While we were studying rocks and volcanoes during one of our homeschool units, we made a simple volcano using household items. Making a volcano with kids is an easy and fun science activity. Little ones are fascinated by the fizzy "lava" and can't wait to do the activity again.
There are lots of ways you can make a volcano, but I have found it easiest to have something you can place the baking soda in. I cut the small disposable paper cup in half, about 2 inches from the bottom.
He used more playdough to build up around the base and make it look more like a volcano.
Once the volcano is ready, take it outside. Pour a little baking soda into the top of the volcano.
Pour vinegar in a cup.
Add a drop or two of red food coloring.
Pour the red vinegar into the top of the volcano and watch what happens!
Jonah loved this! He has worked with baking soda and vinegar before, but he didn't remember how the two react to each other. He was excited because he was allowed to do all the steps by himself and took ownership of his learning. He wanted to see the fizzing volcano more than once, which led to an afternoon of giggles.
