Read “Lab 5: Weather and Climate Change.” This lab will allow you to explore the water cycle through the creation of an ecosystem model. Additionally, you will observe how water moves throughout the environment and is affected by weather patterns. Then, you will utilize this information and your eScience lab kit to complete Demonstration 1and Experiment 1 on the Week Five Lab Reporting Form. Make sure to complete all of the following items before submission:
Lab 5 – Weather and Climate Change
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.
