Eat your science with a totally SWEET activity! Learn how to make edible geode crystals using simple ingredients I bet you already have! We love edible science because it’s a super fun way to get in the kitchen and experiment with all your senses! Connect with your kids and get started on AWESOME simple science activities.
HOW TO MAKE EDIBLE GEODE CRYSTALS SCIENCE ACTIVITY
Have you ever seen a geode or other precious stone and thought “I wish I could eat that!”
Now you can! Learn how to make edible geode crystals, and it’s is easier than you think. All you need are some hard candies and a few extra supplies from the kitchen to get started.

These edible geodes would be perfect to serve in class during a lesson on minerals and rocks, or you can have kids make them for a science-themed party! You can also add this to a summer science camp activities list.

Silicone muffin cups
Hard candies (like Jolly Ranchers)
EDIBLE CRYSTAL GEODES SCIENCE
Geodes are formed when a liquid mineral solution enters a hollow space inside a rock. Over many years the water evaporates, leaving a crystalized mineral inside the rock.
When the rock is cut open, you can see the crystals inside the rock shell.
These edible geodes are made by melting candy and forming them into a geode shape. But unlike real geodes, these geodes are formed by a liquid turning into a solid, rather than by mineral deposits collected over time.
LET’S MAKE EDIBLE CRYSTALS!
Here’s how to make your own edible geode crystals! Head to the kitchen, roll up your sleeves, and prepare for a super fun time with the kids. Kitchen science is the coolest!
Preheat oven to 300 degrees. Adult supervision is recommended with this activity!
Start by unwrapping your hard candies and place them inside a bag.
The kids will love using a rolling pin to crush the candies! It’s great heavy work for busy kids. Grab your muffin cups and play them on a baking tray.
Next you want to sprinkle a layer of candies on the bottom of your muffin cup. You can use two or three colors to make your candy look more like a real geode.
Have the kids do a little research on geodes and see what you can come up with for neat color combinations. Have you ever broken a real geode?
It’s time to heat the candies in the oven for about 5 minutes. You want the candy to be just melted when you take it out. Take the candies out of the oven and let them cool.
Once the candies are hard again, you can pop them out of the muffin cups and coat the edges with cocoa powder. This represents the rock coating surrounding real geodes.
REVERSIBLE CHANGE CANDY SCIENCE
More quick science: Applying heat to a substance will change it. Some changes are reversible and some changes are not. A reversible change is what you see here. The candy is not transformed into another substance when it’s heated. it just takes a different shape. What else can you think of that shows reversible change.
Grab your favorite rock hound book, arrange your geode slices on a plate, and enjoy!
You would be surprised by how much kids love science when they are given the opportunity to experience cool chemistry, physics, and earth science activities like learning how to make edible geode crystals!
If you have a rock collector in the family, this makes an AWESOME science activity to share together. Science is a neat way to turn off the electronics and connect with kids. Next time you are at the grocery store, toss a bag of hard candies in your cart!
