Classroom Ideas

Could be used to illustrate the applications of scientific knowledge (evaporation and distillation) to the food industry. There are opportunities for DT teachers to work with colleagues in Science to develop links to STEM (Science Technology Engineering and Mathematics). Learners might reflect on the benefits and drawbacks of using concentrates, taking into account transportation, storage and consumption, speculating on the impact on cost. As an extension, learners might estimate savings in the storage and transport of concentrates, in a mathematical simulation activity.
