The Atmosphere and You Lab Report Instructions: Record your observations in the lab report below. You will submit your completed report. Name and Title: Include your name, instructor's name, date, and name of lab. Objective(s): In your own words, what was the purpose of the lab? Hypothesis: In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment. Procedure: Complete your hypothesis (above). Identify the independent (test) variable and the dependent (outcome) 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. Year Carbon Emissions (gigatons) Temperature (Fahrenheit) 1960 4.2 57.2 1970 5.8 57 1980 6.2 57.4 1990 7.8 57.6 2000 8 58 2010 9.8 58 Maintain carbon dioxide emissions at 9.8 for the rest of scenario one. 2020 2030 2040 2050 2060 2070 2080 2090 2100 2110 Scenario Two: Carbon dioxide emissions decrease Set the c
