3. THINK, SOLVE, AND SHOUT Direction: With your group, think on how you will solve the puzzle and shout the word being formed and define it briefly. *the number correspond each letter in the alphabet

4. Guide Questions: 1. How do you find the activity? 2. What are your strategies in order to solve the puzzle?

5. Guide Questions: 1. What is the video all about? 2. What are the different materials found on Earth? 3. What are the four major subsystems of the Earth? How the four subsystem working together in order to sustain life?

6. THE EARTH’S SUBSYSTEM

7. OBJECTIVES at the end of the lesson, the students should be able to: identify the different subsystems of the earth; determine the characteristics of the each subsystem; and explain the importance of studying the different subsystems of the earth

8. SYSTEM a set of interconnected components that are interacting to form a unified whole. The Earth contains four systems: The lithosphere The hydrosphere The atmosphere The biosphere

9. THE ATMOSPHERE The atmosphere is made up of layers of gases that surround the earth. These layers provide living things with air to breathe, trap heat to warm earth and create a protective layer from the Sun. - the present atmosphere is composed of 78% nitrogen (N), 21% oxygen (O2), 0.9% argon, and trace amount of other gases.

10. Troposphere LAYERS OF THE ATMOSPHERE Stratosphere Mesosphere Thermosphere Exosphere The final layer stretches into space and houses satellites. The layer in which we live and weather occurs. The ozone is found in this layer protecting us from UV rays The coldest layer which protects us from meteors because they burn up in this layer. This is the hottest layer because it absorbs the sun's radiation. Auroras occur in this layer.

11. THE HYDROSPHERE The hydrosphere is made up of all the water found on, under and above the earth's surface. This water can be found as liquid, vapor or ice and makes up the water cycle on Earth. about 70% of the Earth is covered with liquid water (hydrosphere) and much of it is in the form of ocean water. -only 3% of Earth's water is fresh: two-thirds are in the form of ice, and the remaining one-third is present in streams, lakes, and groundwater.

12. WHERE IS THE HYRDOSPHERE? Anywhere you can find water! Clouds Rivers Ground Water Oceans Glaciers Lakes

13. THE LITHOSPHERE The lithosphere is the outer layer of the Earth, made up of the crust and upper mantle. These layers provide plants with the nutrients needed to grow and contain the different rocks from the rock cycle.

14. ALL ABOUT THE LITHOSPHERE There are two types of lithosphere: The lithosphere is broken into plates and is often known for it's plate tectonics, the movement that causes earthquakes, volcanos and create various landmarks. Continental Lithosphere Oceanic Lithosphere

15. THE BIOSPHERE Biosphere is the set of all life forms on Earth. it covers all ecosystems—from the soil to the rainforest, from mangroves to coral reefs, and from the plankton-rich ocean surface to the deep sea. .

16. THE BIOSPHERE All of the subsystem interact with one another to support life on Earth. 1. Biosphere and Lithosphere 2. Atmosphere and Hydrosphere - Water Cycle

17. THE ORIGIN OF THE SYSTEMS APPROACH TO THE STUDY OF THE EARTH 1. Friedrich Wilhelm Heinrich Alexander von Humboldt considered the universe as one interacting entity 2. The term "biosphere" was popularized by Vladimir Vernadsky (1863-1945) The lithosphere The hydrosphere The atmosphere The biosphere

18. THE ORIGIN OF THE SYSTEMS APPROACH TO THE STUDY OF THE EARTH The lithosphere The hydrosphere The atmosphere The biosphere 3. In the 1970s, the Gaia Hypothesis was jointly developed by James Lovelock, an English scientist/naturalist, and Lynn Margulis, an American microbiologist. Gaia Hypothesis - the biosphere is a self regulating system that is capable of controlling its physical and chemical environment. 4. In 1983, NASA advisory council established the Earth Systems Science Committee chaired by Moustafa Chahine.

19. CONCEPT MAP Each group must create a concept map that will explain on how the lithosphere, hydrosphere, atmosphere, and biosphere are interconnected. Each group will be given 10 minutes to work on their concept map. Each group shall choose a representative to present their output. Materials needed: manila paper, permanent marker

20. SKIT Each group must create a skit related to Earth Subsystems and on how you are going to appreciate the importance of each subsystems to maintain the stability of life on Earth and how you will take good care each of the subsystems. Each group will be given 10 minutes to plan, practice and present the activity. The skit will be evaluated using the provided rubrics.

21. Assignment Essay. Give at least 100 words. Write it in a 1 whole sheet of Yellow Paper. What is the importance of each subsystems to the stability of life on Earth?
