From raising chicks to cooking breakfast to decorating for fun, eggs have a wide variety of uses. You can even use eggs to conduct educational science experiments with your virtual school students!
It’s time to crack open some eggs and make your own geodes. The Egg Geode Experiment is designed to help students in grades K–5 discover how crystals grow. Just a few of the concepts you can cover with your child during this experiment include solvents and solutes, chemical reactions, and geology.
Take a look at the Egg Geodes instructographic below to see the directions for this experiment.
How Much Do You Know about Geodes?
What are geodes?
Geodes are hollow rocks that have a mineral formation inside.
Did you know…
Not all geodes have crystals inside. Some have more colorful formations of minerals such as agate and jasper, and sometimes the insides are solid.
Where do they come from?
Geodes come from sedimentary and igneous rock. They are created when rock forms around a pocket of gas or an empty space in the earth. You can find a lot of geodes in the Midwest, particularly where Illinois, Iowa, and Missouri meet.
How do you identify a geode?
Geodes are typically round or oval with a somewhat lumpy surface, but you can’t determine exactly what’s inside it until you break one open.
Although the eggs are already broken in this experiment, their shells give the homemade minerals a place to form. Let ...
