Learning Objectives

Indicator: B3.1.2.1.1 - Identify the uses of everyday materials and link the uses to their properties

By the end of the lesson, learners can:

identify at least five everyday materials (wood, plastics, paper, metals, leather, cotton) from their surroundings and name them correctly.
state at least two uses of each of the everyday materials collected and brought to class.
explain, in simple terms, why a material is used for a particular purpose by linking it to one or more of its properties (e.g., hardness, flexibility, ability to be moulded, strength).
match common products (buckets, cups, books, tables) to the materials they are made from (plastics, clay, glass, wood).
predict what might happen if a material with the wrong property is used for a job (e.g., using paper to make a hammer handle).

Exemplars (from the NaCCA curriculum)

- Show learners pictures and videos of common materials e.g. wood, plastics, paper, metals, leather, cotton, etc.
- Learners collect everyday materials in their environment e.g. wood, plastics, paper, metals, leather, cotton, etc. and bring them to class.
- Learners use think-pair-share to discuss the uses of the materials collected.
- Brainstorm with learners to come out with the uses of the materials in relation to their properties, e.g. metals are used for making car bodies because they are hard, plastics are used for making bottles, buckets, bowls because they can be moulded into different shapes
- Engage learners in an activity to match some products such as buckets, cups, books, tables with their material sources such as metals, clay, glass, wood, plastics.
- Provide a lot of materials for the learners to do more activities.
