Basic 9 Career Technology Term 1 Week 7 Lesson Plan

Show learners a few everyday items made from different materials. Ask learners to identify which ones are made from compliant materials and justify their choices. Share performance indicators with learners.

Concrete-resource task: Set out these resources for each group: Kente fabric offcut; Leather offcut; Raffia strip. Learners inspect and safely handle each item, then use the items in the practical health, food, materials, or workshop task below. Briefly review the properties of compliant materials using examples. Compliant Materials Properties Rubber Highly elastic Resistant to water and many chemicals Good electrical insulator Dampens vibrations Silicone Highly flexible and elastic Resistant to UV, ozone, and extremes of temperature Biocompatible (used in medical devices) Non-reactive and stable Polyurethane (PU) Good abrasion and wear resistance Resistant to oils, greases, and many solvents Can be formulated to be very soft or very hard Available in foam format as well Foams Lightweight Can be compressed and will return to their original shape Good insulating properties Used in mattresses, protective packaging, and more Latex Elastic Biodegradable Resistant to wear and tear Used in gloves, balloons, and many medical products Discuss the differences between compliant and non-compliant materials. Brainstorm potential risks of working with different tools. Discuss safety precautions to be followed. Have learners watch a short video or pictures about safe practices when working with tools and equipment. Teacher demonstrates on how to use tools safely while working with a compliant material. Discuss the importance of safety when working with compliant materials. Divide learners into groups. Give each group a few samples of different materials. Each group identifies which samples are compliant materials based on their properties and presents their findings to the class. Assessment 1. Name two compliant materials. 2. Identify any three compliant materials and state one property of each. 3. Why is it important to follow safety practices? 4. Name one safety precaution when using tools.

Use peer discussion and effective questioning to find out from learners what they have learnt during the lesson

Show learners a simple artefact made from a compliant material. Ask them to guess which compliant material it's made from and its purpose. Share performance indicators with learners.

Concrete-resource task: Set out these resources for each group: Kente fabric offcut; Leather offcut; Raffia strip. Learners inspect and safely handle each item, then use the items in the practical health, food, materials, or workshop task below. Discuss the reasons why the material for the phase1_starter artefact was chosen. Guide learners to identify the factors that influence the selection of compliant materials Example: - Skills of the designer - Temperature Resistance - Chemical Resistance - Purpose/function - Durability and Fatigue Life: - Cost - Availability - Density and Weight - UV Resistance Provide a step-by-step demonstration of how to work with a compliant material, from measuring to surface finishing. Discuss the importance of each step and give tips for best practices. Allow learners to choose a compliant material and design a simple artefact. Learners’ measure, cut, fold, join, and finish their artefacts based on what they learned from the demonstration. Once everyone is done, allow learners to display their artefacts. Learners gather in groups, appraising each other’s work, discussing the materials chosen, and why. Assessment 1. What are two factors to consider when selecting a compliant material? 2. Why is it important to choose the right material for a task? 3. What is an artefact? 4. How can compliant materials be beneficial in creating artefacts?

Take feedback from learners and summarize the lesson.
