Setting up an apple volcano science experiment for preschoolers is a great way to engage them in an awesome STEM activity this fall!
As you begin planning your preschool apple theme, you won’t want to miss this awesome hands-on activity for little ones. They’ll love watching the bubbles pour out of their “volcano”!

If you’ve been teaching preschool for any length of time, you’ve probably got a good collection of back-to-school activities. I bet you teach apples during August or September.
Apple Volcano Science Experiment
This preschool science experiment is a great way to explore color mixing and chemical reactions with your preschoolers.
What You’ll Need
- 1 apple
- 1-2 tbsp. Baking soda
- 1-2 cups of Vinegar (in a squeeze bottle works best)
- Spoon
- Tray
- (Optional: food coloring)

Preparing the Experiment
Adults will need to cut a hole in the top of the apple. Be careful with this step!
Then, place the apple in a tray to catch the spills.
What You’ll Do
Have your child fill the hole in the apple with baking soda.
Using the squeeze bottle, squeeze the vinegar onto the baking soda and watch the eruption!
When the fizzing slows down, add more baking soda and repeat the steps as many times as you wish.

Add fun food coloring if desired for more fun! For this experiment, we used the colors of the rainbow.
Refill the apple with more baking soda.
Add 1-3 drops of each color of food coloring around the baking soda.
Pour the vinegar in the center of the apple and watch the different colors start to flow from the apple!
Skills Taught
Hand-Eye Coordination – It takes a little practice to scoop the baking soda into the hole in the apple. At first, kids might make a bit of a mess as they get the soda close to the hole but not in it. With practice, they’ll get more and more accurate.
Fine Motor Skills – Squeezing the bottle of vinegar is a great way to strengthen fine motor muscles in your child’s hands and fingers.
Chemical Reactions – Kids will love watching the way baking soda and vinegar react. They’ll beg to do this activity over and over again.
Color Mixing – If you choose to add food coloring, you can introduce color mixing to your preschoolers. You can use all the colors of the rainbow. Or, you can explore mixing blue and red to make purple, yellow and blue to make green, and red and yellow to make orange.
