If you like numbers, science can be for you too, since scientists make many measurements. Things like length, weight, time, and volume are measured frequently. Movie heroes like Indiana Jones live lives of high adventure. Scientists experience adventure too, especially when new information is discovered which might explain how something works, or even help cure people of a killing disease. The scientists and their teams who made these discoveries sense excitement, adventure, and satisfaction because they are understanding how something works for the first time, and maybe solving a serious problem too.
Some scientists specialize in studying living things.
We call them biologists. Some try to learn more about the ground and the earth. They're called geologists. Physicists are scientists who study physical phenomena such as light or electricity. At the National Institute of Environmental Health Sciences in the Research Triangle Park in North Carolina, dozens of dedicated toxicologists study the effects of different chemicals on living things.
