MFA Kids | Learn About Geology

What is Geology?

Geology is the science of the earth’s physical history, its rocks, and the physical, chemical, and biological changes that happen to it. We put together this book that helps tell the story of our planet and shows geology in action.

1. Watch the Video

Watch this video to learn about the shapes we find on Earth, such as mountains, which are called landforms.

2. Complete the Activity

You can try creating your own landform by growing salt crystals! This simple project from Science Kids will teach you to create crystals that are beautiful to look at, much like the rocks that we find all around our planet.

What you’ll need:

  • 8 oz. jar
  • Water
  • ½ cup salt
  • Spoon
  • String
  • Scissors
  • 1 pencil


  1. Fill the jar with water
  2. Add ½ cup of salt to the water
  3. Mix the solution with a spoon
  4. Cut a piece of string that is about half as long as your jar
  5. Tie the string to the middle of the pencil
  6. Place the pencil over the top of the jar so that the string dangles into the middle of the solution and the pencil hangs over the edge of the jar

What next?

Leave the experiment in a safe place for a few days and wait for salt crystals to form along the string. Crystals can be found grouped together as lots of small crystals or as huge individual crystals. Try collecting a range of crystals for your project, name and label the different types, and make a rock collection box to keep them in.

Bonus Activity

Now that you’ve made salt crystals, ask your parent for help boiling water to make your own rock candy! All you will need is water, sugar, wooden sticks, and food coloring.

3. Complete the Coloring Page
