Exercise A - Measuring distance 1. Obtain a wooden meter stick. If you look on the back of the meter stick, one meter is approximately 39 inches or about 3 inches longer than one yard (36 inches). Using the meter stick, estimate the size of the laboratory by measuring its width and length to the nearest meter. 2. Observe that the meter is divided into 100 equal units called centimeters. A centimeter is about the width of a small finger. Using the meter stick, estimate the dimensions of a regular piece of notebook paper to the nearest centimeter. 3. How tall are you? Go over to the medical weight and height scale to measure how tall you are to the nearest centimeter. 4. Next, obtain a small plastic metric rule. Observe that each centimeter is divided into 10 small units called millimeters. A millimeter is about the thickness of a fingernail. Using the small plastic ruler. estimate the diameter of a hole on a regular piece of notebook paper to the nearest millimeter. In the United States when we travel by car distances are measured in miles For example
