Week 1: Clay (Part 1) – What is Clay?
💡 Teacher's Overview & Guide
- Subject: Basic Science and Technology
- Class: Primary 2
- Term: Third Term, Week 1
- Duration: 40 Minutes
- Instructional Materials: Samples of wet clay soil, dry molded clay block, sand, garden soil, water in a small bowl.
- Textbook Guide: Refer to the introductory chapter on "Types of Soil: Clay" in the approved textbook.

- What is Clay & Where Found: Explain that clay is a special type of fine soil. Point out where it is found: riverbanks, deep farmlands, and clay pits.
- Properties of Clay: Let pupils feel wet clay and observe dry clay:
- When wet: Soft, sticky, smooth, and easily molded into shapes.
- When dry: Becomes hard, firm, and holds its shape.
- Difference from Other Soils: Demonstrate how sand falls apart easily while wet clay sticks together firmly without falling apart.
- Class Activity: Guided tactile exercise—pupils touch and feel wet sticky clay, then examine dry clay blocks.
