I have a project in physics, in which the best works will get a high grade and will be put to the Science Exhibit. I have very low grades in Physics, and if I will not do well, I might fail. I need to do this very well...:

I need to find any topic in Physics and illustrate it in the most articstic way possible. It needs good content, impact, and I must do it within 1 hour (but the materials can be prepared at home). What should I do? What topic? How will I illustrate it?

THANKS FOR HELP!!!^_^

People,

I am curious to know the scientific reason as to why anyone should not eat during the eclipse, or why the cooked food & stored water should be thrown out after the eclipse.
Any answers ?

If you put a light bulb in a microwave and turn the microwave on, the lightbulb will glow then blow.

So why does the one fitted in the microwave by the manufactures not blow?

I really feel the answer is NOT the 'moon phase ' as we've always been told. I think the Asteroid that hit Earth millions of years ago caused it to continue rocking backwards and forwards, and this causes all the water on earth to shift one way or the other. Try it yourself, fill any objet with a bit of water and rock it constantly.. the water goes the way you rock it. Something just doesnt feel right about the moonphase issue..I feel the earths rocking is so slight, we cant detect it, or maybe geostationary satelittes can?

Is there simple equiptment that a child of 4-5 or at least under12 can use to make simple vidios. I know nothing...clean slate here..we do not even have a digital camera. THANK YOU

My Dad wouldn't take me to the zoo in case they wouldn't let me out again but now I've been with my mates. When we asked if there were any elephant rides, the lady was all snooty and said the zoo isn't an amusement park and their work was care and conservation. She talked as if we weren't welcome and we should just slide our entrance money under the door and bugger off.
