Water Cycle-we will draw at the end!

Quiz your partner

• What are the parts of the water cycle that were in the drawing. Can you describe them?

Factors increasing the rate of evaporation

• 1. Higher temperature• 2. Faster air movement (wind)• 3. More Surface Area (spread

out)

Water changes from a liquid to a gas is called evaporation.

Once water evaporates and turns into vapor in the air, can you see it?

On a humid day is this evaporation or condensation?

Quiz your partner

• What is evaporation? • What is produced because of evaporation and

can you see it? • What are the three factors that increase the

rate of evaporation.

Write on your notebook

• 1. Where do the water droplets on the surface of the first bottle come from?

• 2. Why do water droplets not form on the surface of the second bottle?

Water changes from a gas (water vapor) to a liquid is

called condensation

How does dew form?

Do you know how clouds form?

Watch the demonstration w muddy water is cleaned through

infiltration.

• In your notebook, draw and describe what happened. Label it with “infiltration”.

Water soaking into ground is called infiltration.

Do you know where underground water comes from?

How does groundwater get cleaned?

Run-off is when the water moves along the surface of the land and goes into

bodies of water.

Surface Run-off can carry pollution.
