“Phases of Water” Brain pop
  • Draw a picture of H20 molecules in a gas, liquid, and solid (in that order)
    • Act it out!
water molecules
Water Molecules

Water is made up of molecules . Water changes state (gas, liquid, solid) when it’s molecules are heated or cooled.

molecules
Molecules

Water molecules become less dense when heat is added. This happens when water changes from ice to liquid or from liquid to gas.

Water molecules become dense when in cold temperatures. This is seen when water turns to ice or changes from a gas to liquid.

Add Cold

Add Heat

What is happening to the molecules?

Turn and Talk.

Draw what you think the molecules look like at each stage of the water cycle.

THE WATER CYCLE

(Hydrologic Cycle)

today s objective
TODAY’S OBJECTIVE
  • At the end of today’s lesson, you should be able to define components of the water cycle. (evaporation, condensation, precipitation, groundwater, transpiration, accumulation)
nature s cycles
NATURE’S CYCLES
  • Earth’s resources move through ecosystems in cycles.
  • Some of the most important cycles are:

-Nitrogen Cycle

-Carbon Cycle

-Water Cycle

  • All living things depend on water, carbon and nitrogen to carry out their life processes
the water cycle pg 15
THE WATER CYCLE (pg 15)
  • Water Cycle: The change of water from one state to another and its movement from one place to another on Earth
  • The changes and movement of water during the water cycle are driven by the sun’s energy
the water cycle1
THE WATER CYCLE

1

  • The main source of water=oceans.

Every day, trillions of liters of water evaporate from the ocean

  • Water also evaporates rivers, lakes, and other sources on land. Plants give off water vapor as well (transpiration)
evaporation
Evaporation
  • Evaporation is the process by which a liquid changes into a gas, or water vapor
transpiration
Transpiration

Transpiration is the release of water vapor into the air from a plant’s leaves

condensation
Condensation

Condensation is the change of state from water vapor to liquid.

  • Water vapor cools and condenses into tiny water droplets. Bunches of tiny droplets collect into clouds

THE WATER CYCLE

4

  • Water from clouds fall back to earth’s surface as precipitation.
precipitation
Precipitation

Precipitation is any type of water that reaches the Earth (rain, snow, sleet, hail)

the water cycle8
THE WATER CYCLE

5

When water reaches the ground, three things happen to it:

1 run off accumulation
1. Run-off/Accumulation

1. Water runs down hills over surface (runoff) and collects in oceans, rivers, lakes, streams (accumulation)

2 groundwater
2. Groundwater

2. Water seeps into the ground

3 evaporation
3. Evaporation

3. Water evaporates back into the air

summary
Summary
  • Water changes from state to state and moves all around the earth in the water cycle and is caused by the sun. The water cycle includes evaporation, precipitation, groundwater, condensation, accumulation, runoff, transpiration.
