Understanding scale

• Power of Ten

Each student in the class will be assigned one or more of the items in table 8.5. In the upper left corner of a standard 8.5”´11” sheet of paper, write in bold type the approximate dimension of your object in scientific notation. For example, if you are assigned the Earth, you will write 10⁸ m. In the upper right corner, identify the object (e.g. the Earth). In the center of the sheet, place a picture of the object. Internet-based image search engines [sciencesourcebook.com, google.com] may be useful in acquiring pictures that can be copied or drawn. Below the image, give a brief description of the object. As a class, arrange the photographs around the room from smallest to largest as shown in figure 8.5. (Sourcebook for Teaching Science Activity 8.2)
