So, after reading and talking about volcanoes, we decided to make our own personal ones. I learned that they had all seen the basic volcano eruption before in preschool, but they hadn't done the experiment themselves. Once I figured it out, it was an easy set-up and the excitement that was created was well worth it! (The picture below is how I set up the volcano making stations.)
1/3 of a can of playdough (I was making these with 60 kids, so they are small, but if you have less kids, you can use more playdough)
vinegar - tinted with red and yellow food coloring to make orange
1. Form your playdough into a volcano shape. Now, put a small indention on the top with your thumb. Not too big or deep!
2. Fill the indention with a small amount of baking soda.
3. Add a spoonful of vinegar to the top.
4. You have an eruption!
