Activity Title: “Using NetLogo to Explore Concepts of Air Pollution and Its Effects on Population” – Part 2

Learning Objectives: After this lesson youwill be able to:

• Interpret NetLogo code to answer specific questions about the Pollution Simulation
• Use logical reasoning, knowledge of pollution and its associated elements, and knowledge of NetLogo coding to introduce a new element (bicycles) into the simulation

Introduction/Motivation:

What did you learn from the simulation used in Part 1 of this lab? One way emission can be lowered is for some people to use bicycles instead of cars. Not everyone will use bicycles, but if a certain percentage of the population did, what would be the result? In this lab you will work with a partner to alter the code of the NetLogoPollution Simulation to add the use of bicycles.

Materials List:

• Computer
• NetLogo Software (already installed on computer)
• Pollution Simulation (NetLogo)

Procedure:

Use the data you collected in Part I of the NetLogo Pollution Simulation to complete the following lab activity.

1. If you eliminate all factories and run the simulation, the people still die. Run the simulation at least 5 times without pollution (default settings for everything else) and record how many years it takes for all the people to die.

Click on the “Code” tab in the simulation. Look at the code and see if you can figure out why this happens even though there’s no pollution. Explain.

1. If you run the simulation with only population and birthrate selected, sometimes all the people die and sometimes they don’t. Why is this? (Use specific examples from the code.)

1. If people rode bicycles instead of driving cars, harmful emissions would be reduced which would result in lower overall pollution. Alter the code of the simulation to add bicycles. Be sure to include:

A different “turtle”

A different color

Add a bicycle slider to the control window

Add a mechanism to create bicycles

Add a plot line for bicycles

Add a mechanism for bicycles to “die”

Add a procedure to reduce pollution in patches with bicycles

BONUS

In the simulation, trees are set to live only 50 years. Alter the code to make the trees live 100 years.

WHEN YOU ARE FINISHED, save the new simulation you created and follow the teacher’s instructions for submission.
