STEAM Team Experiments

Volcanoes!

This past week young scientists joined the STEAM Team to conduct science experiments about volcanoes. We talked about how volcanoes form and what causes eruptions. Then we made our own model volcanoes, and of course, made them erupt!

In case you missed it or want to re-create your volcano at home, here's what we did:

First we learned about volcanoes using these two books:
Inside VolcanoesInside Volcanoes by Melissa Stewart
Examines the nature of volcanoes, how they are formed, what they look like, and how they are measured, in a text with ten fold-out pages.
An Island Grows by Lola M. Shaefer

Volcano ExperimentThen it was time to start experimenting! 

Supplies:
  • Salt dough
  • Paper Plate
  • Small plastic cup 
  • Water
  • Liquid dish soap
  • Baking soda
  • White vinegar
  • Measuring spoons and cups
Process:
  1. Put your plastic up in the middle of your paper plate with the opening on the top. The plate represents the Earth's surface, and the cup the volcano's magma chamber.
  2. Use your salt dough to form the volcano around the cup.
  3. Once your volcano is ready fill the cup about 2/3 full of water.
  4. Add about a teaspoon of liquid dish soap (this will add bubbles to your "lava").
  5. Add 2 tablespoons of baking soda.
  6. Slowing add vinegar until the volcano erupts.
 
VolcanoMore Fun:
  • Try testing our different ratios of baking soda and vinegar, what changes?
  • Try reforming your dough into different shapes, how does this affect the flow of your "lava"?
  • Can you build a larger magma chamber and volcano?
