the Stroop test, I'd imagine that the main difference will only be that colorblind people will misname the colors they have trouble differentiating, which is obvious given their condition. Of course, if what's being tested is instead wheth...

Since the prices of different drinks are different depending on where you get them, you have an uncontrolled variable in your experiment (i.e., milk may cost $.50 at one store and $3.00 at another). To thwart this problem, you can stick to the manufacturers' suggested retail prices. By doing this, y...

As Ray said already, "American or foreign" will not suffice. Try to pick a few specific car models. It would be worthwhile to understand how car engines work and how hybrids work.

Unless the science project instructions ask specifically for why he wants to know how PSI of the air compressor affects depth and width of a hole, that information shouldn't be needed. Stick to being objective unless otherwise instructed.

Raw data refers to unprocessed data. The easiest way to show this would be to include a table with all the numbers you recorded. Ideally this table would precede your graphs. As Terik said, graphing each trial separately would probably be best.

In addition to the mean, you may want to give a measure of spread. If for each color the distribution is relatively symmetrical, consider using standard deviations. If not, consider using IQR.

For the graph, one possibility would be to do a curve: # of crickets vs. color wavelength.

Hope that helps.

You could also set the variable as the strength of the UV light (e.g. 0 W, 150 W, 300 W, etc).

As already stated, E.coli can be used. I believe yeast works also.
