Solar System Lesson Our Place in the Solar System1 Overview: It is very important for Students to have a full understanding of where earth is in our solar system, how relatively large it is and how relatively small it is. It is also important for students to understand that the earth rotates around the sun and the earth is itself rotating all the time. Also it is important to have somewhat of an understanding of each of the other planets of our solar system. The knowledge of these things will be exercised through an online discussion via a Chatterous group chat. This group will provide students with instant feedback from both the instructor and their peers. Objectives Materials 1 In this activity students should learn what planetary days and years are. They will also learn about the earth’s size, and distance from the sun. For students to gain the knowledge and tools required to create a chatterous group, and discuss classroom materials within the chatterous group 8-14 sports balls of various sizes (from a ball bearing to a basketball) for use as representation of different planets in a scale setting. Large room, or outdoor sports field (optional smaller model for use on table top. Access to a computer for use of the Chatterous web group preferred home internet access for ‘homework’ version of the second part of the assignment. Information adapted from http://www.noao.edu/education/peppercorn/pcmain.html Solar System Lesson Procedures 1. Before beginning the activity the students should have some knowledge of each of the eight planets, and the existence of the dwarf planets 2. Students will also join a pre-created group on the Chat website ‘Chatterous’ to discuss the major differences between their planet, and those of their classmates 3. The students will collectively form a scale model of the solar system Students will each be given an individual Spherical object in representation of a scale planet. 4. For the graded portion of this project the students will all join the Chatterous group at a specified time, and discuss with each other and the instructor a few characteristics of their planet. The length of a day The length of a year How much more or less you would weigh on each planet. How hot or cold the planets are Standards o Indiana State Standard 6.3.1 The Physical Setting. Compare and contrast the size, composition, and surface features of the planets that comprise the solar system, as well as the objects orbiting them. Explain that the planets, except Pluto, move around the sun in nearly circular orbits o Indiana State Standard 6.3.2 Observe and Describe that planets change their position relative to the background of stars. o Indiana State Standard 6.3.3 Explain that the Earth is one of several planets that orbit the sun and that the moon, as well as many satellites and debris, orbit around the Earth.
