What is science? Well, by asking that question, you already have one foot in the door to understanding. That’s because, at its most basic level, science is about asking questions to better understand the world around you. It is the systematic study, testing, and asking questions to know the universe. Science is divided into three major branches: natural sciences, which study nature; social sciences, which study people; and formal sciences, like mathematics, which study logic. There are also applied sciences, such as medicine and engineering, that use science to do specific tasks.


Agriculture science involves feeding the world. This field has been around since the beginning of civilization, but progress and discoveries around cultivating food and textiles are occurring today. If you're interested in plants, crop production, or livestock, consider agricultural science.

Sample Careers: Food Scientist, Farmers

STEM Outlook: Depending on the type of agricultural science career, the U.S. Bureau of Labor Statistics estimates job growth to be moderate or slower than normal over the next decade.

It's all about the animals in this area of science. Whether large or small, animals have a great impact on our ecosystems and society. The study of animal science helps us understand and manage domestic animals and wildlife. Some areas of animal science include wildlife management, food production, veterinary medicine, conservation biology, and zoology.

Sample Careers: Veterinarian, Zoologist

STEM Outlook: The U.S. Bureau of Labor Statistics estimates jobs in this field will grow slightly faster than average over the next decade.

Environmental science is an interdisciplinary field that integrates areas of life, physical, and earth science to study and address problems facing the environment. Careers in this field implement science-based solutions to problems facing our environment and ecosystems.

Sample Careers: Hydrologist, Environmental Lawyer

STEM Outlook: Envionmental scientists have a projected career growth of 8 percent over the next decade, according to the U.S. Bureau of Labor Statistics.

Chemistry is a branch of natural science that deals principally with the properties of substances, elements, molecules, and atoms. Chemistry studies the changes these substances undergo, and the natural laws that describe these changes. Chemicals are everywhere! Anything you can touch, smell, or see contains one or more chemicals. Many occur naturally, but some are man-made. Because chemicals are everywhere, chemistry is one of the foundations of modern industrial economies.

Physics uses the laws of nature to predict behavior of motion, matter and energy. Many of the everyday technological inventions that we now take for granted resulted from discoveries in physics. The basic laws in physics are universal, but today there are many sub-fields, including quantum mechanics, thermodynamic physics, and electromagnetism.

Sample Careers: Physicist

STEM Outlook: Over the next decade, the demand for physicists will grow 7 percent, or faster than average, according to the U.S. Bureau of Labor Statistics.

In STEM, astronomy is a science that seeks to explain everything that we observe in the universe, from the comets and planets in our own solar system to distant galaxies to the echoes of the Big Bang. By studying the cosmos beyond our own planet, we can understand where we came from, where we are going, and how physics works under conditions which are impossible to recreate on Earth.

Sample Careers: Astronomer

STEM Outlook: In the field of astronomy you can pursue a career as an university faculty or researchers, observatories, and government labs, with about 10 percent working in private industry or at planetariums or museums.
