Lab 5 – Demonstration 1: Modeling the Water Cycle

In this experiment you will observe how entrapped water moves from land to the atmosphere and determine how weather conditions affect this movement.

POST-LAB QUESTIONS

1. Which water cycle processes are represented in this model, and what component of the model represents that process?

Answer =

2. Which processes are not represented? Propose a change to the model in which two of these processes would be included.

Answer =

3. How would the processes in question 1 be altered by an increase or decrease in temperature?

Answer =

Experiment 1: Assessing Infiltration

In this experiment, you will observe how entrapped water moves from land to the atmosphere and determine how weather conditions affect this movement.

POST-LAB QUESTIONS

1. Develop a hypothesis predicting the effect of sunlight on evaporation.

Hypothesis =

2. Would you reject or accept your hypothesis? Why?

Accept/reject =

3. What parts of the water cycle are represented in this experiment?

Answer =

4. How would adding more sand to the bag affect the amount of water vapor released?

Answer =

5. As a period of drought begins, how would infiltration and condensation change initially? What would happen to these two processes as the drought continues over time?
