A scientist is a person who studies or has expertise in science. A scientist tries to understand how our world, or other things, work. Scientists make observations, ask questions and do extensive research work in finding the answers to many questions others may not know about.

Scientists may work in laboratories for governments, companies, schools and research institutes. Some scientists teach at universities and other places and train people to become scientists. Scientists often make experiments to find out more about reality, and sometimes may repeat experiments or use control groups. Scientists who are doing applied science try to use scientific knowledge to improve the world.

Types of scientists

Scientists can work in different areas of science. Here are some examples:

A scientist is someone who believes that there is a natural explanation for most things. For any problem they see, scientists try to understand the cause so they can come up with a solution. By learning what causes a disease, for example, scientists can work to control its spread.

Science is a very wide field of study. Scientists usually focus on one branch of science. They may study plants ( botany), the universe ( astronomy), matter ( physics), or animals ( zoology). Engineers, doctors, veterinarians, geologists, archaeologists, and ecologists are all scientists as well. (For a list of famous scientists, see scientists at a glance.)

Scientists must go to college to earn a degree in their chosen scientific field. After earning a bachelor's degree, some scientists, such as engineers, may enter the workforce. However, other scientists, such as doctors, need to earn higher degrees in order to practice. Some scientists become teachers after they earn their degrees. They may stay at a university. They can do research and write about their discoveries while they continue to teach others. Other scientists may work for companies that want to develop new products. Some scientists work in laboratories while others work outside, doing things like digging up dinosaur bones or collecting plants.
