Why not build a model for “earth science” science fair projects?

Kids will be doing an “earth science” science fair project frequently throughout their school live. One early fun project for kids is to make a model of a metamorphic rock. People tend to forget that one of the five types of science fair projects includes making a model. Often when you are older the model will be included with the final presentation of an investigation project.
This project will show the effects of compression on metamorphic rocks. Heat and compression are what is needed over millions of years, to form these rocks, this earth science experiment shows the compression piece.
All you really need is modeling clay of different colors and and wax paper. And something really heavy. Five or six different colors of clay would make it easier to see when you are finished…
- It will be a simple process. Take the wax paper and spread out some clay on top of it, let them experiment with how thick it is Then layer the different colors of clay on top of each other, again they can make each layer a different thickness or make them all the same. You could make two sets of modes,l one with them all the same thickness and another with a mixture of thin and thick.
- Once you build you layers, put another layer of wax paper on top of the pile. Now you will be ready to make it metamorphic. Place a really heavy object on top of this pile. Three or four heavy dictionaries, or encyclopedias would work. Kids will have fun looking around the house for something really really heavy, to use.
- Let it sit awhile and when you pull it off you will see the effect of compression and how the different colors were pressed into each other, and one of your “earth science” science fair projects is complete.
This is just an example of an easy science fair project for kids to do, where visual “look” of the model becomes the best teacher. That is the whole point, isn’t it? You want the kids to learn something about science! This is just one of the many benefits of using simple, easy science fair projects for your kids next science fair.


Earth science projects are a cool way for kids to find out about the earth around them and learn more about science. There are a lot of “earth sciences” , so your kid has lots to choose from! Here are two of our favorites:
