we have to have it protected in something, and my teacher has to be able to take it out and put it back in, and you have to be able to see the egg.

i was thinking of using bubble wrap.

if anyone has done this project before, what did you use and did it work?

If I have a list of presidents and when they were president, I can determine what years we had good presidents. If I have a list of presidents and where they were born, I can determine what locations produced good presidents. But if I combine that data, what good is it? So my question is how could data with both a time and spatial component be of any use?

i know that the reason diet coke and mentos go "BOOM" is that...

mentos act as a catalyst to the reaction and intensfy the release.

It's a process called nucleation, the carbon molecules get stuck in the bumps of the Mentos and that causes the oxygen to be left in a less dense state so it rises out of the bottle and takes liquid with it.

diffusion of two chemical substances namely carbon dioxide and oxygen.

and i know that...

its an exothermic reastion.

is all of that true? what else should i know for my project...please help me people...im in the 9th grade too.

Qoute"Symmetry surrounds us, both in the natural world and in the world of human artifact. As you walk around in the coming week or two, be aware of the patterns surrounding you-- the arrangement of needles on a pine tree, the sculpture in a hubcap, the vortices in the Mississipi River, the slats in a set of blinds."

The Problem: The TCO 99 standard from the FCC limits EMF (electromagnetic frequency) exposure to 2 mGauss, the term used to measure electromagnetic frequency, at a distance of 30 centimeters away from the front of a computer monitor. If I apply the regulation to 20 cell phones, how far do I have to be from a working cell phone to get an EMF reading of 2 mGauss, and will they comply with the TCO regulation?

It is hypothesized that a majority of the 20 cell phones that will be tested will conform to the regulation. To reiterate, at least 11 out of 20 of the cell phones will register 2 mGauss at a distance nearer than 30 centimeters.

So basically, I am using a guassmeter to measure and record if a cell phone's distance to 2mGauss is less or more than 30 centimeters. I just realized I don't have a control. :( :( :( :(

If you need more information, ask! I have it all on a word doc. Ready to copy and paste over.
