Mr. Russell’s Classroom: Making A Pumpkin Volcano With J-Stace

It’s time for today’s science lesson with J-Stace the Science Ace! You’re sure to have a BLAST with this experiment!  So, grab a pumpkin, carve it into a jack-o’lantern. You’ll need to leave out the light. J-Stace is showing us how to turn this crafty gourd into a volcano!

What You Need

  • One small pumpkin
  • baking soda
  • vinegar
  • food coloring
  • dish soap
  • water

Instructions

  1. First, get your pumpkin! Then you will need to hollow your pumpkin out.
  2. Find a container to put inside the pumpkin or use the pumpkin itself.
  3. Add the following to your pumpkin, bottle or container: Warm water mixed with food coloring filled to about 3/4 full; 4-5 drops of dish soap; a few tablespoons of baking soda.
  4. Then when you are ready for the eruption, add 1/4 cup of vinegar and watch with delight.

How Does the Experiment Work?

The baking soda is a base and the vinegar is an acid. When they combine a chemical reaction takes place and a gas is produced.  The gas is carbon dioxide which fizzes and bubbles.

Science Words of the Day

Neutralization is a chemical reaction, also called a water forming reaction, in which an acid and a base react and produce salt and water.
