Make Your Own Volcano!

volcanoBy Mandy Dillashaw, First Grade Teacher

Looking for something fun to do with your child over winter break? How about making a volcano! This exciting science experiment is easy to make and fun to do.

The volcano could be made out of clay (it will need to dry before you use it), a mound of dirt from outside, or any type of cup or container. If you use a cup or container, you could build up the clay around it to make it look more like a volcano! If you use a mound of dirt or clay for your volcano, place a plastic cup in the middle; old film containers also work great.

Here is a step-by-step guide to making an eruption!

  • Place about two spoonfuls of baking soda in the bottom of a cup
  • Add a spoonful of dish soap
  • Add about 5 drops each of red and yellow food coloring (optional)
  • Finally, add about an ounce of vinegar into the container and enjoy the eruption!

Here are two great websites that I like to reference for this project:

After your child completes the experiment, you could change some of the variables and explore different outcomes. What combination of baking soda and vinegar makes the biggest eruption? Does the temperature of the vinegar change the speed of the eruption? What could be added to slow down the “lava”?

Send us pictures of your volcano experiment and we will post them on our school Facebook page!

Have fun!
