Science Fair Experiments Using Water Balloons

Science fair experiments using water balloons are the favorite projects for many science students. These can be physics science fair projects, they can be sports science fair projects or they can be chemistry science fair projects. If you are ready to have some fun with science then try all of these sample projects.

The force of gravity will cause water balloons to have the same arch angle when tossed. To test this hypothesis you will need to develop science fair experiments using water balloons. You will need three people for this experiment. Two people will toss the water balloon between them and one person will make the observations. You may also want to use a camera or video camera to record the arch created by the force of gravity when tossing the balloon. Is the angle always the same? Why or why not?

How far can you toss a water balloon without it breaking? This is an interesting topic for physics science fair projects. In these experiments you will want to see how far a water ballon can be tossed between two people without it breaking. There are a couple of variations of this experiment. The first option is to simply toss the balloon back and forth, the second option is to use padded gloves to catch the water balloon and the third option is to use a piece of stretchy spandex material to catch the water balloon. Your job now is to determine what can be done to stretch out the distance and to find the ultimate distance the water balloon can be thrown without it breaking.

Does the shape of the water balloon impact how resistant it is to breaking? To test this hypothesis you will need several balloons with different shapes. You will then fill each balloon with the same amount of water. The experiment will consist of tossing the balloons back and forth between two people. After each toss the people will separate another foot. Does the shape of the water balloon impact its ability to resist breakage?

Does the temperature of the water affect the water balloon's resistance to breaking? For these 1st place winning science fair projects your independent variable will be the temperature of the water you put in each balloon and the dependent variable will be how likely the balloon will be to break. Remember to use the same size and shaped balloons for each test.

Can a water balloon withstand more force than a regular balloon? To test this experiment you will want to stack books on top of a water balloon until it breaks. Count the number of books it takes to pop the balloon. Repeat this experiment with a regular balloon. Which one withstands more pressure and why?
