ok, i need some help to find a great science fair experiments. I am too a science geek, lol but i just need some more ideas. Ideas for like 8th grade through high school would be great.
Like what i am looking for is like what i can prove to the judges with my experiment. Maybe in binders or something that i can prove my Hypothesis and that make sense.
Thanks for the help
P.S. Plz no tornadoes in bottles or stuff that easy.
Easy but not that easy. Stuff that would be okay in a school building. So nothing dangerous.

Thanks again

I read an article a while ago about how scientists want to send a submarine to jupiters moon Europa to search for underwater life;
The article told of how it would melt its way through the thick ice but I could not locate that same story again and I just thought I would ask, What is your opinion on this, Possible? Or not possible?
Science shows it can be done, They will be testing in an antartic lake in 2008 and 2009 to see if its possible,,;
Whats your thoughts?

Here is a short description of the program testing, and the concept,

And another that tells about the concept on Europa;

Ughhh, I absolutely hate bugs. They're always where I happen to be. Like the other day I was just sitting there watching TV, when this HEEUUGEE (and I mean huge) centipede crawled up my leg. I screamed and jumped all over the place. Then the next day, in the shower, there was this big black/red spider just sitting there right in front of my face. I screamed and ran out of the bathroom. Later that day, I was walking home from school and this fat bee stung me on my forehead! And once I was in the pool and there was this scorpion floating there. I ran away and tripped over a sun lounger.

Uggghhhh, bugs why are we so afraid of them?

I don't know if this is a natural occurence, but I saw it, and it was stunning. On the day of December 29, 2007, at around 3:30 AM (GMT+8, Manila), me and my cousins were just finishing up our game of poker at my rest house in the suburbs, when I decided to walk around our yard while smoking. Anyway, I looked up in the night sky, and there was this big, cleared-out, perfect circular "hole", and the moon was right smack dab in the middle! It's like, imagine a bowl, turn it upside down so that the concave faces you, and the moon is right in the middle. It was relatively hazy that night (but there were no rain clouds). The most puzzling thing is that, if it was just a blanket of cloud that was seemingly cleared out by the moon rays, then why, when a high-flying aircraft crossed this "hole" with its tail emitting a smoke trail, the perfect circle hole was not ruined at all? Is there an explanation for this "phenomenon" if I can call it one? Thanks. :)- reypasco818, Manila, Philippines

Momentum is the product of mass & velocity; therefore, photons must have mass, however minute. If there is mass to light waves, why not mass to the whole range of the electromagnetic spectrum? Could that mass result in measurements of "dark matter" which is not visible and is unknown in its nature?

I'm trying to differentiate arcsin3x (with respect to x)
The answer is -24/sqrt(1-(3x)^2) but I can't get it right.

I tried the product rule and got 3x.1/sqrt(1+x^2)+3arcsin

Any chance of showing my the correct steps?

A pebble is dropped into a cal pond, causing ripples in the form of concentric circles. The radius (in feet) of the outer ripple is r(t)=0.6t,where t is the time in seconds after the pebble strikes the water. The area of the circle is given by the function A(r) = pi r squared. Find and interpret (Aor)(t).
