Objective(s):
to learn about the atmosphere and how we can help it
Hypothesis:
Carbon dioxide emissions will increase in the next century and global temperatures will increase.
Procedure:
Complete your hypothesis (above).
Identify the independent (test) variable and the dependent (outcome) variable: The emission is the independent variable. The temperature is dependent variable.
Practice using the computer model. Select each marker to see what it does. Here is a summary you can refer back to as you complete your experiment.
Carbon Dioxide Emissions Slider: You will use the arrows to change the amounts of carbon emissions.
Time Step Size: This will allow you to view the data every 5 years or every 10 years.
Start Over: Use this to reset the model if needed.
The current carbon emissions are 9.8 gigatons or 9.8 billion tons. Complete all three scenarios to find out what happens to the global temperature if these emissions stay the same, decrease, or increase over the next century. Follow the instructions in the Data section of this report.
Data:
For each scenario, record the carbon dioxide emission rate and the global temperature. The data for the years 1960–2010 are already filled out for you.
Scenario One: Carbon dioxide emissions stay the same
Set the carbon dioxide emissions rate to 9.8 gigatons.
Set the time step size to 10 years.
Select step forward until you have the data through the year 2110.
Record the data in the table below.

Conclusion:
Use your data to answer the following questions. Use complete sentences, and be as detailed as possible.
Summarize how the carbon emissions affected the atmospheric temperature in each of the three scenarios:
Scenario One: If the carbon emissions stay the same the temperature will still rise.
Scenario Two: If the carbon emissions go down then the temperatures will go up but slowly.
Scenario Three: If the carbon emission goes up the temperatures will also go up faster.
Was your hypothesis supported by your results or not? Explain how you know. Yes, my hypothesis was correct. Because the data shows that as the carbon emissions increase the temperature will as well.
Explain the difference between the greenhouse effect and global warming. Global warming is a change in the earth that is causing it to heat up. The greenhouse effect is a natural change due to sunlight and the atmosphere.
Based on your knowledge of how the greenhouse effect works, why does the level of carbon dioxide affect the global temperature? because the more carbon dioxide the weaker the ozone layer gets cause that's the thing that keeps us safe from all the suns heat
Name three sources of atmospheric carbon dioxide. Three sources of atmospheric carbon dioxide are decomposition, ocean release, and respiration.
