Lessons in this chapter

  1. 1Three States of WaterExplore why ice, liquid water, and water vapour behave differently while remaining the same substance.
  2. 2Where Does Disappearing Water Go?Investigate puddles and wet surfaces to discover how liquid water enters the air.
  3. 3Why Do Droplets Form on a Cold Glass?Test where droplets on a chilled glass come from and learn how vapour returns to liquid water.
  4. 4How Heating and Cooling Change WaterConnect melting, freezing, evaporation, and condensation in one state-change model.
  5. 5What Makes Evaporation Faster or Slower?Design fair comparisons to see how surface area, warmth, moving air, and humidity affect drying.
  6. 6Cooling Through EvaporationExplain why wet skin and earthen pots become cool, then design a simple pot-in-pot cooler.
  7. 7From Clouds to the Water CycleFollow water from Earth’s surface into clouds and back, and consider why usable water needs care.
  8. 8Summary & PracticeConnect every state change, investigation, weather process, and water-use decision in one chapter review.
