How on earth does a mother bird sit on her eggs without crushing them? Surprisingly, the shape of the eggs protects them from being crushed when even pressure is applied to them. You can use this fact as a basis for some interesting egg science fair projects. For example, see how much weight it takes to crush a group of upright eggs, and then compare that with the amount of weight it takes to crush a group of eggs that are lying down. (Make sure that the eggs are secured before trying this experiment.) Alternatively, you can use different types or sizes of eggs, or eggs from different animals if you can obtain them, to see which ones can withstand the most pressure.
A typical egg demonstration used in science classes shows how an object that is less dense than water will float, whereas an object that is denser than water will sink. This demonstration involves placing a raw egg in water and explaining that it sinks because it is more dense than the water around it, and then adding salt to the water and explaining that the egg floats because now it is not as dense as the salt water around it.
You can use this basic demonstration to generate your own egg science fair projects. First, find out exactly how much salt needs to be added to make the egg just sink beneath the surface. Then use this information to see whether the density of the water is affected by factors such as the depth of the container, the amount of water in the container, or the temperature of the water. Remember to create a strong hypothesis before testing it!
Eggs vs. Egg Substitutes
Looking for different types of egg science fair projects? What about looking at the differences between real eggs and egg substitutes? After all, companies that make egg substitutes advertise that they are “just as good as real eggs," right? You can put together a stellar science fair project exploring whether their claims are correct.
To do this, you’ll need to bake several recipes in which the eggs help the product to rise. For example, you might make brownies, bread, and cake. For each recipe, make several versions of the recipe – one using real eggs, and the others using different types of egg substitutes. Then measure the height of the baked products and insert your results into a table. You can then use your results to come to a conclusion about whether egg substitutes truly do work as well as authentic eggs.
