Science 7

1. PARTICLES OF MATTER

2. At the end of the lesson, you shall be able to: infer that particles in matter move farther and faster when they absorb heat. OBJECTIVES 2

3. Classify each statement as Substance or Mixture. Write S if it is a substance, M if mixture, and SM if it is true to both substance and mixture. MIXTURE OR SUBSTANCE? Refer to your worksheet

4. Write a brief description you have done recently because of inspiration. Explain what or who inspired you to take that action. SHARE US YOUR EXPERIENCE

5. BEHAVIOR What they shared about their actions and what motivated them are examples of behavior. Behavior is how we act or react in response to something, just like how you were inspired to do those things.

6. BEHAVIOR Their stories show how powerful inspiration can be. Now, imagine if even the smallest building blocks of matter, like atoms and molecules, have their own behaviors. What do you think might inspire their actions?

7. INVESTIGATE Let’s investigate the behaviors of particles of matter and find out what inspires them.

8. BUT, REMEMBER THESE WORDS FIRST! Matter- refers to any object big or small. Random- refers to motion in different directions Behavior- is an action due to a certain cause Vapor- refers to gas Compound- is a substance composed of different kinds of particles

9. Important Matters Matter is composed of particles. These particles are in constant random motion. Particles in liquids and gases move from one place to another in an object while particles in solids vibrate from their position. TIME TO READ! Refer to your worksheet

10. When particles absorb heat, they become ‘excited or inspired’ such that they move faster and farther. As they move faster and farther, the size of the object increases. The increase in size due to absorption of heat is called Thermal Expansion. Different objects expand in different amounts.

11. WANT TO KNOW BOARD I will be giving you a paper strip, identify one idea from the material you have read that you want to know more. Please post it on the Want To Know Board. I have prepared it here on the board.

12. TIME TO GET TO THE CORE OF THE MATTER You will be doing two activities, one each in the learning stations that I prepared ( 3 identical set-ups). Observe safety – no playful activities!

13. INVESTIGATION TIME! Refer to your worksheet Answer the guide questions and present in class afterwards

14. LET’S DISCUSS YOUR ANSWERS! Group presentation 1 representative from each group will discuss the answers

15. HOW DEEP IS YOUR UNDERSTANDING ? To deepen your understanding, explain the following situations:

16. In Station A, what would have happened to the colored water if the water in the beaker was hot? Question

17. Why is it not advisable to fill to the brim a kettle when boiling water? Question

18. Why is a normal person able to smell the perfume of another person located at the end of a room? Question

19. If the monggo seeds were bigger, would they reach the same distance and speed? Question

20. What then affects the distance and speed of the particles? Question

21. 1. Particles of object move _____. Particles in solid _____ in their position while vapor and liquid particles ________________. 2.Particles move _____________ when heated. In effect, the volume of matter _______. 3.Thermal expansion occurs when materials are _____ while Thermal Contraction occurs when _______. CAN YOU SUMMARIZE? Com plete the following statements .

22. QUIZ TIME Let's put your knowledge to the test!

23. DIRECTIONS Read the questions carefully and choose the letter of the correct answer. Write your answer in a separate piece of paper or in the worksheet provided by your teacher.
