  1. 1Objects, Materials, and Their UsesDiscover how everyday objects are built from materials and why the right material must match the job an object needs to do.
  2. 2Grouping and Classifying MaterialsLearn how classification turns a mixed collection of objects into meaningful groups based on shared properties.
  3. 3Appearance, Lustre, Hardness, and SoftnessUse careful observation and simple tests to compare materials by shine, texture, hardness and softness.
  4. 4Transparent, Translucent, and Opaque MaterialsCompare how materials transmit light and learn to classify them by whether objects can be seen clearly, vaguely or not at all through them.
  5. 5Soluble and Insoluble MaterialsInvestigate what dissolves in water, what remains separate, and why solubility matters in everyday life and living systems.
  6. 6Mass, Volume, and MatterConnect heavier and lighter objects with mass, occupied space with volume, and both ideas with the scientific meaning of matter.
  7. 7Chapter Summary and PracticeBring the whole chapter together by connecting material properties, classification, matter and real-world material choices through mixed reasoning and practice.
