Smog / Global Climate Change / Thinning of the ozone layer

Nov 22nd and Nov 25th - Lesson 13 - What atmospheric problems have we created?
  1. Use Smog Student Outlines to create Smog Class Outline
  2. TaskVideo - Brainpop on ozone
  3. Class Outline of Thinning of the Ozone Layer
  4. Atmospheric Questions from Tests - How can we find and summarize ideas from texts? Block 8 Block 6
  5. How the Earth Made Us - Human Planet (31:30 - 39:00, 48:50 - 52:40)
  6. Essay Writing Tips (at the bottom of the document)
  7. In-class Essay - Sources (to be projected during the in-class essay)
Content: Students will
  1. Carbon Cycle
    • Describe the carbon cycle; the movement of a carbon atom from the atmosphere through a plant, animal, and decomposer, and back into the atmosphere.
      • cycle
      • states of matter
    • Compare the rate at which CO2 is put into the atmosphere to the rate at which it is removed through the carbon cycle.
    • Analyze data relating to the concentration of atmospheric CO2 over the past 100 years, and describe international efforts to protect the atmosphere.
    • Describe events and the effect they may have on climate (deforestation, glacial melting, and an increase in greenhouse gases).
    • Describe the benefits of Earth’s resources, air and trees.
    • Identify ways that humans affect the atmosphere and the oceans and their limited capacity to absorb wastes and recycle materials naturally.
    Skills:
    • Students will summarize information from texts.
    • Students will cite works and use in-text citation.

      We watched a video on the thinning of the ozone layer, which helped us understand more about why it is thinning and how. The questions below are some questions we answered while watching.



      • What’s the problem? The ozone is thinning because of chemicals and the pollution that we are making in the air. The sun light will get through the layer more stronger if the ozone layer is not there. Which can cause very dangerous UV rays, and it will be easier to get skin cancer or severe sun burns.

      • What is causing the problem? We are causing the thinning to happen by using chemicals in the air that is causing the layer to thin. Pollution is also another way that the ozone layer will thin.

      • What are people doing to solve the problem? We are using less electricity and trying to reduce the amount of pollution in the air. Some chemicals are not being made in factories anymore because some of the are also dangerously thinning the ozone layer

      • How is nature acting to solve the problem? The wind can blow the smog away if it is strong enough. Also photosynthesis from trees remove certain gases like CO2 and many others.

        Task:
        1. Choose a book (maybe with a partner).
        2. Choose a question from the book you have.  The answer is near the question.  Each person must do at least one question.  
        3. You may work together to find the answers.  
        4. Respond to the question on this document.
        5. Include at least one fact with one in-text citation.  
        6. The question are of three types:
          1. The red leaves have questions related to global climate change.
          2. The brown leaves have questions about the thinning of the ozone layer.
          3. The orange leaves are questions about smog.
          4. The yellow leaves are general air pollution questions.

        To find the answers to the questions use the following techniques:
        1. Read the question carefully.  Ensure you understand all the words in the question by using a dictionary or clarifying the questions with your partner.
        2. Scan the question for the subject.  Scan the pages to find sections that match the subject.  Read those sections.

          At the end of class we watched a video on how Smog and Global Climate changes effects the world. It also explained more about the ozone layer thinning and then effects it will do to us and the animals.

  1. Isabela,
    Great post! Your post was very good, but it did not contain a lot of information. At the end of your post, I saw that you said that at the end of the class we saw a video, but you did not leave the video link so we could see what you where talking about. I think in your post, people who where absent to class, will not know what to watch because you did not link the video. I think your post is good, but I think you should work on putting more information. Another thing I would suggest, would be to put more images. More images engages the audiences, so it would be a good idea if you put more pictures.

    Thanks,
    Ana Karen
