Know About Science Stream Subjects

Those of you who are preparing for the 10th standard board exams are most likely surrounded by questions like which stream to choose. Whether to take a road less travelled or study subjects opted by many? And what are the career prospects in different fields? Self-introspection is the key to unlocking the box of your queries!  As you are aware, you can opt for either Science, Commerce, or Arts stream after 10th standard. Before choosing a stream, you should conduct an in-depth analysis of your strengths and weaknesses and then select a stream that aligns with your interests and professional goals. While the Commerce and Arts stream subjects have their own advantages, methodologies, and career prospects, we, in this blog, will shed light on various Science stream subjects. But before that, let us try to understand the reasons for choosing this stream. 

Why Pursue the Science Stream?

In the words of Edward Teller- “The Science of Today is the Technology of Tomorrow”. The Science stream subjects encompass the elements of both scientific theories and practical concepts. Not only do these subjects impart in-depth knowledge of the physical, chemical, and biological aspects of the universe but also equip students with analytical and problem-solving abilities. The subjects also help to understand the effects of natural and artificial processes on the world. Thus, the students who opt for the Science stream have a wide range of career opportunities. Bioinformatics, Dental Science, Space exploration, Computer Science, Metallurgy, Pharmaceuticals, Biotechnology, Nanotechnology, Mechanical Engineering, and Forensic Science, are some of the many career paths you can choose after studying Science stream subjects

Science Stream Subjects: Overview

The Science Stream is subdivided into 2 branches namely, the non-medical stream (PCM) and Medical stream (PCB). With Physics and Chemistry as common subjects, the difference between the two divisions lies in the selection of the third subject. While Maths is opted for by students who want to kickstart their careers in professions like but not limited to Engineering, Architecture, and Commercial Pilot, Biology is chosen as a subject by those who want to pursue a career in Medical Science. Apart from the above-mentioned subjects, the students also have to study English or Hindi along with an elective subject. Informatics Practises, Physical Education, Computer Sciences, Engineering Drawing, Economics, Home Science, and Psychology are some of the popular electives. Given below is a comprehensive list of the Science stream subjects:

Welcome To The World Of Periodic Tables!

Chemistry is simply the study of the building blocks of life, i.e. atoms and matter. This Science stream subject imparts in-depth knowledge of the properties, composition, and structure of matter. With the advancement in technologies, new areas have started emerging in the field of Chemistry Biomolecules, Synthetic Materials, Industrial Chemistry, and Natural Resources. The theoretical concepts are accompanied by practical experiments to make concepts easy. With Organic and Inorganic Chemistry as the main sub-divisions, the subjects cover various concepts through topics like Surface Chemistry, Atomic Structure, Chemical Kinetics, and Chemical Bonding. 

Work, Energy, and Power

Considered one of the oldest academic fields, Physics is the study of motion, force, matter, and energy. With the advancement in technologies as well in areas like Nuclear Physics and Mechanics, studying these Science stream subjects will help you develop analytical, decision-making, investigatory, and observational skills. Some of the topics taught in this subject include the Laws of Motion, Electrostatics, Electronic Devices, Thermodynamics, and Kinematics.

Let’s Coordinate Reasoning With Geometry

Mathematics, or what is also referred to as the study of numbers,  imparts knowledge and clears concepts of quantity, structure, and space. In this Science stream subject, you are taught to identify the flow of reason when solving a problem, understand the principles of underlying skills and processes and prove the results through the application of different methods. Calculus, Mathematical Reasoning, Algebra, Probability, and Linear Programming are some of the topics covered in this subject.

Study About The Living Organisms 

Biology is one of the most famous Science stream subjects involved in the study of all living organisms. It imparts extensive knowledge of the different facets of organisms such as physiological mechanisms, molecular interactions, physical structures, evolution, and development. Some of the topics covered in this subject include Cell Structure and Functions, Structural Organisation in Plants and Animals, Human Physiology, and Plant Physiology.  

Learn the language of Computers

Another popular Science stream subject is Computer Science which is very popular among students willing to pursue Engineering or make a career in technical fields. In class 11 Science, Computer Science subject focuses on a particular language like C++, C, JAVA, Python, etc. Students are taught the language over a span of 2 years ranging from basic to advanced levels. They are expected to submit a working code at the end of class 12th as a project.

Additional Subjects

In case a student fails to score well in any main subject, he/she can count the marks of the additional subject can take admission. Many schools have a mandatory additional/optional subject to choose from. After an additional subject, the total no. of science stream subjects in classes 11 & 12 is 6. In the non-medical and medical stream physics, chemistry, mathematics, and biology are mandatory. Here are the optional subjects students can opt for:

Physical Education

Physical education is an optional subject and quite scoring. There is a 30 marks practical and 70 marks theory subject. The subject was introduced to bring changes and improvements in human bodies with regular exercise. The physical education practical included project work, track races, long jump, etc


Economics is a mandatory subject in the commerce stream but also a popular choice in the science stream as an optional subject. Economics is an interesting subject and focuses on national GDP, National incomes, micro, and macroeconomics, demand, supply chain, etc. Economics is a great choice as a science stream subject optional.

Advantages of Science Stream Subjects

After class 10th the biggest decision students have to make is deciding the stream. Every stream has its own pros and cons. On average every year 33% of the students opt for the science stream. The Science stream is considered the stream with the toughest curriculum but comes with various plus points as well. Here are all the advantages of science stream subjects:

  1. Science stream subjects are not just about balancing the balance sheet every day. The Science stream is about discovering and learning from the human body to the whole universe. Scientific discoveries, understand how the world works and even the plants and animals around us.
  2. After choosing science stream subjects your career options are not restricted to engineering and MBBA. There are plenty of opportunities in related fields, such as research and development, architecture, data science, etc.
  3. One of the best advantages of choosing science stream subjects over others is that if you want to switch your field from science to business management, journalism, or even law you will be eligible to apply for these courses. However, a student from the arts stream is not eligible to pursue MBBS because of its subjects.
  4. There is nothing scary or boring about science stream subjects if you have an interest to learn and grow every day. The skills required in science stream subjects help in developing students into more progressive and bright individuals.
  5. By choosing science stream subjects you will have an opportunity to contribute to mankind through your inventions. Science stream students are capable of developing cures, treating various diseases, and much more.
