Week 1: Earth Moon System

 

  1. What did you do in lab today? In lab, we talked about why we have seasons. We specifically talked about how the seasons work based upon direct sunlight and how much sunlight is hitting the surface of the earth at a certain time. We discussed how seasons happen when direct sunlight hits a tropic (northern and southern line).       
  2. What was the big question? The big question that we were answering these 2 days was "Why do we have season?" 
  3. What did you learn in Thursday’s discussion? In Thursday's discussion, we also discussed why we have seasons, specifically talking about how being closer to the sun does NOT mean it is warmer. We specifically discussed Aphelion, which happens around July 5th, and how the earth is 94,500,000 miles from the sun; and Perihelion, which happens around January 4th, when the earth is 91,400,000 miles from the sun. 
  4. Read the online textbook chapter:                                                                                  What did you learn?​ I learned that solstices occur when one of the tropic lines is directly in line with the sun. This means that winter solstice occurs when the tropic of Capricorn is in line with the sun, and Summer solstice occurs when the Tropic of Cancer is in line with the sun.                                                                                                                                     What was most helpful?​ I found the straight forward definitions and explanations to be most helpful. For example, starting the chapter by saying "Earth's axis is tilted, so different areas are tilted toward the sun at different times of year, causing seasons" was a very simple and straight forward way of explaining seasons in my opinion, which aided my learning process.                                                                                                                What do you need more information on?​ I am still a little confused about shadows and would like to learn more about how to tell which direction your shadow would be facing. Although the textbook and video discussed shadows, I still feel a little confused about this concept. 
  5. What questions, concerns, and/or comments do you have? I would like to know additional information I can utilize to learn more about how to know which direction a shadow would face.
