SHS3 General Science · Semester 2 Week 19: Technology in Local Industries

Lesson notes

Learning Objectives

Indicator: 3.4.2.LI.1 - Analyse the scientific processes involved in indigenous texture production.

By the end of the lesson, learners can:

Sequence the major stages of gari production in the correct order, from cassava harvesting to the final sieved product.
Explain the scientific principles (fermentation, pressing/dewatering, gelatinisation, and drying) that operate at each stage of gari production.
Discuss the economic importance of gari production to individuals, communities, and the nation of Ghana.
Analyse the role of technology, both traditional and modern, in improving the efficiency and quality of gari processing.
Present findings from a field visit or group discussion using digital tools (camera or voice recorder) to document the gari production process.

Exemplars (from the NaCCA curriculum)

Experiential Learning:
- Visit a gari processing site in your locality to get first-hand information on how gari is produced.
- Put learners in mixed-sex or mixed-ability groups to discuss their findings from the field trip and write reports. Provide opportunities for learners to actively listen to others' views.
- Using diamond 9 discussion, learners enumerate the economic importance of gari and present ideas in class for discussion.
Teaching and Learning Resources:
- Camera
- Voice recording device
- Pen
- Notebooks/pads.
- Charts and pictures of people at a gari processing site
