Earth’s Rotation and Revolution Objectives:  Explain the causes of day and night.  Explain how the tilt of the Earth’s axis causes the change of seasons.

DO NOW:

Do you think men and women have always had equal opportunity in science? (look at the picture on the board – Man on the Moon)

REVOLUTION How long does it take? What does it cause? Details, details!

Independent Practice: 1. Earth’s complete rotation takes about (1) 365 days (3) 6 months (2) 24 hours (4) 1 month

2. Earth’s complete revolution around the Sun takes about (1) 365 days (3) 6 months (2) 24 hours (4) 1 month

3. Day and night are caused by (1) the tilt of Earth’s axis (3) Earth’s revolution around the sun (2) eclipses (4) Earth’s rotation on its axis

4. The length of Earth’s year is related to Earth’s movement around (1) the Sun (3) the Moon (2) its axis (4) its diameter

5. The length of daylight at a location is related to (1) the stars (3) the Moon (2) its latitude (4) its longitude

6. On the picture below, place a “D” on the side of Earth that is experience daylight and an “N” on the side of Earth that is experiencing night. Name: ______Date: ______“Exceed the Highest Expectations!” 7. Earth’s axis is on a tilt of about (1) 24º (3) 365º (2) 23.5º (4) 27.3º

8. Earth’s rotation makes the sun appear to rise in the (1) North (3) South (2) East (4) West

9. What causes the differences in seasons? (1) the angle of the Sun’s rays and the number of daylight hours (2) the tilt of the Earth and it’s revolution around the Sun (3) both 1 and 2 above (4) difference in hemispheres

10. If it is winter in the Southern Hemisphere, what season will it be in the Northern Hemisphere?

11. The complete revolution time of planets around the Sun is given in the table below. Answer the questions that follow the table.

Planet Complete Revolution Time (Earth days) Mercury 88 Venus 225 Earth 365 Mars 687 Which planets are moving more quickly around the Sun than the Earth?

Earth’s seasons last about 91 days (one quarter of a complete revolution). Using this information, approximately how long would a season last on Mercury?

How long would a season last on Mars?
