Product and Processes: From Clay to Bricks ( Caps Ref: DBE 2011:57)
Natural Science
Sub -Topic1
:Properties of Clay
Concept1
:Understanding clay as a natural earth material
Concept 2
:Observing texture, color, and plasticity of clay
Activity
: Clay Exploration: Provide learners with samples of raw clay. Let them touch, mold, and observe its properties. Discuss how clay changes when water is added and when it dries.
Sub- Topic 2
:Changes in Clay During Brick Making
Concept 1
: Physical changes: from soft clay to hard bricks
Concept 2:
Effects of drying and firing (heat) on clay
Activity
: Drying and Hardening Experiment: Learners make small clay shapes and observe them drying over days. Discuss what happens when clay is heated (use pictures/videos of firing in a kiln).
Social Science
Sub-Topic 1
:The Use of Bricks in Communities
Concept 2
:How bricks contribute to safe and comfortable living
Concept 1
:Importance of bricks in building houses and structures
Activit
y: Community Building Discussion: Learners discuss and draw how bricks are used in their homes or community buildings. They can share stories about houses made of bricks versus other materials.
Sub -Topic 2
: Environmental Impact of Clay Mining
Concept 1
:How clay is obtained from the earth
Concept 2
:Importance of sustainable use and care for the environment
Activity:
Environmental Care Role-Play: Learners role-play as miners and environmentalists, discussing ways to minimize harm when mining clay and how to care for the land afterward.
Technology
Sub-Topic 1
The Brick-Making Process:
Concept 1:
Steps: mining, preparing clay, molding, drying, firing, and storing bricks
Activity
: Brick-Making Simulation: Learners follow a step-by-step process to make “bricks” using clay and molds. They sequence the steps and explain each stage.
Concept 2
:Tools and machines used in brick production
Sub- Topic 2
:Evaluating and Improving Brick Quality
Concept 1
:How to test bricks for strength and durability
Concept 2:
Ways to improve brick-making methods:
Activity:
Brick Testing and Discussion: Learners test their clay bricks by gently pressing or dropping them, then discuss what makes a good brick and how to improve their process.
