When you think of all the ways your body can get hurt---falling off a bike, stepping on a nail, being bitten by a crazed dog---the aches and pains that come from sitting at a computer may not seem like much. But more doctors are getting worried about just that. If you sit at a PC the wrong way, the nerves and muscles in your back, neck and arms can get out of line. _ is the study of how people work and how jobs and equipment can be designed so that people are safer and more comfortable in the things they do---whether that's working on a factory assembly line or sitting in front of a computer. The monitor You should not have to tilt your neck up or down to lock at the screen. Your eyes should be level with the top of the screen. How far away should you sit? Reach your arm out so your fingertips just touch the screen. The keyboard It should be directly in front of you. Don't unfold the legs on the bottom of the keyboard so that it tilts up toward you---it should be as flat as possible, or even tilted away from you. You want your wrists "neutral," which means straight, not bent. This puts less strain on your nerves and muscles. Arms should be close to the body. Don't look at your fingers as you type. Use a document holder to hold papers at the same level as the monitor. Keep the mouse on the same level as the keyboard and close by--- so you don't have to reach for it. The chair Your feet shouldn't dangle---the blood will pool in your feet. They should rest flat on the floor, or on phone books, if necessary. Your back needs support. Roll up a towel and stick it there. The Body If you think of your body as a collection of right angles when you sit at a computer, you should be just fine. Your hips should be at a 90-degree angle to your back. That takes the pressure off the spine. And your knees should bend at a 90 degree angle so your feet are flat. How should you place your foot? A) Rest them on a phone book. B) Rest them on the floor. C) They should rest flat. D) They should dangle.

You know that balloons must be kept away from sharp objects. They also needed to be kept away from flames. A fire can weaken the rubber and cause it to break. However, in this experiment you will find out how you can hold a balloon directly in a flame without breaking the balloon. Materials needed: * two round balloons not inflated * several matches * water Inflate one of the balloons and tie it. Place 1/4 cup of water in the other balloon, and then inflate it and tie it. Light a match and hold it under the first balloon. Allow the flame to touch the balloon. What happens? The balloon breaks, perhaps even before the flame touches it. Light another match. Hold it directly under the water in the second balloon. Allow the flame to touch the balloon. What happens to this balloon? It doesn't break. Why does the balloon with no water break in the flame? The flame heats the rubber of both balloons. The rubber of the balloon without water becomes so hot that it becomes too weak to _ the pressure of the air inside the balloon. However, when the balloon with water in it is placed in the flame, the water takes in most of the heat from the flame. Then, the rubber of the balloon doesn't become very hot, it doesn't weaken, and the balloon doesn't break. Water is a particularly good absorber of heat. It takes a lot of heat to change the temperature of water. On the other hand, when water cools, it gives off a great deal of heat. That's why areas near oceans or other large bodies of water don't get as cold in winter as areas at the same latitude further inland. The purpose of the experiment described in the passage is to prove that _ . A) water is a particularly good absorber of heat B) some balloons can be easily broken, while others can't. C) balloons without water are not as strong as those with water inside. D) the temperature is not up to the latitude.
