Lab Assignment la INSOLATION AND TIME Objectives: 1. To learn about the relationship between the earth and the sun. 2. To understand the effect of latitude on insolation. 3. To better understand the idea behind time zones. Part I: Earth-Sun Relations How does the earth relate to the sun? How does our tilt affect the seasons we experience? The fact that we are currently tilted on our axis by 23.5° influences how much sunlight each place on earth receives. We call this sunlight incoming solar radiation, or insolation. We will investigate the relationship between latitude and insolation received in this lab. computer Supplies: writing utensil Procedure: Go to the following website and use it to answer questions 1-6. 1. What latitudes (approximately) are receiving sunlight on June 21? 2. Which latitude (approximately) appears to have the direct sunlight on June 21? 3. What did you notice about what places received sunlight throughout the revolution? The Sunlight stops at the Antarctic Circle and the Arctic Circle. 4. Having lived on earth your whole life, you are familiar with the seasons we experience (especially if you are from the Midwest). How would the seasons change if we weren't tilted on our axis?
