In order for students to understand water and its importance, they must first understand the process by which it is produced. This lesson will help students discover how water is created in nature and the path it takes to reach our rivers, streams, and taps. Using the scientific method, students will conduct an experiment that simulates the water cycle.


Students will be able to:
  • Define and explain the water cycle

  • Conduct an experiment using the scientific method

  • Record and interpret observations

  • Form accurate conclusions based on scientific evidence


  • Chart paper

  • Science journals

  • Internet access computers (class set, or one with projector)

  • For model: (for each group)

    • One glass jar with lid
    • soil
    • sand
    • pebbles or small rocks
    • plant
