How Do I Prepare a Science Project for an Egg Bounce?
Watching the reaction from classmates as you take a chicken egg and drop it to the ground, only to have it bounce instead of splatter is priceless. Preparing a science project for an egg bounce illustrates the power that an acid has in dissolving things. By placing an egg in vinegar, the shell dissolves and leaves the membrane behind. The result is an egg that bounces.

Put one raw egg in a cup and cover it with white vinegar. Put another two eggs in separate cups and cover each one with a different type of vinegar, like apple cider vinegar or rice vinegar. Using different types gives you variables to compare in your science project.

2
Let the eggs soak in the vinegar for three full days. Check on the eggs and write down your observations on any physical changes you notice. If you have a camera, consider taking digital photographs each day to give your science project presentation a visual component.

Remove the eggs after three days. Bring them outside and drop them from a height of about two feet. Any higher, and you risk breaking the egg. Observe the eggs bounce. Pay attention to the different vinegar types used and write down which ones bounce the highest.

Put your data and observations together in the form requested by your teacher. Include printed pictures, charts, graphs and write-ups that describe your science project.

5
Place two or three eggs in the vinegar again, three days before you bring the project to school. Remove the vinegar-soaked eggs when you present your science project, so you can have a live demonstration.
