Kids Science Project Idea – Green Eggs
This science project is unique in that it will turn an egg green, but the way it happens is very interesting and a great demonstration experiment.
Things you will need for the science project.
- egg
- red cabbage
- oblique
- Canned
- A bowl
- Oil
- A father to help
You are going to make a green egg and cook it, but you will not use any food coloring or anything green. Let’s go to the experiment and we can discuss the results and the hypothesis later.
Take the red cabbage and slice it as if you were making coleslaw. You won’t need a large amount of cabbage. A cup or two should do the trick. Place the cabbage pieces in the pot and pour in a cup of water. If you are using more cabbage, you may want a little more water. You don’t need much. Turn on the stove and leave it on high or fairly high heat. Let the cabbage cook a little. This could take ten to fifteen minutes. You want the water to get a nice purple-red color from the cooked cabbage. Then we will use the cabbage water. Once the cabbage has cooked and the water is a very dark purple color, it’s done.
Take your fresh egg and crack it. Separate the yolk into a small bowl and the white into a slightly larger bowl. Now take a tablespoon of the red cabbage water and put it in the bowl with the egg white and use the spoon or fork to stir.
Heat your frying pan or skillet and place a small amount of oil in the pan as it will cook the egg and you will need to prevent it from sticking. When the pan heats up for the colored egg white in the pan. You will notice that the egg white is green. You can also put the yolk on top of the egg white now to cook both together.
This will cook sunny side up because you don’t want to flip it as you want everyone to see the green color. When you’re done, you can obviously eat the egg. There is nothing wrong with it because the coloring was added by the cabbage.
Why did this happened? You took the purple food coloring from the cabbage and put it in the egg white and it turned green. You didn’t have the yolk involved in this. You only added the yolk after the white was cooked to finish the whole egg.
Why did this green coloring happen? What chemical process occurred? Was there any change in the egg shit itself?
This is a great science project for high school chemistry class.
