A refreshing, fermented low-alcohol drink
This recipe-based procedure can be used to introduce younger students to the principles of fermentation, food hygiene (a precursor to aseptic technique) and the biochemistry of respiration. There are also opportunities for more challenging problem-solving activites, some of a technological nature.
Students will learn about food hygeine and fermentation. There are opportunities for additional problem-solving activities.
