Name ___________________________________________ Hr_____________ Seasons Virtual Lab Learning Objectives: To identify the relationship between the tilt of the Earth, latitude, and temperature and explain how these work together to make seasons. Go to the Seasons Interactive: http://sepuplhs.org/middle/iaes/students/simulations/sepup_seasons5.html On the Introduction page, fill out the following information: Define the following: • Equator • Latitude • Tropic of Cancer • Tropic of Capricorn Fill in the latitudes of some other locations: Circle if this location is in the Northern, Southern Hemisphere, or close to the Equator. North Pole: Northern Southern Equator South Pole: Northern Southern Equator Chicago, Illinois: Northern Southern Equator Anchorage, Alaska: Northern Southern Equator Quito Ecuador: Northern Southern Equator Melbourne, Australia: Northern Southern Equator Continue to the Interactive page, fill out the following information: Part 1: Distance from the Sun Record the distance (in km) of the Earth from the sun in each of the months. January: July: February: August: March: September: April: October: May: November: June: December: *Circle the month(s) when the Earth is the farthest from the sun. Put a square around the month(s) when the Earth is closest to the sun. Analysis and Conclusion: Watch the video: https://www.youtube.com/watch?v=Pgq0LThW7QA At 1:20 in the video, the Bison incorrectly tries to explain why we have seasons based on Earth’s distance from the sun. What was his CLAIM? Why is his claim incorrect? Use data from the video and your table above. Stay on the Interactive page, fill out the following information: Part 2: Temperatures Fill in the data table below with the temperatures of the locations for each season. Location Temp Summer (June) Temp Fall (September) Temp Winter (December) Temp Spring (March) Chicago, Illinois Anchorage, Alaska Quito, Ecuador Melbourne, Australia 1. What two factors affect the temperature in each location? _________________________________ AND ______________________________ Part 3: Earth’s Tilt Click to show Tropics/Equator 1. What is the angle of Earth’s tilt? 2. Click to go through the months. Does the tilt of the Earth change? 3. Observations: As you click through the months, observe the picture. Answer each question below with: Equator, Northern Hemisphere, Southern Hemisphere. • In January, which receives the most direct sunlight? ___________________ • In July, which receives the most direct sunlight? ______________________ • In March (and September), which receives the most direct sunlight? ___________ 4. Fill in the table below for each city. Click on each city to show its location on the globe. City Month with longest daylight hours Month with shortest daylight hours Anchorage Chicago Quito Melbourne Watch this video to review how the tilt of the Earth affects the amount of daylight: https://www.youtube.com/watch?v=eUsWUiVCq5U 5. Why do you think Quito, Equator has very little changes to the daylight hours throughout the year? 6. In what month is the Northern Hemisphere most tilted toward the Sun? 7. In what month is the Northern Hemisphere most tilted away from the Sun? 8. Explain how the tilt of the Earth affects the seasons and daylight length.
