Fun Science Projects

We have a number of short Examples Of Science Fair Projects. In this short easy elementary science projects we are going to see some of the interesting things that happen because of the density of liquids. The density of and object has to do with how tightly packed the object is. Two objects can weigh the same but one is smaller than the other, the smaller one is packed more tightly and is therefore denser than the other object. These experiments are meant to make learning fun and are also very suitable for homeschoolers.

The floating egg experiment

What you will need for this easy elementary science project:

A container

Water

An egg

Salt

A spoon

This is what you have to do for this easy experiment:

Fill the container with enough water to cover the egg completely.

Carefully place the egg in the water.

What happens to the egg?

Make a note of what happens.

Start adding salt to the water and stirring it very carefully so as not to break the egg.

Keep on adding salt until your egg starts to float.

You will need quite a lot of salt, about 4 tablespoons full of salt per 1 ½ cup water to make the egg float.

Now you add water to your solution again until the egg start sinking again.

Keeping density in mind, try and explain what just happened.

If you worked carefully and did the experiment the right way your egg started rising because it became less dense than the water when you added the salt. When you added extra water, the water once again became less dense than the egg and the egg started sinking again.

This is one example of our easy elementary science projects, one of many examples we have of science fair projects.

Check out fun science projects. Thanks!
