What Can I Do With a Degree in Natural Science?

What do careers in the medical, engineering, and astronomical field have in common? They all begin with an undergraduate degree in the natural sciences. Concerned with understanding how the world around us works, natural sciences are divided into two distinct branches: life science and physical science.

Life science, or biology, concentrates on the study of living organisms while physical science comprises physics, chemistry, earth science, and astronomy. Students who choose to major in one of the degrees offered by Seaver College’s natural science division are prepared for enriching careers through hands-on education in the classroom, in laboratories, and out in the field. 


Biochemistry is the application of chemistry to living organisms and biological processes at a cellular and molecular level. Biochemists primarily conduct research projects, such as analyzing DNA. They often draft applications for funding and present their findings to fellow scientists. 

Successful biochemists have a clear understanding of the fundamentals of biology and chemistry as well as calculus and physics. While an undergraduate degree in biology or chemistry is sufficient to obtain an entry-level position in the field, a doctorate degree is required to serve as a biochemist that leads research and development projects.


From aerospace to systems engineering, the primary role of an engineer is to innovate. Engineers work in complex systems, software, and in creating all types of products, applying science and math to technical issues. 

With more than 30 types of engineers, a career in engineering can lead you to building skyscrapers, designing machinery, or locating reservoirs of crude oil beneath the earth’s surface. Despite the variety in the types of engineering, the majority of entry-level engineer positions begin with a bachelor’s degree in engineering or mathematics


Concerned with the study of earth and all that inhabit it, geography is the science of space and place. Geographers collect geographic data through maps, photographs, field observations, and satellite images to analyze, modify, and present their findings. 

A career in geography can lead to jobs in global development, environmental conservation and policy, community well-being and empowerment, and urban and regional planning. While a degree in physical, regional, or human geography is sufficient for entry-level positions in the field, advanced degrees are required for research and teaching positions.


With the ultimate goal of helping people lead healthy lives, nutritionists create realistic, sustainable, and unique food plans for  individuals. Nutritionists have the opportunity to work in a variety of settings, including hospitals, senior care facilities, athletic departments, resorts, and private practice. 

Besides having a passion for food and wellness, an undergraduate degree in nutrition is required to become a nutritionist. Becoming a certified nutrition specialist (CNS) or a certified/clinical nutritionist (CN) requires additional licensing and a postgraduate degree.

Physical Therapist

From sports injuries to arthritis pain relief, physical therapists help clients of all ages improve their range of motion so they can function at their highest level. Physical therapists evaluate their clients’ physical status, consult with them to learn their goals, create a plan of care, and administer treatment through a series of exercises.

The path toward becoming a physical therapist begins with earning an undergraduate degree in a field related to sports medicine, health, or exercise science. From there, advanced degrees in a doctor of physical therapy (DPT) program and licensing are required.

The professional options highlighted above represent a small sample of those available to students who earn their undergraduate degree in the natural sciences.
