Working on a science fair project can be both a fun and rewarding experience for students. The key to participating in the science fair is to find something that the student is interested in for the project. This way, the student already has an interest and is going to be willing to spend time and effort on his or her project. Make sure that your student, no matter how young, keeps an accurate notebook while working on the project. This notebook should contain information on all aspects of the projects and will aide your student in completing his or her display board. A fun thing to experiment with is eggs. The following is of experiments that can be done with chicken eggs. Try out some of these, even if you are not doing a science fair project. These are great projects to do with an entire class.

Is there any difference between white egg shells and brown egg shells?
Check out the strength of the eggs shells, by testing them as whole eggs.
Break the shells and try a variety of tests on the shells.
o How do they look inside?
o Can you draw with them?
o How much weight does it take to crumble them?
o Do the yolks look different?

Experiment with air pressure by having an egg sucked into a bottle.
Hard boil eggs.
Peel the shells from the eggs.
Sit an egg at the mouth of a glass jar that is slightly smaller than the circumference of the egg.
What happens?
Remove the egg and drop two lit matches into the jar.
Place the egg on top again and observe what happens.
What happens?

Will an egg float in salt water, fresh water, or both?
You will need two clear containers (they should be exactly the same).
Put fresh water in one of the containers and label it.
Heavily salt the same amount of water in the other container and label it.
Place one egg (approximately the same size) in each container.
What happens?
Which one floats?
Why?

Which end of an egg is stronger?
Use various weights and forces to answer this question.
You will want to use compression to test your eggs.

Can eggs bounce?
One dozen raw eggs, vinegar, and 12 plastic cups is all you will need.
Place the eggs in a container, completely covered in vinegar.
What role does the vinegar play in this experiment?
After about a week, the egg shells will be gone.
Try to bounce the eggs at different heights to see which one survives the drop.
This experiment can be messy, find a place to work that can easily be cleaned up.

Try to find a hard boiled egg, amongst a dozen raw eggs?
You will want to make various observations by weighing,
