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.

1. Repeat steps 1–3 for all other locations.
2. Use these results in your lab report to help you assess CO₂ concentration trends from 1990 to 2005.

Part II: Write a 1-page lab report using the following scientific method sections:

• Purpose
• 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
• 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
• 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
• Provide here any results or data that were generated while doing the lab procedure.
• Discussion/Analysis
• In this section, state clearly whether you obtained the expected results, and if the outcome was as expected.
• Note: You can use the lab data to help you discuss the results and what you learned.

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.

For each assignment, you will use the M.U.S.E. link to complete the lab. Access the M.U.S.E. by clicking on Learning Materials.

In this lab, you will gather data about CO₂ emissions using the National Oceanic and Atmospheric Administration Web site (Earth System Research Laboratory, n.d.) to help you write up a scientific report centered around known phenomena of CO₂ emissions, related to the following question:

• Would you expect to see an increase or decrease in CO₂ emissions in the data over the past 40 years? Why?

Using the M.U.S.E. link, review the background information, and access the Web site to gather your data.

Use the Lab 3 worksheet for assignment instructions and data collection.

This assignment will also be assessed using additional criteria provided he
