Fizzy Shamrocks

When baking soda is mixed with vinegar, something new is formed.

The mixture quickly foams up with carbon dioxide gas. If enough vinegar is used, all of the baking soda can be made to react and disappear into the vinegar solution.

This reaction occurs because sodium bicarbonate and acetic acid reacts to carbon dioxide, water, and sodium acetate.

To tie this in with our shamrock theme, we created our very own fizzy shamrocks!

Using a play dough mat, eye droppers, vinegar, and baking soda, students observed what happens when different ingredients are combined.

The result was spectacular!
