Student Pages - Lesson 3 - The Seasons, The Tilt Of The Earth, Day And Night
When you have completed your experiments, use the internet to learn more about Seasons, the tilt of the Earth, and Night and Day.
1. Use Google or Yahoo! to find the following information:
- How long does it take the earth to make one rotation on its own axis?
- How long does it take the earth to make one revolution around the sun?
- The earth is tilted at what degree?
Perform the following calculations based on the information you have obtained:
- How many times does the Earth rotate in one week?
- How many times does the Earth rotate in one month?
- How many times does the Earth rotate in one year?
- How many times does the Earth revolve around the Sun in one decade?
- How many times does the Earth revolve around the Sun in one century?
- How many times does the Earth revolve around the Sun in one millennium?
Use a compass and a protractor to draw an image of the Earth. Divide the circle in half from the top. Use the protractor to draw a line that is 23.5º from the first line.
2. Visit the following website to view current daytime and nighttime areas for the Earth. (Scroll down to the middle of the page) To understand that day and night is caused by the Earth's rotation, repeatedly click on the right arrow for longitude. You will see the Earth rotate as well as the day/night line move. You can also set the Earth in motion by clicking on the "daily" button, then clicking on "animate". Watch as the date changes with each rotation. Click on "Reset to current" to view the current data.
Click on the "Map" button to see the Entire Earth and areas that are experiencing daylight or night.
