Kitchen chemistry: fizz, foam and fountains
How can we tell when a new substance has been made?
Eight lessons. Students blow up balloons with yeast, test kitchen liquids with indicator strips, follow what happens when bicarb meets vinegar, and make sherbet and lemonade. Two lessons are teacher-only demonstrations (elephant toothpaste and a cola and mint fountain) that students watch, measure and explain. The topic ends with a two-part project: students research and plan their own simple experiment, then test their ideas and share their findings.
