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 = The cycle processes represented in the model are condensation and evaporation. With the warm water evaporating water vapor, it produced condensation under the lid of the canning jar.

 

 

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

 

Answer = The processes I see not represented in the model are; sublimation, precipitation, transpiration, infiltration, surface run off, and percolation. The way to improve or include the processes would be to add sand and soil to the experiment.

 

 

  1. 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 =

 

Table 1: Infiltration Observations
Sample Observations at 1 Hour Observations at 12 Hours
Sunny Location    
Shady Location    

 

 

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

 

Accept/reject =

 

 

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

 

Answer =

 

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

 

Answer =

 

 

  1. 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?

 

Answer =
