Lesson notes

Learning Objectives

Indicator: 1.2.2.LI.2 - Describe the factors that affect the use of farm machines and power.

By the end of the lesson, learners can:

List at least five factors that affect the efficiency of farm machines and power in agricultural production.
Explain how each of these factors influences the performance and output of farm machines.
Distinguish between human factors, machine-related factors, and environmental factors that affect machine efficiency.
Recommend practical ways to improve the efficiency of farm machines and power sources in a given farming situation.
Justify the choice of a particular machine or power source based on the prevailing conditions on a farm.

Exemplars (from the NaCCA curriculum)

Problem-Based Learning: In mixed-ability groups, learners brainstorm to come up with the factors that affect the efficiency of farm machines and power during Agricultural activities. Teacher should use leading questions to guide learners to identity the factors that affect the efficiency of farm machines and power during Agricultural activities. Gifted learners should be probed further to come up with further explanations of the factors.
Experiential Learning: In mixed-gender/mixed ability groups, learners visit a farm site/ farm machinery workshop or watch videos/pictures on the use of farm machines and power sources, and make recommendations on how the machines can be used efficiently. Teacher should ensure learners observe strict safety protocols at the farm site/ farm machinery workshop. Videos that portray gender biases should be avoided. Learners with difficulties should be supported with leading questions to make recommendations on how the machines can be used efficiently.
