Lesson notes

Learning Objectives

Indicator: B6.5.3.1.1 - Identify the scientific concepts and principles underlying the operation of some industries

By the end of the lesson, learners can:

State the scientific meaning of at least four key industry terms: fermentation, evaporation, salting-out, and saponification.
Describe the scientific principle behind the production of at least two local industries (kenkey, salt, soap, gari, or cooking oil).
Observe and record at least three activities during a study visit to a local production centre and link each activity to a scientific concept.
Explain in their own words how temperature, time, or mixing affects the quality of a product such as kenkey or soap.
Work in groups to classify the stages of a production process into the scientific principles applied at each stage.

Exemplars (from the NaCCA curriculum)

- Learners watch a video of kenkey and salt production processes.
- Learners go on a study visit to a local business venture such as kenkey, soap, salt production, cooking oil, or gari production centre.
- Learners must observe the activities and interact with people at the workplace.
- Engage learners, in groups, to discuss and identify the key scientific principles underlying the operations of the industries visited.
- Build vocabulary of learners by explaining key terms such as evaporation, salting-out, fermentation and saponification.
Project Give learners a project to work in groups to produce yoghurt, kenkey or soap based on the experiences from their study visits.
