LESSON 2: EARTH & EARTH SYSTEMS (EARTH & LIFE SCIENCE)

This is a teacher-made power point presentation for Lesson 2 in Earth and Life Science.
Learning Competency: Explain that the Earth consists of four subsystems, across whose boundaries matter and energy flow.

1. EARTH AND EARTH SYSTE MS DISCUSSANT : JOHN MARK P. MATAMOROSA

2. CLASS RULES : RULE 1 Listen quietly when others are speaking. RULE 2 Raise your hand for permission to get up or speak. RULE 3 Collaborate with others during group activities. RULE 4 Always treat others with respect. RULE 5 Believe in yourself.

3. At the end of 60-minute interactive discussion, all of the students are expected to: identifies Earth’s sub-systems; explain how the Earth subsystems are interacting with each other to support life on Earth; and show appreciation to the wonder of our home planet Earth. LE ARNING OBJECTIVES:

18. WA TCH ! Four Subsystems of the Earth Guide Questions: What are the four subsystems of the Earth? What is atmosphere? What is hydrosphere? What is geosphere? What is biosphere?

19. ROLE PLAY! H ow to preserve the beauty and the role of subsystems on Earth Rubrics: Presentation- 50% Understanding of Topic- 30% Cooperation- 20%

20. First Sub-system: Atmosphere The word atmosphere comes from the Greek roots atmos which means gas, and sphaira which means globe or ball. The atmosphere makes up all the gases on Earth. It extends outward about 10,000 km from the surface of the Earth.

21. Second Subsystem: Geosphere The geosphere is considered that portion of the Earth system that includes the Earth’s interior, rocks and minerals, landforms and the processes that shape the Earth’s surface. The Earth itself is not a perfect sphere but an oblate spheroid, with a radius of 357 kilometers (km) from the Earth’s center to the North Pole and 378km from the center of the Equator.

22. Third Subsystem: Hydrosphere The hydrosphere is the sum of all water on Earth and the water cycle that distributes it around the planet. Earth is unique in the solar system for its abundant surface waters. Our orbital distance from the sun, in addition to our unique atmosphere, gives Earth the right temperature in our middle-aged solar systems to have water as a liquid, and lots of it. It’s because of the hydrosphere that life flourishes on Earth.

23. Fourth Subsystems: Biosphere Biosphere contains the entirety of Earth’s living things. It is sometimes referred as the “zone of life.” From a geophysical standpoint, biosphere is the global ecological system integrating all living things and their relationship including their interactions with the elements of the lithosphere, hydrosphere and atmosphere. The biosphere is divided into biomes. Biomes are the world’s major communities. They are classified according to the predominant vegetation characterized by adaptations of organisms to that particular climate.

24. D irection : From the given situations, choose two BEST earth systems that are interacting (geosphere, biosphere, hydrosphere, atmosphere. A CTIVITY TIME! 1. The mango tree in your backyard is blown by the wind. 2. Your classmate Pedro gets caught in the rain. 3. Typhoon Tisoy damages sugar cane crop in the Bicol Region. 4. Air next to the ground becomes warm. 5. Water vapor condenses .

25. QUIZ TIME! 1. Choose from the following spheres or subsystems where SOIL is found. A. Hydrosphere B. Biosphere C. Geosphere D. Atmosphere

26. QUIZ TIME! 2. Ocean is found in __________. A. Geosphere B. Biosphere C. Atmosphere D. Hydrosphere

27. QUIZ TIME! 3. ROCKS, MINERALS and LANDFORMS are part of ____________. A. Biosphere B. Hydrosphere C. Atmosphere D. Geosphere

28. QUIZ TIME! 4. In which sphere does HUMAN BEING could be found? A. Biosphere B. Atmosphere C. Geosphere D. Hydrosphere

29. QUIZ TIME! 5. Oxygen is part of __________. A. Atmosphere B. Biosphere C. Geosphere D. Hydrosphere

30. QUIZ TIME! 6. Which subsystems below does LAKE belongs to? A. Atmosphere B. Biosphere C. Hydrosphere D. Geosphere

31. QUIZ TIME! 7. MICROBES are part of __________________. A. Geosphere B. Biosphere C. Hydrosphere D. Atmosphere

32. QUIZ TIME! 8. In what subsystem does sand belongs to? A. Geosphere B. Hydrosphere C. Biosphere D. Atmosphere

33. QUIZ TIME! 9. INSECTS is also a part of _______________ because it contains all living things. A. Biosphere B. Atmosphere C. Hydrosphere D. Geosphere

34. QUIZ TIME! 10. In ____________, carbon dioxide can also be found. A. Hydrosphere B. Atmosphere C. Biosphere D. Geosphere

35. KEY TO CORRECTION 1. C 2. D 3. D 4. A 5. A 6. C 7. B 8. A 9. A 10. B

36. ASSIGNMENT A. Direction: Construct an essay about this question. How does the 4 subsystems work together to support life on earth?

37. ASSIGNMENT B. Direction: In your own words, explain in 3-5 sentences how the reflected subsystems are interacting. Write your answer in your quiz notebook. 1. Water is necessary for the transport of nutrients and waste products in organisms like plants, animals, and human. 2. Typhoon forms when there is an LPA which intensify as it absorbs the water vapor in the Pacific Ocean which in turn causes landslide and destruction of organisms. 3. Global warming heats up the Pacific Ocean causing the glaciers to melt and adding more water to the ocean.
