Assignment: SCIE211 Phase 3 Lab Report
Title: Sources of CO2 Emissions
Instructions: You will need to write a 1-page lab report using the scientific method centered on
the known phenomena of CO2 emissions, related to the following question:
Would you expect to see an increase or decrease in CO2 emission in the data over the past
40 years? Why?
When your lab report is complete, post it in Submitted Assignment files.
Part I: In the Web site link given in the assignment description, you will see an interactive map
of the world titled GMD Measurement Locations. You can zoom in and out and move the map
around within the window. In the map, choose 5 sites that are labeled with a star, which will
have CO2 concentrations. Follow the steps below to fill in the data table:
1. Click on a starred location. (One site will not have CO2 concentrations.)
2. Once the starred location opens, on the right side of the screen, click on the pictured
graph Examples of Data for CO2.
3. Once the graph opens, make a note of the CO2 concentrations from previous years to
present day. Fill in the table below.
4. Repeat steps 13 for all other locations.
5. Use these results in your lab report to help you assess CO2 concentration trends from
1990 to 2005.
Location
Code
Name of City/Country
CO2 Emissions in 1990
CO2 Emissions in 2005
Part II: Write a 1-page lab report using the following scientific method sections:
Purpose
o State the purpose of the lab.
Introduction
This is an investigation of what is currently known about the question being
asked. Use background information from credible references to write a short
summary about concepts in the lab. List and cite references in APA style.
Hypothesis/Predicted Outcome
o A hypothesis is an educated guess. Based on what you have learned and written
about in the Introduction, state what you expect to be the results of the lab
procedures.
Methods
o Summarize the procedures that you used in the lab. The Methods section should
also state clearly how data (numbers) were collected during the lab; this will be
reported in the Results/Outcome section.
Results/Outcome
o Provide here any results or data that were generated while doing the lab
procedure.
Discussion/Analysis
o In this section, state clearly whether you obtained the expected results, and if the
outcome was as expected.
o Note: You can use the lab data to help you discuss the results and what you
learned.
o
Provide references in APA format. This includes a reference list and in-text citations for
references used in the Introduction section.
Give your paper a title and number, and identify each section as specified above. Although
the hypothesis will be a 1-sentence answer, the other sections will need to be paragraphs to
adequately explain your experiment.
When your lab report is complete, post it in Submitted Assignment files.

Part 1:
Introduction
The natural balance that occurs between global atmospheric cooling and warming processes provides an
important contribution to the Earths varied climates.
Troposphere gases
Planetary albedo from clouds low in the troposphere, sulfur dioxide (SO2) from active volcanoes, snow,
and ice all reflect incoming solar radiation back into space. This causes a cooling effect on climates
within a geographical area.
Clouds high in the troposphere and greenhouse gases such as water vapor(H2O), carbon dioxide (CO2) ,
methane (CH4) , and nitrous oxide (N2O) have a warming effect.
Along with the solar activity, these cooling and warming processes help ensure that the planets average
surface temperature is a net value that is above freezing, helping to ensure that life is possible.
Theory on CO2 Emissions
It has been hypothesized that anthropogenic effects (conditions caused by human activity) that are
associated with industry, agriculture, and fossil fuel use have enhanced these warming processes by
contributing greenhouse gases such as N2O, CH4, and CO2 into the troposphere. As a result, CO2 is
believed to contribute the most to the atmospheric warming process.
Pollution
Pollution is a substance that produces a detrimental change in the environment because of its composition
and abundance. Anthropogenic sources of CO2 fit this description because of the perception that there is
evidence of a positive correlation between the increases in anthropogenic CO2 and increases in
temperature. In turn, as temperatures increase, climates can change worldwide, unbalancing ecosystems
across the globe.
Strategies
Strategies and prediction models can be used to decrease or eliminate the effects that are associated with a
particular pollutant. First, the cause of the pollution must be identified. Then, scientists can create
innovate ways to reduce or eliminate its production.
