Lab Assignment- Weather and Climate Change
Lab- Demonstration: 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?
2. Which processes are not represented? Propose a change to the model in which two of these processes would be included.
3. How would the processes in question 1 be altered by an increase or decrease in temperature?
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.

2. Would you reject or accept your hypothesis? Why?
3. What parts of the water cycle are represented in this experiment?
4. How would adding more sand to the bag affect the amount of water vapor released?
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?
