6 What I Need to Know At the end of this module, learners are expected to: 1. The learners shall be able to recognize the uniqueness of Earth, being the only planet in the solar system with properties necessary to support life. (S11/12ES-Ia-e-3) 1.1 Recognize the difference in the physical and chemical properties between the Earth and its neighboring planet 1.2 Identify the factors that allow a planet to support life 1.3Appreciate the uniqueness of earth being the only planet in the solar system that has properties to support life. 2. The learners shall be able to understand the Earth consists of four subsystems, across whose boundaries matter and energy flow. (S11ES-Ib-4) 2.1 Define the concept of a system; and 2.2 Recognize the Earth as a system composed of subsystems. 2.3 Appreciate the things around us that makes earth’s system
7 What I Know Observe the picture of ecosystem below; write down all the images that you see every day in your life. 1. ___________________ 2. ___________________ 3. ___________________ 4. ___________________ 5. ___________________ Look outside your window and see what’s in the image that is present around you. Does the sky look the same? The sun brightly shines or a gloomy weather that it’s like going to rain? Trees and plants that give fresh air, rivers that give fresh environment. Do you sometime stop and think everything? around you connectively has something to do with each other?
8 Lesson 1 Recognize the uniqueness of Earth, being the only planet in the solar system with properties necessary to support life. To enable life, Planet Earth has a number of ideal features. It is unique among planets in our solar system for having water in its liquid form in an amount conducive to evolution of life, The Atmosphere trap certain amount of heat from the sun to warm the earth, the main heat source comes from the sun. In this module you will learn Earth’s unique characteristics among other planets in the solar system that sustain life. To understand deeper, properties in our planet are interconnected and interact to one another to form a unified whole and process a cycle where matter and energy flow. That’s how amazing our planet earth revolves around us.
9 Notes to the Teacher This module will help the student to know the Earth What’s In Compare and Contrast. Write down on a piece of paper what are the similarities and differences among these three terrestrial planets? Venus Earth Mars 1. Venus, Earth, and Mars are part of the inner terrestrial or "rocky" planets. Their composition and densities are not too different from each other. 2. Venus is considered to be the Earth's twin planet. It has a very similar size and mass with the Earth. Mars is about half the Earth's size. 3. Orbital period and velocity are related to the planet's distance from the sun. Among the three planet, Venus is the nearest and Mars is the farthest from the Sun. 4. Rotational speed of Earth and Mars are very similar. Rotational speed of Venus is extremely slow. 5. Abundance of liquid water is only observed on Earth, hence the blue color.
10 What’s New Analysis of Theories, Concepts and Principles What factors would make a planet habitable? Observe the earth’s characteristics that it become unique and habitable. Factors that make a Planet Habitable Functions Right Factors Temperature Influences how quickly atoms & molecules move Life seems limited to a temperature range of minus 15 °C to 115°C. In this range, liquid water can still exist under certain conditions Water Dissolves & transports substance within and to and from a cell Water is regularly available. Life can go dominant between wet periods. Atmosphere Traps heat, shields the surface from harmful radiation, and provides chemicals needed for life, such as nitrogen and carbon dioxide. Earth & Venus are the right size to hold a sufficient-sized atmosphere. Earth’s atmosphere is about 100 miles thick. It keeps the surface warm & protects it from radiation & small- to medium-sized meteorites Energy Organisms use light or chemical energy to run their life processes. With a steady input of either light or chemical energy, cells can run the chemical reactions necessary for life.
11 Nutrients Used to build and maintain an organism’s body. All solid planets & moons have the same general chemical makeup, so nutrients are present. Those with a water cycle or volcanic activity can transport and replenish the chemicals required by living organisms. Earth has a complex system compose of four subsystem- geosphere, hydrosphere, atmosphere and biosphere that interact to carry out many differential natural processes (physical, chemical, biological). Components or Earth’s subsystem The arrows in the diagram indicate the interaction among the components SOLAR ENERGY Lithosphere Atmosphere Biosphere Hydrosphere
12 What is It Earth is the only planet in the solar system that it is known to have life on it, no other planet in the solar system to have life on them. The processes that shape the Earth and its environment are through constant cycle. This cycling sustains life and leads to the formation of the mineral and resources that are the foundation of modern technological society. Sun, as the main source of heat by solar radiation our planet receives. Our earth is protected by the atmosphere 100 miles thick. It kept the surface warm by insulating the atmosphere & protects it from radiation & small- to medium-sized meteorites, and it has the right chemical properties for life, including water and carbon. According to the National Geographic (www.nationalgeographic.com) A NASA scientist list 5 essential ingredients needed to sustain life. There must be temperature, water, sunlight, nitrogen and yes, its oxygen, the evidence of life. Life, in general can tolerate a wide range of temperature conditions. Planets should have sufficient size to hold a significant atmosphere, the composition of the atmosphere specifically the amount of greenhouse gases (The concept of greenhouse gases and its interconnectivity will be discuss in the succeeding lesson) influences the earth’s surface temperature. The temperature range that allows water to exist in the liquid state, about 70% of the Earth is covered with liquid water, the liquid form turns out to be one of the most important pre-requisite for life as we know it.
13 On Earth, nutrients are recycled through the hydrologic cycle and plate tectonics (volcanism). The amount of solar radiation that a planet receives is primarily a function of distance from the sun, because sunlight is essential for photosynthesis. A system that will be able to constantly supply nutrients to organisms as it is important to sustain life. Thus, this earth’s unique composition and characteristics present in our planet make the Earth as only planet in the solar system with properties necessary to support and sustain life. Earth is the solely planet in the solar system that it is recognized to have life on it, no other planet has. The processes that shape the Earth and its environment are through constant cycle. This cycling sustains life. To understand deeper take a closer look to two pictures below, how subsystem interact to one another. Fig. 1 Fig. 2 Do you remember the concept of ecosystem? How everything around us interact with each other, the same way with the earth subsystem, during summer or hot weather season what have experience? Do you sometimes feel it’s too much hot that you think it’s not normal at all? Exactly what the figure shown is the El Nińo Phenomenon (e.g. hot and dry, no rain, water crisis) It is the result of the hydrosphere (ocean)-atmosphere interaction and the biological (Biosphere) response to it is the decrease of fish catch in the ocean. The subsystems of the
14 Earth (atmosphere, hydrosphere, biosphere, and lithosphere) interact with each other. Earth system is essentially a closed system. It receives energy from the sun and returns some of this energy to space. The atmosphere is the thin gaseous layer that envelopes the lithosphere. The lithosphere includes the rocks of the crust and mantle, the metallic liquid outer core and the solid metallic inner core. About 70% of the Earth is covered with liquid water (hydrosphere) and much of it is in the form of ocean water. The biosphere is the set of all life forms on Earth. A closed system is a system in which there is an exchange of heat or energy, Warm air converges and rises to form low pressure zones, cold air descends to form high pressure regions. The carbon cycle is the process by which carbon is transferred among the atmosphere, oceans, soil, and living organisms. The water cycle in your grade 8 class, the process of weathering and erosion (natural and man-made), and the hydrologic cycle is another important process contributing to the shaping and reshaping of the surface of the Earth. This is an important link among the biosphere, hydrosphere, atmosphere, and lithosphere.

    8 Lesson 1 Recognize the uniquenessof Earth, being the only planet in the solar system with properties necessary to support life. To enable life, Planet Earth has a number of ideal features. It is unique among planets in our solar system for having water in its liquid form in an amount conducive to evolution of life, The Atmosphere trap certain amount of heat from the sun to warm the earth, the main heat source comes from the sun. In this module you will learn Earth’s unique characteristics among other planets in the solar system that sustain life. To understand deeper, properties in our planet are interconnected and interact to one another to form a unified whole and process a cycle where matter and energy flow. That’s how amazing our planet earth revolves around us.

    9 Notes to theTeacher This module will help the student to know the Earth What’s In Compare and Contrast. Write down on a piece of paper what are the similarities and differences among these three terrestrial planets? Venus Earth Mars 1. Venus, Earth, and Mars are part of the inner terrestrial or "rocky" planets. Their composition and densities are not too different from each other. 2. Venus is considered to be the Earth's twin planet. It has a very similar size and mass with the Earth. Mars is about half the Earth's size. 3. Orbital period and velocity are related to the planet's distance from the sun. Among the three planet, Venus is the nearest and Mars is the farthest from the Sun. 4. Rotational speed of Earth and Mars are very similar. Rotational speed of Venus is extremely slow. 5. Abundance of liquid water is only observed on Earth, hence the blue color.

    10 What’s New Analysis ofTheories, Concepts and Principles What factors would make a planet habitable? Observe the earth’s characteristics that it become unique and habitable. Factors that make a Planet Habitable Functions Right Factors Temperature Influences how quickly atoms & molecules move Life seems limited to a temperature range of minus 15 °C to 115°C. In this range, liquid water can still exist under certain conditions Water Dissolves & transports substance within and to and from a cell Water is regularly available. Life can go dominant between wet periods. Atmosphere Traps heat, shields the surface from harmful radiation, and provides chemicals needed for life, such as nitrogen and carbon dioxide. Earth & Venus are the right size to hold a sufficient-sized atmosphere. Earth’s atmosphere is about 100 miles thick. It keeps the surface warm & protects it from radiation & small- to medium-sized meteorites Energy Organisms use light or chemical energy to run their life processes. With a steady input of either light or chemical energy, cells can run the chemical reactions necessary for life.

    11 Nutrients Used tobuild and maintain an organism’s body. All solid planets & moons have the same general chemical makeup, so nutrients are present. Those with a water cycle or volcanic activity can transport and replenish the chemicals required by living organisms. Earth has a complex system compose of four subsystem- geosphere, hydrosphere, atmosphere and biosphere that interact to carry out many differential natural processes (physical, chemical, biological). Components or Earth’s subsystem The arrows in the diagram indicate the interaction among the components SOLAR ENERGY Lithosphere Atmosphere Biosphere Hydrosphere

    12 What is It Earthis the only planet in the solar system that it is known to have life on it, no other planet in the solar system to have life on them. The processes that shape the Earth and its environment are through constant cycle. This cycling sustains life and leads to the formation of the mineral and resources that are the foundation of modern technological society. Sun, as the main source of heat by solar radiation our planet receives. Our earth is protected by the atmosphere 100 miles thick. It kept the surface warm by insulating the atmosphere & protects it from radiation & small- to medium-sized meteorites, and it has the right chemical properties for life, including water and carbon. According to the National Geographic (www.nationalgeographic.com) A NASA scientist list 5 essential ingredients needed to sustain life. There must be temperature, water, sunlight, nitrogen and yes, its oxygen, the evidence of life. Life, in general can tolerate a wide range of temperature conditions. Planets should have sufficient size to hold a significant atmosphere, the composition of the atmosphere specifically the amount of greenhouse gases (The concept of greenhouse gases and its interconnectivity will be discuss in the succeeding lesson) influences the earth’s surface temperature. The temperature range that allows water to exist in the liquid state, about 70% of the Earth is covered with liquid water, the liquid form turns out to be one of the most important pre-requisite for life as we know it.
  • 15.
    13 On Earth, nutrientsare recycled through the hydrologic cycle and plate tectonics (volcanism). The amount of solar radiation that a planet receives is primarily a function of distance from the sun, because sunlight is essential for photosynthesis. A system that will be able to constantly supply nutrients to organisms as it is important to sustain life. Thus, this earth’s unique composition and characteristics present in our planet make the Earth as only planet in the solar system with properties necessary to support and sustain life. Earth is the solely planet in the solar system that it is recognized to have life on it, no other planet has. The processes that shape the Earth and its environment are through constant cycle. This cycling sustains life. To understand deeper take a closer look to two pictures below, how subsystem interact to one another. Fig. 1 Fig. 2 Do you remember the concept of ecosystem? How everything around us interact with each other, the same way with the earth subsystem, during summer or hot weather season what have experience? Do you sometimes feel it’s too much hot that you think it’s not normal at all? Exactly what the figure shown is the El Nińo Phenomenon (e.g. hot and dry, no rain, water crisis) It is the result of the hydrosphere (ocean)-atmosphere interaction and the biological (Biosphere) response to it is the decrease of fish catch in the ocean. The subsystems of the
  • 16.
    14 Earth (atmosphere, hydrosphere,biosphere, and lithosphere) interact with each other. Earth system is essentially a closed system. It receives energy from the sun and returns some of this energy to space. The atmosphere is the thin gaseous layer that envelopes the lithosphere. The lithosphere includes the rocks of the crust and mantle, the metallic liquid outer core and the solid metallic inner core. About 70% of the Earth is covered with liquid water (hydrosphere) and much of it is in the form of ocean water. The biosphere is the set of all life forms on Earth. A closed system is a system in which there is an exchange of heat or energy, Warm air converges and rises to form low pressure zones, cold air descends to form high pressure regions. The carbon cycle is the process by which carbon is transferred among the atmosphere, oceans, soil, and living organisms. The water cycle in your grade 8 class, the process of weathering and erosion (natural and man-made), and the hydrologic cycle is another important process contributing to the shaping and reshaping of the surface of the Earth. This is an important link among the biosphere, hydrosphere, atmosphere, and lithosphere.
