Volcano!!!

Last week as we finished up our study on volcanoes, we decided to make our own. First, Caleb made up a play dough recipe to form the volcano.

Then he and Josiah formed the mountain around a water bottle. They decided to add green food coloring to make it a volcano with a lot of vegetation growing on it.

Josiah adds baking soda and a few drops of dish detergent.

Then Caleb pours the vinegar mixture (colored red to simulate the lava). The eruption was all they had hoped for!! They were very excited (as you can see from Rachel's face).

  3. Okay, so how FUN does that look! Would you mind posting what you used to make the dough? Also how did you know how much baking soda to use and all that???

    I am picturing a fun science afternoon of volcano making in our future....Elizabeth if right BRAVE indeed!

  4. Here's the recipe for the eruption!!:

    In a 16 oz. plastic bottle (I used a water bottle) add 3 to 4 tablespoons baking soda. Add 3-4 drops dishwashing detergent. Then slowly add 1/2 cup of water.

    Mix 1/2 cup of vinegar with 3-4 drops red or orange food coloring.

    Slowly add the vinegar mixture to the bottle. The chemical reaction will then cause the eruption!

    As you can see from the pictures I used a cookie sheet with sides underneath it to contain the mess.

    Looking forward to seeing some pictures of your volcanoes!
