SHS2 Agriculture · Semester 1 Week 16: Modern Mechanised Agriculture

Lesson notes

Learning Objectives

Indicator: 2.2.2.LI.3 - Demonstrate the skills in the operation of simple harvest and postharvest implements and machinery use in Agricultural production.

By the end of the lesson, learners can:

Demonstrate the correct grips, stances, and safe handling techniques for at least three simple harvest tools (sickle, cutlass, hoe) and two post-harvest tools (go-to-hell, chisel) in a practical session.
Perform the correct operational procedure for threshing, winnowing, or shelling a harvested crop using available simple tools, explaining each step as they do it.
Identify and apply the key safety rules for operating harvest and post-harvest implements, including proper body positioning, tool maintenance, and awareness of others in the work area.
Compare the efficiency, advantages, and limitations of manual harvest and post-harvest tools versus mechanised alternatives, and justify which tool is most appropriate for a given farm scenario.
Work collaboratively in mixed-gender groups to operate simple tools, with each group member, including female learners and learners with disabilities, actively performing at least one operational task.

Exemplars (from the NaCCA curriculum)

Collaborative learning: Learners in gender-based groups surf the internet for information on the operations of a simple harvest, post-harvest and storage tools, implements and machinery in Agricultural production and discuss their findings.
Project based learning: Learners in mixed-gender groups demonstrate how simple available tools and equipment are used in performing harvesting, post-harvesting and storage activity in Agricultural production. Teacher should encourage female learners and learners with disabilities to operate the available simple tools and equipment to the best of their ability.
- Sprinklers, watering cans, pipes, irrigation tiles, drip irrigation lines, overhead water tank, dugout etc.
Assessment (2.2.2.AS.3). The document marks these depth-of-knowledge levels for this indicator: Level 4 Extended critical thinking and reasoning.
