In the lessons

In science lessons carbonated drinks show a gas dissolved in a liquid: when you open the bottle the pressure drops and bubbles escape. In health lessons many carbonated drinks have lots of sugar, which is bad for teeth. Everyday words: fizzy (UK), sparkling, soda or pop (US), soft drink.
