Hey does anyone have any good science fair ideas?!?!?

I got a first place years ago for one of my projects. "Which Battery actually lasts the longest?" I set up a board, made connectors to put the batteries in, connected them to small lights, turned it on and kept a record as to when the lights would go out. The last light left on wins! Good Luck!

maybe u should do an original by making a volcanoe or if u're really smart maybe u can make a robot.u can demonstrate how fashion is important to our society and how it defines someone by how they are. maybe demonstrate ur fave hobby in a scientific way, like how gravity pulls u back down when u're jump roping and how the force from ur legs pushes u back up.

Well, Here's what I did. I had 4 sodas: Pepsi, Diet Pepsi, Coke, and Diet Coke. I dropped 6 mentos into each one. The reaction of all sodas is that after you drop 6 mentos in then a whole bunch of the soda bursts out of the top. I recorded the amount of time it took until the soda stopped bursting out of the bottle for each soda, I measured each soda after I attempted to do this and then I found out what kind of soda burst highest(Regular or Diet), Which one burst the highest(Pepsi, Diet Pepsi, Coke, Or Diet Coke), and which one bursted the highest in the shortest amount of time. Then I wrote all of it down onto a piece of paper. It's an extremely fun and easy project! It took me less then an hour to do, and about 2 days to complete. E-Mail me at the following e-mail address: [email protected] if you want to see pictures of the project and the sodas. Good Luck, Phil P.S I got in 2nd place on this project!

how about bottled water.. what brand is actually more health for you. (ie bacteria wise or chemical wise) you can always have that compared to distilled water.. and tap water.. and water from a well.. you can always take the samples down to an environemental lab.. they can tell you about the techniques and all the science that goes behind it :)

i grew tomato's in different types of soil different types of light different types of fertilizers to see what combination produced the best tomato.

Put Pepper in water then when the top is filled put a drop of dishwasher soap in the middle and the peeper will scatter away from the soap

You could do Rube Goldberg. Or also do a specific problem-resolution, such as what does acid rain do. You could compare cell-phone frequencies out in the middle of nowhere. Lastly, you could prove that their are aliens living in outer space. That would blow them away.

Hmm... Volcano... no... To predictable... How about the effect of music on animals... Just study and show people how like a dog reacts to different kinds of music...
