4. Olivia Wilson Claudia Alves Aaron Loeb LEARNING OBJECTIVES By the end of today’s session, we will be able to: Analyze how the rotation of Earth causes to experience day and night . Analyze how the revolution of Earth causes to experience seasons .

5. Key Words: ROTATION REVOLUTION ORBIT Date: ______________________ ACTIVITY BOOK B PAGE:7.1 2-5 BIG TASK : You are an astronaut who often goes to space for scientific investigations. Your younger sibling in Grade 2 wonders how day and night come about, and why seasons keep on changing every year. Using your knowledge as an astronaut, create a model that demonstrates both the revolution and rotation of the Earth to explain to him about rotation and revolution. Activity book B page 2-3 To create your model, you have to do the following: Place a sticker on the ball. 1.Turn off the light. One person holds the ball and another person holds he flashlight 2.Slowly rotate the ball and watch the sicker as it completes one rotation. 3.Draw 2 diagrams to show the position of the sticker when it is pointing the flashlight and when it’s pointing away from the flashlight. (15 mins .)

6. SUCCESS CRITERIA 1. . Define rotation and revolution 2. Explain why we experience alteration of day and night 3. Analyze and interpret how Earth’s revolution causes to experience seasons. I will… What will I do to achieve the task?

7. The earth spins on its_____________. It completes one ______________ in 24 hours. The axis is an imaginary__________ through the earth’s center Fill in the blanks to complete the statement. Use the word bank below. rotation axis Rotation line axis line

8. The earth moves on a curved path called_________ around the sun. It takes the earth 365 days to complete one ______ of the sun. Fill in the blanks to complete the statement. Use the word bank below. revolution orbits orbits Revolution

9. ACT IVITY 1: Video Analysis Explain how the rotation of the Earth causes us to experience day and night Link: https ://youtu.be/MtRzy2TJAOQ?si=7-GIZom5LcfMbfL3

10. The spinning movement of Earth on its axis ROTATION It takes the Earth 24 hours to complete one rotation.

11. Part of Earth facing the Sun is in DAY-TIME . Part of Earth facing away the Sun is in NIGHT-TIME .

12. Role play/simulation Group Task: simulate the rotation of the earth in front of the class . Instructions: In groups(partner) choose one person to play the part of: Sun 2. Earth . Apply creativity in your presentation.

13. ACT IVITY 2 : Video analysis Task: 1. Analyze and interpret how Earth’s revolution causes to experience seasons . Link: https://youtu.be/6SzjlsuyTdk?si=PPuAoI8eHuAShOjs

14. The movement of Earth in a curved path ( orbit ) around the Sun . REVOLUTION It takes the Earth 365 days to complete one revolution.

15. COMPARE - Differentiate between Rotation and Revolution

16. One day on Jupiter is just 10 Earth hours. One day on Venus is 243 Earth days. Why is the length of a day on each planet is different ? LINK TO LIFE: VALUE OF THE MONTH: FEBRUARY INTEGRITY AND TRUST

19. Activity 7.1 – pages 4,5 The light stays in place as the basketball moves from light to dark. It changes from day to night.

20. SUCCESS CRITERIA 1. . Define rotation and revolution 2. Explain why we experience alteration of day and night 3. Analyze and interpret how Earth’s revolution causes to experience seasons. I can What will I do to achieve the task?

21. PLENARY - Let’s act out the movement of the Earth around the Sun to wrap up our lesson.

22. Let’s Wrap-Up! PLENARY: What have you learned about the lesson today? Example: Today, I learned that…
