  1. Water Cycle Materials: Exploring the Water cycle capture sheet Water cycle Homework sheet

  2. Lesson Objective • I can observe/investigate the movement of water through the different stages of the water cycle • I can determine what drives the water cycle.

  3. Essential Question • What is the water cycle?

  4. Demonstration of the water cycle- Evaporation • What will happen when heat is added to this beaker of water?

  5. Demonstration of the water cycle- Evaporation • What will happen when heat is added to this beaker of water?- It will cause the water to get hot and then evaporate (change from a liquid state to a gas state)

  6. Demonstration of the water cycle- Evaporation • What happens to the water as it receives heat energy from the sun (represented by the burner)?

  7. Demonstration of the water cycle- Evaporation • What happens to the water as it receives heat energy from the sun (represented by the burner)? The water will warm up

  8. Demonstration of the water cycle- Evaporation • What phase is occurring in the water?

  9. Demonstration of the water cycle- Evaporation • What phase is occurring in the water? It is evaporation, when water changes from a liquid to a water vapor

  10. Record your answers: Evaporation • ____________________________ is the source of energy that drives Earth’s water cycle.

  11. Hint

  12. Record your answers: Evaporation • The Sun is the source of energy that drives Earth’s water cycle. • As heat energy was added to the water, it changed state from a ___________ to a _____________. This __________ is also called _________________.

  13. hint (although it’s ACTUALLY invisible)

  14. Record your answers: Evaporation • The Sun is the source of energy that drives Earth’s water cycle. • As heat energy was added to the water, it changed state from a liquid to a gas. This gas is also called _________.

  15. Record your answers: Evaporation • The Sun is the source of energy that drives Earth’s water cycle. • As heat energy was added to the water, it changed state from a liquid to a gas. This gas is also called water vapor.

  16. Record your answers: Evaporation • The Sun is the source of energy that drives Earth’s water cycle. • As heat energy was added to the water, it changed state from a liquid to a gas. This gas is also called _________.

  17. Record your answers: Evaporation • The Sun is the source of energy that drives Earth’s water cycle. • As heat energy was added to the water, it changed state from a liquid to a gas. This gas is also called water vapor. • As more and more energy is added to the water, the water molecules move ______________ and farther apart.

  18. Hint

  19. Record your answers: Evaporation • The Sun is the source of energy that drives Earth’s water cycle. • As heat energy was added to the water, it changed state from a liquid to a gas. This gas is also called water vapor. • As more and more energy is added to the water, the water molecules move faster and farther apart.

  20. Record your answers: Evaporation • The Sun is the source of energy that drives Earth’s water cycle. • As heat energy was added to the water, it changed state from a liquid to a gas. This gas is also called water vapor. • As more and more energy is added to the water, the water molecules move faster and farther apart. • When water vapor is warmer and less dense than the surrounding air, it ______________.

  21. Hint

  22. Record your answers: Evaporation • The Sun is the source of energy that drives Earth’s water cycle. • As heat energy was added to the water, it changed state from a liquid to a gas. This gas is also called water vapor. • As more and more energy is added to the water, the water molecules move faster and farther apart. • When water vapor is warmer and less dense than the surrounding air, it evaporates.

  23. Record your answers: Evaporation • The Sun is the source of energy that drives Earth’s water cycle. • As heat energy was added to the water, it changed state from a liquid to a gas. This gas is also called water vapor. • As more and more energy is added to the water, the water molecules move faster and farther apart. • When water vapor is warmer and less dense than the surrounding air, it evaporates. ***hot air rises!***

  24. Demonstration of the water cycle- Condensation • Where did the water on the outside of the can come from?

  25. Demonstration of the water cycle- Condensation • Where did the water on the outside of the can come from? The can was cooler than the air around it. The water vapor that was in the air cooled and turned into a liquid (condensed).

  26. Demonstration of the water cycle- • What made the mirror fog up?

  27. Demonstration of the water cycle- • What made the mirror fog up? The mirror was cooler than your breath. The water vapor that was in your breath cooled and turned into a liquid (condensed) when it touched the mirror.
