Plants use the sun to undergo photosynthesis, which helps to produce carbon dioxide. The sun is required to maintain life on Earth. The biosphere, from top to bottom, is about 12 kilometers (20 miles).Īll life exists between 500 kilometers (1,640 feet) below the ocean to 6 kilometers (3.75 feet) above the ocean. Scientists predict that the biosphere is about 12,500 meters (41,010 feet) thick. The biosphere is any place where you can find life. The biosphere extends high up into the atmosphere (where you find birds and insects) and low into the ocean’s hydrothermal vents (where you find octopi, crustaceans, and mollusks). The biosphere consists of humans, plants, animals, and microbes/microorganisms. The biosphere overlaps into the hydrosphere, lithosphere, and atmosphere. As the atmosphere developed, new life forms, including plants and animals, emerged. The early life forms that existed in the biosphere included prokaryotes-organisms that used the sun to undergo photosynthesis. Scientists predict the biosphere is about 3.5 million years old. The biosphere is described as the living world. Vernadsky developed the term “biosphere”. “Bio” comes from the Greek word for “life”.Įnglish geologist Eduard Seuss and Russian physicist Vladimir I. Use this as a guide when explaining each worksheet to the students**īiosphere: the regions of the surface, atmosphere, and hydrosphere of the Earth (or analogous parts of other planets) occupied by living organisms (Dictionary Definition). ** Not all of this information is included on the student worksheets. The worksheets should be reviewed in this order: “What is the Biosphere?” “Earth’s Biomes” “Earth’s Ecosystems”. As the teacher presents, the students will fill in the blank spaces on their worksheets. Next, the teacher will hand out the worksheet packet “Earth’s Biosphere” If it is possible, project each page of the “Earth’s Biosphere” worksheet packet onto the board using a projector or put into a PowerPoint document and project. After the video, the teacher should review the worksheet and discuss the video’s content. As the students watch the video, they will fill in the blanks on their worksheet. The teacher will also hand out the video’s accompanying worksheet. The video is about 2 ½ minutes long and discusses the Earth’s biosphere. The teacher will begin the class by showing the video “Biosphere-Video ” (Source: ). How will the learning of this content be facilitated? The biomes and ecosystems that are found on Earth. The characteristics of the Earth’s biosphere. The definition to the terms biosphere, biome, and ecosystem. To reach this lesson’s objective, students need to understand: What is the most important content in this lesson? The teacher could then provide information sheets about the student’s chosen biome** Prior to the start of the lesson, the teacher could have the students choose a biome. If not, allow the students to use encyclopedias or other books. If computers are available for use, allow the students to look up information on the computer. **Students need to have access to information sources. Place the paper bag aside it will be used during the activity**Ĭomputers or Encyclopedias/Books/Information Sheets **Prior to the start of the class, fold up the “Biome Cards” and place them into the paper bag. “Traveling Through a Biome” activity materials: Materials and Free Resources to Download for this Lesson: What do you know about the Earth’s biosphere? How will students prior knowledge be activated? Prepare the Learner: Activating Prior Knowledge. What are some things you find in nature?ĭo you think you can find these things on other planets? Questions that encompasses the objective: The students will be able to explain characteristics of the Earth’s biosphere. The students will be able to define the terms biosphere, biome, and ecosystem. The students will learn about the Earth’s biosphere.
