Summary

• Description:

  The PDF document comprises Grade 6 Rationalized Science and Technology Strand 2 Matter Notes.

  It is a comprehensive set of Grade 6 Science and Technology learner notes aligned with the Competency Based Curriculum (CBC). The notes focus on Strand 2: Matter and help learners understand the materials that make up the world around them, how matter exists in different states, and how changes in temperature affect matter. The content uses clear explanations, practical examples from everyday life, diagrams and real-world Kenyan contexts to make scientific ideas easy to understand.

  • Level: Grade 6
  • Subject: Rationalized Science and Technology
  • Strand Covered: Strand 2 – Matter
  • Curriculum: Competency Based Curriculum (CBC)

  It covers the following strands and substrands:

  • Strand 2.0: Matter
    • Sub-Strand 2.1: Change of State of Matter
      • Meaning of matter and its basic properties
      • States of matter: solids, liquids and gases
      • Characteristics and examples of solids, liquids and gases
      • Particle arrangement and behaviour in different states of matter
      • Meaning of change of state and how it occurs through heating and cooling
      • Processes of change of state including melting, freezing, evaporation and condensation
      • Other changes of state such as sublimation and deposition
      • Effects of heating and cooling on matter
      • Applications of change of state in everyday life such as cooking, drying clothes and candle making
      • Importance of change of state in food preservation, agriculture and small businesses
      • Environmental and economic importance of change of state processes
      • Safety precautions when demonstrating heating and cooling experiments
      • Investigative activities and simple experiments related to change of state
    • Sub-Strand 2.2: Composition of Air
      • Meaning and properties of air as a form of matter
      • Air as a mixture of gases in the atmosphere
      • Composition of air including nitrogen, oxygen, carbon dioxide and other gases
      • Importance and uses of oxygen, nitrogen and carbon dioxide
      • Role of oxygen in breathing and combustion
      • Importance of nitrogen in plant growth and fertiliser production
      • Role of carbon dioxide in photosynthesis
      • Water vapour in air and its role in weather and rainfall formation
      • Simple investigations demonstrating the presence of oxygen in air
      • Meaning and causes of air pollution
      • Common sources of air pollution such as vehicle emissions, smoke, dust and burning waste
      • Effects of air pollution on human health, the environment and climate
      • Ways of reducing air pollution at home, school and community levels
      • Importance of clean air for healthy living and environmental conservation
      • Safety precautions in polluted environments

  These notes help learners understand the nature of matter, the processes that change matter from one state to another, and the importance of air in supporting life. The content connects science concepts with everyday experiences such as drying clothes in the sun, cooking food and protecting the environment.
