Lesson notes

Learning Objectives

Indicator: 1.2.1.LI.1 - Outline the uses and maintenance procedures of measuring tools used in Agricultural production.

By the end of the lesson, learners can:

List at least eight measuring tools used in agricultural production and state one primary use for each.
Explain the correct procedure for using at least four common measuring tools, including tape measures, weighing scales, measuring cylinders and thermometers.
Describe the maintenance procedures for at least three measuring tools, including cleaning, storage and calibration.
Identify safe handling practices when using measuring instruments in the field and laboratory.
Categorise measuring tools according to what they measure (length, weight, volume, temperature, etc.).

Curriculum details

Strand: Modern Technical and Mechanised Agriculture (Strand 2)
Sub-strand: Modern Technical Agriculture (2.1)
Content standard: 1.2.1.CS.1 - Demonstrate knowledge, understanding and skills of measurements, measuring tools and their uses in Agricultural production. 1.2.1.LO.1 Use the knowledge and skills acquired in measurements to determine the physical attributes of Agricultural inputs and produce.
Indicator: 1.2.1.LI.1 - Outline the uses and maintenance procedures of measuring tools used in Agricultural production.
Suggested placement: Semester 1, Week 7 (Week 7 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

Think-pair-share: Learners individually list examples of Agricultural tools and instruments and their use(s) and share with a peer. Teacher assists learners with realia/pictures of tools and instruments to help learners list examples of tools and instruments in Agricultural production. The teacher should challenge talented students to list more tools and instruments in Agriculture production that are not part of the realia/pictures provided.
Collaborative learning: Teacher puts learners in mixed-ability/gender-based groups (where applicable) to watch video/pictures on the appropriate uses and maintenance of some tools and instruments in Agricultural activities and discuss their observations in groups. Encourage all learners to take active participation in the activities. Learners with sight or hearing difficulties should be seated in a way they can benefit from the video/picture. Learners should be assisted with leading questions to come up with their observations.
Experiential learning: Learners in their groups, guided by the instructor/technician, demonstrate measurements in the laboratory and field using the measuring instruments provided. Encourage all learners to take active participation in the activities. Learners with difficulties in using the tools and instruments should be given the necessary support. All safety protocols in the laboratory and the field should be strictly observed.
Assessment (1.2.1.AS.1). The document marks these depth-of-knowledge levels for this indicator: Level 2 Skills of conceptual understanding; Level 3 Strategic reasoning.
