What Evidence is There That Earth Is Warming More Quickly Than Ever?

Go to this link from the Union of Concerned Scientists, that gives evidence that the planet is warming because of humans, and not just the natural cycle. In groups of two or 3, you will be assigned # 1-10. Click on each topic, write a few basic points and make a simple eye-catching illustration.     ****** Draw a diagram and explain the Greenhouse Effect in your own words. 1. Explain what greenhouse gases are, give some examples of greenhouse gases, and explain where they come from. 2. Explain how greenhouse gases trap heat, and why this process is called the Greenhouse Effect. 3. Explain why we need a certain amount of Greenhouse Effect 4. Draw a diagram to show how it works, use arrows and text to explain the Greenhouse Effect. Use colour to make your drawing more effective. Grading: Explanation /20 Drawing /10 Total /30

How does the number of coils affect the strength of an electromagnet?

Question Hypothesis Materials Procedure Analysis 1. Create a bar graph using the results in your observation table. Include: – Title – label axes (number of coils, number of paper clips) – use ruler, colour 2. Describe your observations in sentences Conclusion a. Answer the original question . b. What do you think would happen if you added additional coils? c. Why do you think you got the results you did?   **********************

The Carbon Cycle and Our Most Important Environmental Challenge

This activity is to familiarize ourselves with the carbon cycle, and global warming (also known as the greenhouse effect).  A good strategy would be to take notes by watching these videos, and thus avoid the tendency of copying and pasting from online sources. By using our own words to interpret information, we can help ourselves to truly understand what we are studying.

Suggested work sequence for Ecosystem Inquiry:

  1. Take notes on your organism, organized by topic with headings.
  2. Create a table of contents for your book, placing headings in logical order
  3. Record your information sources in the bibliography template from the blog. (If you click on the template, open in Pages app.)
  4. Create your ecosystem flow chart
  5. Use as many helpful visuals as possible, including captions to explain relevance
  6. Use hyperlinks to incorporate video and links to other sites
  7. Add your own voice recordings to explain ideas.
  8. Begin thinking of a critical thinking question. We will work on this together.

  1. I don’t get what it means when it said in the electromagnet experiment conclusion, “Why do you think you got these results”.

    • Hi Lorenzo. Your results probably indicated that more coils around the nail made the magnet stronger, so the question is “Why do you think that the electromagnet picked up more paper clips when you added coils to the nail?”

      This is more of a thinking exercise, rather than giving a right or wrong answer. See if you can figure out your own answer or hypotheses to this.
