Vocabulary: base unit, cancel, conversion factor, dimensional analysis, metric system, prefix, scientific notation Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Sara lives in Toronto, Canada, while her cousin Michael lives in Detroit, Michigan. They like to compare how fast they are growing up. 1. Sara tells Michael she is 160 centimeters tall, while Michael says he is 60 inches tall. 2. Michael tells Sara he weighs 104 pounds. Sara says she is 44 kilograms. Gizmo Warm-up As you could see from the questions above, there are different ways to measure the same quantity. Every measurement includes both a number and a unit. There are many, many different units you can use to measure the same attribute, such as height, weight, or volume. The Unit Conversions Gizmo shows you how you can convert from one unit to another in order to compare measurements. 1. To begin, check that this question is shown: The tallest building in the world, the Burj Khalifa in Dubai, is 0.828 kilometers high. What is the building’s height in centimeters? (If this is not the question you see, click Next until it appears.) 2. Look for the Unit Conversion Tile that has the unit “meter” on top and “kilometer” on the bottom. This tile shows a conversion factor, or a ratio that compares two equivalent values. Reproduction for educational use only.
