Yesterday afternoon was volcanic. We watched videos, read books, colored pictures, investigated pumice, made a Sculpey lava flow, and created an erupting volcano. Even with all that, I think the boys could have kept going the rest of the afternoon.
We're on Unit 2, Lesson 5: Volcanoes of the Christian Kids Explore Earth & Space and there are perfectly good instructions for simulating your own volcanic eruptions in the lesson, but I already had this kit stashed so I brought it out:
Never mind that I neglected to read all the instructions and gather necessary household items beforehand, and didn't have club soda, and didn't want to make a plaster and sand volcano that would have to dry 24 hours before creating the eruptions--we were erupting a volcano that afternoon!
Good thing I know how to make a giant glob of salt dough, and had a few liters of Coke sitting in the basement (for the Steve Spangler Mentos-Coke geyser).
The children globbed the salt dough onto the kit's plastic volcano form:
We prepared the eruption ingredients:
Filled the volcano's crater with Coke:
Threw in the kit's tablets (which are mostly baking soda and red food coloring), and watched the eruptions:
Of course, you don't need a kit (or even salt dough) to create an erupting volcano. Just Google the phrase "baking soda volcano" and have fun!
