Read this recent news item from Science magazine:  How an ancient cataclysm may have jump-started life on Earth

https://www.sciencemag.org/news/2019/01/how-ancient-cataclysm-may-have-jump-started-life-earth >

What are the connections among our study of matter, astronomy, and earth cycles? What do you understand of the article? What are your questions?

Follow this method of reading a difficult text. This method focuses on what you DO Understand and not on what you do not understand. Even if you only follow a fraction of the meaning, your understanding will grow. By using your questions, you will direct your mind toward essential ideas. This method works for anyone. But you must read straight through and summarize. While this may seem time-consuming, it is very effective. Your reading and understanding will begin to grow. If you keep it up, the growth will even accelerate.

  1. Read two or three paragraphs at a time straight through. Do not stop to look up words.
  2. After reading the selected section of the article, write a summary without looking at the article. Write major questions that you have.
  3. Reread the section. Look up only words that you think are critical for understanding.
  4. Add to your summary. Do not erase or delete
  5. Share and compare with a partner or trio from your most recent group.
  6. Continue with this process for the rest of the article.


Prepare an annotation.

Discuss with the entire class.


You will be assigned to a group to review and analyze references related to Carbon and the Carbon Cycle (everyone watch this short video: https://www.youtube.com/watch?v=nzImo8kSXiU). Think of the ways that carbon is a building material in nature and in human technology and the ways carbon is a fuel. Be careful about using the term “carbon” to designate any carbon compound. That can lead to confusion. For example, carbon dioxide is a compound of the elements carbon and oxygen. Sometime’s people abbreviate the discussion and use the term carbon without clarifying that they are referring to carbon dioxide. Remember that the properties of elements are not the same as the properties of the compounds (molecules) they make.

Work together to help each other examine, analyze, and try to understand your cluster of references. Identify important concepts–big ideas and significant details. Identify essential terms–discuss what they could mean from the context–rather than look up definitions that may be out of context. Identify questions you have and that your classmates are likely to have. Which parts of your references may prove confusing for your classmates? Why do you think so?

Prepare a 5 minute presentation based on your references that captures the main ideas and significant supporting examples. Find out what you can about the background of the references. (Who, how, what, why, etc.) Discuss how the references relate to what you already know about matter. Present the most important questions that you and your group have. What do you and your group suspect the point of view of the author(s) to be? Why? Identify bridges AND barriers to deeper understanding of the topic.
