Fizzing and Foaming - Experiment 1

Today we started off a science unit called Fizzing and Foaming, learning about chemical reactions.  We made sherbet using the following recipe and process:

We learnt when a carbonate, in this case the baking soda, and an acid, the citric and tartaric acids, are mixed together with moisture present, it creates CO2 (carbon dioxide) which are the gas bubbles fizzing on our tongues.  What a tasty way to learn!
