Teacher Background Information
The study of the human body can be a very enlightening and, thereby, a veryrewarding experience for a young child. Although all of us believe we are familiar with our individual bodies, we may also feel that they are mysterious. As we look at ourselves in the mirror we see some of our body parts, but we know that there are other parts or organs that we cannot see, even as they function. We learn to manage many of the body’s functions at a conscious level — such as throughmovement and thought. However, there are other functions that our bodies perform unconsciously. These unconscious actions such as the beating of our hearts, respiration and digestion are generally not observable. Young children have a natural curiosity about their bodies. This curiosity can motivate them to learn about the human body. Students will find it interesting to measure body temperaturewith a thermometer, especially if they develop some notion for the basis of its use. The basic principle in its operation is that matter usually expands as it absorbs heat. Thermometers contain a substance that readily expands when heated. Mercury, in its liquid state, and alcohol are substances that expand as they absorb heat. Since mercury is more expensive than alcohol, most inexpensivethermometers contain colored alcohol to give the temperature reading. A thermometer scale for the ambient temperature is marked in units called degrees (˚), shown in multiples of 10. The reference points of a thermometer are

usually the freezing and boiling points of water. To measure body temperature, however, oral thermometers show scales between 92˚ and 105˚ F. Each...
