Below is a fun egg science experiment called the cracked Egg Experiment. The Cracked Egg Science experiment is particularly useful in helping students understand the concept of plate tectonics.

What do I need for the cracked Egg Experiment? All you need to do the cracked egg science experiment is a medium cooked boiled egg. Below is an instruction to boil an egg to the right consistency. You don’t want an overcooked egg for this cracked egg science experiment.

How to boil an egg for this egg science experiment

1. Put water in a pot enough to cover an egg.
2. Bring the water to boil.
3. Lower an egg into the boiling water with a href=”http://www.science-experiments.info/Cracked-Egg-Experiment.html#”spoon.
4. Turn the heat down to low.
5. Boil the egg for about 7-9 minutes.
6. Take the egg out of the water to cool in under running water.

When you have a medium cooked egg, strike the boiled egg gently against a hard surface such as the kitchen countertop or a table. Break the eggshell into a number of pieces. Don’t worry about the size of the broken egg shell pieces. These shell pieces will be the tectonic plates of the earth, the boiled egg.

Now squeeze the boiled egg gently between two fingers. The plates will move and some will bimp against other plates. Other plates will slide or move away from each other.

The pieces of eggshell slide just like tectonic plates would. Some tectonic plates move towards each other, some move away, and so on. You can read more about plate tectonics here.

Question: Egg drop for my son..Science project?

My son has to do an experiment by dropping an egg from the top of the stadium without it breaking. He cannot use glass, metal, or fiberglass materials…Anyone have any ideas….Please.l…Thanks

Answer: I read about this in a scout magazine.

First build a safe box or something like that out of cardboard, bubble wrap, etc… for the egg to sit in. Fill the box so full of packing peanuts so that th egg can’t move around. Then, find the instructions to making a parachute. Make the parachute and hook it up to the top of the box. When dropping the box and parachute, hold the tip of the parachute, not the whole thing.

I think it’s against the rules to have it hardboiled.

Science Experiment

Below is a science experiment on the density of an egg. In this science experiment, we are going to explore the density of a raw egg in water and salt water. The video below illustrates this density of an Egg Experiment. This is a very simple density and eggs science experiment.

What you need for this density of an Egg Experiment

This density of an Egg Experiment is very simple and all you need is a cup of water, a cup of salt water and a raw egg.

The density of an Egg Experiment

Result of this density of a raw Egg Experiment

As you can see in this science experiment video, the raw egg floats in salt water but sinks in regular tap water. So, why did a raw egg float in salt water but sink in water?

By adding salt to water, you are increasing the density of water. Salt water is more dense than water and also more dense then the content of the egg, so the raw egg floats in salt water. But, the egg is more dense than water or water is less dense than egg, so the raw egg sinks to the bottom of the cup in water.
