9. These are example of objects that rotates. Rotation means “to spin.” 

10. How about this picture? What can you say about the car’s movement?

11. How about this picture? What can you say about its movement? The car is moving around the tree The car is revolving around the tree. Revolution means “ to go around something .”

12. ACTIVITY 10.1 Demonstrating Rotation and Revolution  Problem: What is the difference between the rotation and the revolution of the earth?   What you need: Globe Wide area or space Flashlight

13. What you need to do:   Draw a circle to serve as the orbit of earth. Let one person in the group go to the center. He/she will represent the sun. Let one person hold the globe and spin it evenly counter clockwise not too fast, while he/she walks completely around the person at the center of the circle. (As it revolves around the sun, north end of the earth’s axis continues to point toward a relatively stationery object. In the sky, it is called the North Star.) The person at the center is revolving around him/her. Notice the part lighted by the flashlight when the earth rotates sand revolves around the sun.

14. What have you found out?   Do all parts of Earth receive light as it rotate on its axis? Why? What is the effect of Earth’s rotation? What have you noticed about the amount of light received by Earth as it revolves around the sun? What do you think are the occurences when Earth revolves around the sun? Conclusion: Make a conclusion based from the given problem.

15. Let us answer the questions!

16. 1. Do all parts of Earth receive light as it rotate on its axis? Why? No. The “fixed” tilt means that, during our orbit around our Sun each year,  different parts of Earth receive sunlight for different lengths of time . It also means that the angle at which sunlight strikes different parts of Earth's surface changes through the year.

17. 2. What is the effect of Earth’s rotation? The spinning of the Earth  causes day to turn to night

18. 3. What have you noticed about the amount of light received by Earth as it revolves around the sun? As the earth revolves around the sun, the place where light shines the brightest changes. This motion gives us the different seasons. For instance, the poles receive less light than does the equator because of the angle that the land around the poles receive the sun's light.

19. 4. What do you think are the occurrences when Earth revolves around the sun? The Earth is constantly in motion, revolving around the Sun and rotating on its axis. These motions account for many of the phenomenon we see as normal occurrences:  night and day, changing of the seasons, and different climates in different regions .

20. Rotation- is the movement of earth on its axis. Earth roates from west to east. It is clockwise as seen above the North Pole and Counter Clockwise as seen above South Pole. The period of one complete rotation is defined as a day and takes 23 hours, 56 minutes, and 4.2 seconds. Earth’s rotation is inclined or tilted 23.5 degrees relative to its plane of revolution around the sub. The sun, moon, planets, and stars do not orbit around Earth everyday. It appears that the way to us because we observe the sky from a planet that rorates once every day, or 15 degrees per hour.

21. Results from Earth’s Rotation The occurrence of day and night . Places facing the sun experience daytime while those facing away from the sun experience nighttime. The length of daytime and nighttime varies as Earth revolves around the sun.

22. Results from Earth’s Rotation The daily rising and setting of the sun, stars and the moon are the pattern of motion visible in the sky. The sun rises in the east and sets in the west, as do the moon, planets, and the stars. These daily motions are the result from the earth’s rotation.

23. Results from Earth’s Rotation Earth’s rotation affects the flow of air and water on earth. Flowing air and water are diverted from north-south direction to an east-west direction because of Earth’s rotation. The diversion of direction is called the Coriolis effect.

24. Revolution is the movement of an object around the bigger object. Earth revolves around the sun. Its orbit around the sun is in the form of a slightly flattened cirle called an ellipse. The sun is hot at the center of the orbit, but is slightly off to one side. This explains why Earth’s distance from the sun varies. It is closest to the sun at 147 million kilometers when it is in its orbit’s perihelion. It is farthest from the sun at 152 million kilometers when it is in its orbit’s aphelion.  

25. Earth revolves around the sun as it roates , or spins, on its axis. The period of one revolution around the sun is defined as a year. One complete revolution of earth is 365.24 solar days or 365 days, 5 hours, 48 minutes, and 46 seconds. Earth’s axis is tilted. As it orbits the sun, Earth’s axis remains fixed in space so that at one poinr , the northern hemisphere of earth is tilted.    

26. Results from Earth’s Revolution   Occurrence of Seasonal Changes The seasons change through the year; the length of days varies; and the temperature may range from cold to hot depending on the latitude where you live. The annual changes are the result of Earth’s orbital motion around the sun is called a revolution. Our seasons are created by this orbit tilt and by Earth’s orbital motion around the sun.
