1.1.9 LLLLLLLLab - Investigate Your Ecological Footprint (Wet lab) - Google Docs.pdf

Name: Arjun Mahesh, Date: January 13, 2024 In this lab, you will collect data about your life and your resource consumption to measure your current ecological footprint. Then you will calculate a value for your ecological footprint, which represents the amount of land required to provide all the natural resources you use. You will then form a hypothesis about three changes you can make in your lifestyle to reduce your ecological footprint and then calculate the difference those changes would make. Be sure to: Follow safe practices during this investigation. Leave enough time to complete this lab; it will require more than two weeks. Materials Access to the Internet Procedure Part 1: Calculate Your Current Basic Ecological Footprint To prepare for this lab, follow Steps 1 and 2 below to access a quiz that will enable you to calculate your ecological footprint. Review the questions about your lifestyle and habits. 1. Click the "Ecological Footprint Calculator" link on the activity landing page. Then click the image of the computer screen. Choose the correct language in the top right corner. 2. Click "TAKE THE FIRST STEP" on the page that opens. 3. Click through the quiz and make notes about the types of information you will need to accurately respond to each question. Then spend a day or two making

observations about your lifestyle and asking questions of your family and friends to determine your habits. 4. Using the information you gathered, take the quiz to calculate your ecological footprint. For now, ignore the "ADD DETAILS TO IMPROVE ACCURACY" links that follow several of the questions. You will use them in a later section of this lab. 5. Complete the quiz by answering all the questions. Do not close the final window until you are ready to stop working on the lab. You do not need to enter your email address. You can choose "skip to view my results". 6. Explore the Results pages, including the information found by rolling over the orange circles labeled "i." Click the orange arrow to see more of your results. Then answer the questions about the results of your basic ecological footprint quiz in the Data for Part 1 section. Data for Part 1: Your Current Basic Ecological Footprint (9 points) Summarize your results for Part 1 here. 1. What was your personal Earth overshoot day? What does this mean? (1 point) My personal Earth Overshoot day was February 26. This means that by this date if everyone in the world lives like me then earth will run out of resources faster than people are using them. 2. If everyone on Earth lived the way you do (according to the basic information you gave), how many Earths would be needed to provide enough resources? (1 point) 6.4 Earths are required if everyone lives like me.

3. Click the "See Details" link on the Results page, then use the space below to draw the circle graph that appears. Include the numbers of global hectares (gha) that appear as you roll over each section of the graph, as well as the key and labels. (3 points) 4. Summarize the breakdown of your basic ecological footprint by land type. a. How many global hectares (gha) of Earth's area does it take to support you (your ecological footprint)? (1 point) 10.4 b. Rank the different categories of land types you require from greatest to least. (1 point) Carbon footprint, forest products, crapland, built-up land, fishing grounds, grazing lands

c. How many tons of carbon dioxide are produced by your resource consumption? (1 point) 21.1 tons of carbon dioxide d. What percentage of your basic ecological footprint is your "carbon footprint"? (1 point) 70% Part 2: Calculate Your Current Detailed Ecological Footprint Now you will calculate a detailed ecological footprint for yourself. 1. Click the "Retake the Quiz" button or repeat Steps 1 and 2 from Part 1 if you need to log in to the site again. 2. Take the quiz again, but this time, click "ADD DETAILS TO IMPROVE ACCURACY" when it appears and answer the more specific questions. Be sure to save your answers before you advance to the next page. This will give you a detailed ecological footprint. Do not close the final window until you are ready to stop working on the lab. 3. Explore the Results page, including the information found by rolling over the orange circles labeled "i." Answer the questions about the results of your detailed ecological footprint quiz in the Data for Part 2 section. Data for Part 2: Your Current Detailed Ecological Footprint (6 points) Summarize your results for Part 2 here. 1. Record the values for your current basic and detailed footprints in the table. (2 points)

Topic Current basic footprint (values) Current detailed footprint (values) Earth overshoot day 26 feb 24 feb Number of Earths 6.4 6.6 Number of global hectares (gha) 10.4 10.7 Tons of carbon dioxide 23.5 23.5 2. Click the "See Details" link on the first results page, then use the space below to draw the new circle graph that appears. Include the numbers of global hectares (gha) that appear as you roll over each section of the graph, as well as the key and labels. (2 points)
