In this activity, you will create an experiment and use the Smog City simulator to run the experiment. 

PART 1: SMOG CITY EXPERIMENT      Word version of lab:link to a local webpage

  1. Access the Smog City web site.
     
  2. Select and click on “Run Smog City” from the left-side navigation bar.

 

  1. Once Smog City loads to your computer, take note of the following areas of Smog City, including Weather Condition, Population Level, and Emissions Levels. All areas have “clickable” choices. Mouse-over or click on the choices.
  2. Click the Red “Reset” button.
     
  3. Look at all the choices again. Notice how each of the choices are pre-set to a certain level. These are called the default settings. In the chart below, circle or highlight the default setting for each choice. The first setting, Maximum Daily Temperature, has already been completed for you.

  1. Click the Red “Reset” button to make sure that the defaults are set.
     
  2. Click on the Green “Start” button. Record what happens in the table below.

Level 1

 

 

  1. Turn only the Cars and Trucks dial up to 2. Leave all other settings alone as illustrated in the chart below.
     
  2. Click the Green “Start” button and record what happens in the table below. Continue to change the settings and record the results in the table below.

·         Which type of emissions had the greatest affect on ozone levels?

 

  1. Now that you are familiar with the basics of Smog City, you are going to design your own experiment. The experiment will involve changing the Population Level and Emissions Levels, choices that humans have control over. The experiment must be typed in the Scientific Method format. The explanations below may help you with your experiment.

PART 2: GROUP DISCUSSION
Discuss the experiment you performed with 5 other people that completed the experiment and then answer the following questions: (summarize your own answers)

 

  1. Was there any one variable that seemed to have a greater increase in smog than others tested? Which one?

 

 

 

  1. What steps could be taken to control Emissions Levels?

 

 

 

  1. Can you think of ways to reduce ozone levels?

 

 

 

  1. How could a population increase occur without an increase of emissions?
