These apple volcanoes combine the classic baking soda and vinegar reaction to create a fun and simple science activity for kids. We took this one step further and asked the kids to make predications. fall | science experiment | STEM

Our oldest starting doing volcano projects in preschool. With Daddy’s help, he built a paper mache volcano and used the reaction of baking soda and vinegar to create a volcanic eruption. For three years, they made one and did a demonstration for his classmates.


The Science


When you combine baking soda and vinegar a chemical reaction occurs that releases carbon dioxide. The baking soda (sodium bicarbonate) is a base while the vinegar (acetic acid) is an acid. When they react together they form carbonic acid, which breaks apart into water and carbon dioxide, and creates fizzing as it escapes.


Supplies


  • Baking soda
  • Vinegar
  • Dish or container to catch the fizz
  • Knife to cut center from apple
  • Apples

*We used Red Delicious and Granny Smith.


Testing


1. Prep your apples by cutting a hole in the top of each apple. (Dad completed this step.)

2. Put equal amount of baking soda in each apple.

3. Pour vinegar into each apple and watch it fizz.

4. Draw your conclusions. There was only a slight difference in the reaction between the two apples, but after a few test runs, we were able to draw our conclusions. The reaction of baking soda and vinegar produced more fizz with the granny smith apple. We believe it might be due to the higher acid content in this apple.


*We would love to see your apple volcano experiments and whether you have the same outcome. Tag us on Instagram or Facebook with your experiments.

I didn’t get a picture, but once they finished with their apple volcanoes, the kids had a fun sensory experience getting their hands in the fizz.
