Learning Objectives

Indicator: 1.4.1.LI.2 - Describe the farm hygiene and sanitation activities in crop production.

By the end of the lesson, learners can:

List at least five distinct farm hygiene and sanitation activities carried out at the farm site and during the various stages of crop production.
Describe the specific hygiene and sanitation activities appropriate for each stage of crop production, from land preparation through to harvest and storage.
Identify the tools, equipment and chemicals used for farm hygiene and sanitation activities and explain the function of each.
Explain the safety measures that must be observed when handling chemicals used for farm hygiene and sanitation.
Categorise farm hygiene and sanitation activities into those done at the farm site and those done during crop production stages, and justify the timing of each activity.

Exemplars (from the NaCCA curriculum)

Initiating talk for learning: In mixed-gender/ability groups (where applicable) learners brainstorm to come up with examples of activities that are carried out to keep their backyard gardens and school farms clean. Guide learners with difficulty with leading questions to help them come up with examples. Encourage all learners to participate. Learners who can provide detailed information should be encouraged to do so.
Collaborative learning: Learners in mixed-gender groups discuss farm hygiene and sanitation activities at the farm site and during the various stages of crop production. Learners then build a portfolio on farm hygiene and sanitation activities at the farm and during the various stages of crop production for assessment. Ensure that all learners actively participate in the portfolio building. Encourage talented learners to take lead roles and also assist learners with difficulties.
Initiating talk for learning: Learners in mixed-ability/mixed-gender groups (where applicable) discuss the tools, equipment and chemicals required for undertaking farm hygiene and sanitation activities at the farm site and during the various stages in crop production. Example: cutlass, rake, dustbins, disinfectants, powered soap, insecticides, fungicides, herbicides etc. Teachers should use pictures or realia of some of the farm tools, equipment and chemicals to guide learners with difficulty to come up with further examples of the tools for maintaining farm hygiene. Challenge talented learners to give more examples. Use probing questions to guide learners to explain the functions of the tools identified. Strict safety measures should be adhered to when handling the chemicals.
