Earth History Unit Time required for unit: Four Weeks Title of the Unit: Origin of the Universe and Solar System Purpose: For students to gain an understanding of the types of objects in the universe, including galaxies, stars and planets, with focus on our own solar system. Students will develop and understanding of the theory of the origin of our solar system and the origin of our planet Earth. Big Ideas: The scale of the universe and our solar system: size, age, and distance between objects. The origin and organization of the solar system Accretion Gravity Density Unique physical characteristics of the main bodies in our solar system Sun Each of the nine planets The Earth’s Moon Connections to the real world: A basic understanding of the history of our solar system and the origin of the Earth is the foundation of a more detailed understanding of the physical characteristics of our planet, Earth. Learning Outcomes: Upon successful completion of this unit, students should be able to: 1. Describe Earth in the context of the rest of the universe. 2. Explain the current theory of the origin of the solar system from a nebular dust and gas cloud to the formation of each planet. 3. Categorize the nine planets as terrestrial or a gaseous and describe basic physical characteristics of each planet type, such as size, mass, and mean density. 4. Use the concept of ratios and unit conversions to create a scale model of the solar system that accurately represents both the size and relative location of each planet within the solar system. 5. Explain the physical characteristics of the Sun and the Moon and their importance to Earth. 6. Identify characteristics unique to Earth and explain why those characteristics are important for the development of life on Earth. Assessment: Students will be assessed on the various tasks throughout the unit. There will be a total of three quizzes on the material covered in the lessons as well as the individual and group activities. There will be continuing checks for understanding throughout the unit, this will allow for any misunderstandings, misconceptions and any unclear topics to be readdressed allowing for clearer understanding by the student. A unit exam will ultimately be given, in this the students will be asked to associate the material learned in the unit with their immediate surroundings, this will test the students’ complete comprehension of the topics and how it affects them directly. There will also be a research project where in students will report on a topic of interest they have chosen and report to the class their findings.
