Children have been fascinated with volcanoes lately. So, we have been reading a lot of books about volcanoes, and it seems that scientists are still learning what causes volcanoes to erupt, without being able to predict exactly when would the next volcano blow its top or split its sides. But there are three things we know for sure: volcanoes are beautiful, they are dangerous, and they are the nature's incredible ๐ฅ fireworks!
So, today, we are conducting an erupting ๐ volcano science experiment.
What you will need:
- vinegar,
- red and yellow food coloring,
- baking soda,
- short beaker,
- recycled paper towel cardboard,
- modeling clay,
- marbles, stones, tree bark and moss,
- a tray.

This baking soda and vinegar chemistry project is a fun way to stimulate a real volcanic eruption! Children would take turns pouring red and yellow vinegar into the beaker which has baking soda in it, causing a chemical reaction, which produces orange bubbling "lava."
Baking soda + vinegar โ carbon dioxide + water + sodium ion + acetate ion.
