Day One: Math & Home Economics--mixing the dough and forming the volcano.
They love to measure and stir.
We used a glass juice bottle from Trader Joe's for the center of our volcano (you have to have a container in the center to pour the baking soda and vinegar into).
We added some trees to the landscape while the dough was soft. Plan on a week or more for drying time--unless you spread the dough quite thin.
Day 2: Art!
Paint the volcano.
I love those pudgy little hands with the paint brush.
I left the kids for five minutes while they were painting and they started tearing the volcano apart. The dough had gotten soft from soaking up the paint and they were able to peel chunks off and throw them at each other. What a mess. I got frustrated and this is probably the reason I let the project sit for so long before finishing it.
Day 3: Science
Day 3: Science
All the necessary materials--this is not an expensive project--perfect for a recession : ) You could add red food coloring if you want, but remember the stain-potential.
I didn't have a funnel, so that is baking soda all over the rim of the volcano. Then I carefully added the vinegar--we had to use a lot of both since our volcano was so tall. The kids can create the reaction in small dixie cups using a lot less baking soda and vinegar. I forgot to let them try that today, but when Ezra took a science class, that is how they did it. They can cause reactions to their heart's content.
And the eruption flows down the volcano--make sure you do this outside, or have a big huge old sheet on the table to catch the flow. The kids want to make it re-erupt as many times as I let them, and we used up about 20 ounces of vinegar--it all has to go somewhere!
