6.1 Water Cycle review

What causes the water vapor in the air to become liquid water on the side of a cold soda can on a hot summer day?

• The cold temperature of the can causes the water vapor to condense.

• The heat from the sun melts the water vapor.

• The soda can absorbs water from the air.

• The air pressure around the can increases.

Develop a model in Figure 2 to illustrate the relationship between temperature and molecular motion and spacing. 

The two boxes represent zoomed in views of the water molecules. For each box: 

• Draw particles to represent relative spacing of water molecules.

• Use arrow lengths to show relative movement of water molecules.

Use the model to describe what causes the visible water drops on the cold soda can.

(Hint: Use your knowledge of temperature, molecular motion and molecular spacing in your answer.)

Using the Water Cycle Process Bank in Table 1, add processes to the model that cause water to move within the water cycle. 

• For each process, add an arrow in Figure 3 that shows the direction water moves.

• Label each arrow you draw with the following terms: evaporation, infiltration, precipitation, runoff, and transpiration.

In Figure 4 which TWO predictions that describe how the change in land use from forest to paved pavilion area would cause changes to processes in the water cycle.

• Increased surface runoff and reduced infiltration

• Decreased surface runoff and increased infiltration

• Increased evaporation and increased infiltration

• Decreased evaporation and decreased surface runoff

3. Your teacher brought a large block of ice into class today. He gives you the following instructions:

“We got a delivery of ice today, but our field trip isn’t until tomorrow and we will need enough ice to keep beverages cold. You must design and build a container to keep some of the ice from melting, because the school freezer is full. We can only use the materials we have here in the classroom. We want the container to be as small as possible, and we want to save as much ice as we can for tomorrow. It must be built by the end of the class period.”

What is the problem you are asked to solve?

• We need to build a container to hold the ice and keep it from melting.

• How to keep our lunches and pop cold.

• Where to hold the ice.

• How to Make ice cream.
