Natural sciences: The three levels & career initiatives

Natural science is an attribution that outlines several categories in science that’s mainly concerned with matter, energy, their reaction and transformation. Natural science department in numerous universities across the United States and around the world is structured in an interdisciplinary format that draws from the various science fields and even math.

Natural science is primarily divided into three categories namely; physics, biology and chemistry whereas each disciple is studied independently in schools, colleges and universities. The degree program in natural science incorporate real-time course worse from many different fields including astronomy as well besides the other three!

While specific degree nurture students for a more specialised career track, a much broader program provide graduates some flexibility as they search for employment. The different options allow individuals to practice their expertise for career advancement. Before we move towards defining the career initiatives, let’s learn about the three levels of natural sciences.

  • Biology

Biology is the study of all living organisms such as humans, animals, plants and others. It’s subdivided into separate areas of interest like human biology, development biology, immunology, microbiology, evolutionary biology, ecology, molecular and cell biology. The subcategories provide a more narrow approach where students can further master their skills and studies.

Most colleges however have a core requirement asking for all majors to be completed especially if you’re pursuing a medical career. The broad program also covers chemistry and physics that interlink with each other in several ways.

  • Chemistry

Another major branch of natural science includes Chemistry which, like biology also has various sub-divisions. Analytical, organic and physical chemistry are the three primary areas whereas if you look at the core degree requirements, the list would cover inorganic chemistry, instrumental analysis, quantitative chemistry and cellular biochemistry.

Theories, practical uses of chemical instruments and numerical inferences all are considered. Major outcomes after successfully completing the program include expertise in laboratory, solving and explaining problems, comprehend chemical theories and practices, present results backed by valid proof. A research institute is a good place to apply as a chemistry lecturer or department in-charge!

  • Physics

This particular field has gone ballistic with time as new discoveries are made and researches are performed. Physics deals with the laws of nature and properties of various existing matters. It covers a wide-range of subcategories such as electronics, magnetism, quantum physics, thermodynamics, optics and waves, astronomy. Students enrolled in the program will explore and participate in different research projects to gain real-time experience. Physics is derived heavily from calculus and maths that plays a crucial role.

  • Other categories

Besides chemistry, physics and biology; natural science also looks into geology, psychology, mathematics, computer science and biochemistry. These areas are frequently represented in high-schools and colleges combining the features of matter, energy and elements that exist in the natural world around us.

Being part of a collective group, the disciples usually overlap drawing students from several different areas seeking advance or targeted degree programs. For instance, biochemistry students usually take mathematic classes, psychology covers a certain segment of biology and its sub-fields like physiology and anatomy.

Career paths

  • Environmental scientists

A degree in natural sciences prepares students for entry-level employment opportunities in environmental science. These scientists work to improve and preserve the natural environment usually found working in laboratories or fields.

  • Food scientists

Food scientists are generally associated with agriculture and food industry whereas some may also work with food production companies. More technical type jobs include soil study, to improve its quality and crop yield.


Forensic science technicians and zoologists are other career paths to choose after completing the degree program in natural sciences. The above details clarified much about the field and relevant employment opportunities.
