Answer 1

Whose mouth is cleaner, a dog's mouth or a human's mouth?"

Start off with 4 petri dishes filled with gelatin. Then take a swab of your mouth, a friend's mouth, your dog's mouth and your friend's dog's mouth. Put these all in separate petri dishes. Then observe the growth of different molds and fungus on the swabs.

The idea is to see which soda contained the most fizz out of Cherry Pepsi, regular Pepsi, Mountain Dew, and Coca Cola. To make your hypothesis, just know that carbonated water is what fizz is and the soda with the most sugar in it will have less room for carbonated water. The one with the most sugar will have the least amount of fizz.

Take at least 5 different types of balls...(relatively the same size)-tennis ball, baseball, raquetball, golf ball, ping pong ball, etc...and see how high they bounce on a variety of surfaces...(wood, tiling, ceramic, brick, concrete, etc..) Then make a conclusion on why they act the way they do!

Answer 2

Yes there is. Try this one:

"Which manufactured disposable paper towel is the strongest when wet."

In your discussion tell how you set up the experiment, and label each brand... Write your discussion on the boards that are the background for your project.... the size of the boards are usually part of the rules determined by the project outlines....

The go out and buy some paper towels made by 6 different manufacturers. Put the same amount of sand in each, and tie with rubberbands. Lower each into a cup of water, and suspend. The one that lasts the longest is the strongest. Take photos and use them in your demo. You for sure will have to try to make the sand pretty heavy -- so that all will break before the water can evaporate.... (hint -- usually Bounty will win, but you don't need to speculate that in your hypothesis... Discuss how much sand you used, how much water each soaked up, and time each took to break....good luck
