- - - - 1-Key Concepts: People use tools, machines and processes to transform raw materials such as sugarcane into useful products such as sugar (2011, pp.8,57)
      - Inquiry Activity: The learners receive picture cards showing stages of sugar production. In groups, they will arrange the cards in the correct order and identify the tools or machines used at the different stages. The teacher asks them, "What does each tool help the worker do?" and "What might happen if one of the stages is left out?"
    - - 2-Key Concept: Technology involves using materials, tools and processes to design and make products that meet people's needs (2011, p.8)
      - Inquiry Activity: The learners use modelling clay and a reusable rectangular mold to make a model brick. They remove the model carefully, inspect its shape and suggest how they could improve it. The teacher asks them, "How can you make a brick with straight edges?" and "What could you change if your model loses its shape?"
- - - - 1-Key Concept: The plants provide raw materials that can be processed into useful products, such as sugar from sugarcane (2011, pp.8,57)
      - Inquiry Activity: The learners observe a piece of sugarcane and a sample of sugar. They compare the color, texture and appearance of the two materials and draw a before-and-after picture. The teacher asks them, "What differences can you see between the two objects?" and "How do you think the sugarcane becomes sugar?"
    - - 2-Key Concept: Natural materials from the earth, such as clay, can be processed to make useful products, such as bricks (2011, pp.8,57)
      - Inquiry Activity: The learners examine damp clay and a finished brick. They describe and compare the texture, shape and firmness of each material, then they draw what they observe on a piece of paper. The teacher asks them, "What changes can you see between the clay and brick?" and "Why do you think bricks are harder than wet clay?"
- - - - 1-Key Concepts: Different people perform different jobs and contribute to producing and supplying goods for communities (2011, pp.8.57)
      - Inquiry Activity: The learners examine pictures of sugarcane farmers, factory workers, brickmakers and builders. They then match the worker to the job and explain how the workers depend on one another. The teacher asks them, "Who helps turn the sugarcane into sugar?" and "What might happen if the farmers could not supply sugarcane?"
    - - 2-Key Concepts: Communities use products made from plants and the earth to meet everyday needs (2011, p.57)
      - Inquiry Activity: The learners investigate pictures of homes, schools, shops and everyday food products. They identify where bricks and sugar are used and explain why these products are useful. The teacher asks them, "Where can you find bricks in your community or at home?" and "How would our community be different if we did not have bricks?"
