IB Sciences give you four options to explore, and each path helps you build a different way of thinking.
Whether you take Biology, Chemistry, Physics, or Computer Science, you’ll learn how to ask questions, conduct independent research, test ideas, and explain concepts in clear steps.
In each subject, you’ll work with data, create models, and practice skills that help you think with evidence.
Note that each subject accounts for 20% of the final grade. So it’s important to give the IB science subject of your choice the attention it deserves to score top grades.
1. Biology
IB biology focuses on a diverse array of biological concepts and theories. It explores 8 fundamental areas, which are biochemistry, cells, molecular biology, ecology, evolution, biotechnology, and human physiology.
Alongside these core topics, IB Biology requires you to engage in practical activities and investigations designed to enhance your proficiency in scientific communication, data analysis types, and experimental design.
The primary objective of biology extended essay and biology internal assessment is to cultivate your critical thinking, analytical skills, and capacity to understand and apply scientific principles within the framework of the natural world.
Moreover, the examinations assess your knowledge, comprehension, and expertise across all facets of the subject.
2. Chemistry
Chemistry is an investigative subject that aims to examine the chemistry underlying everyday phenomena.
Chemistry in the IB program demands a high level of independent skills, research work, and personal effort.
For chemistry extended essay and chemistry internal assessment, the goal is to evaluate your understanding of chemistry at the level attained in your coursework by applying practical skills that you’ve acquired.
3. Physics
You can take IB Physics if you want to deepen your understanding of the natural world by exploring concepts, methods, and tools in the subject.
The subject stresses on scientific inquiry in both classroom and laboratory and fosters connection with other science subjects.
IB Physics aims to develop your conceptual understanding, analytical skills, creativity, resilience, problem-solving abilities, and technology skills within a scientific framework.
As you write your Physics IA as well as Physics EE, you will acquire effective communication and collaboration skills and become more aware of the ethical, environmental, economic, cultural, and social impacts of science.
Additionally, the subject will equip you with the necessary knowledge to actively engage with scientific issues and effectively apply what you learn across different disciplines.
3. Computer Science
Computer Science IA focuses on building a digital product for a real user. You plan the solution, create the program, test it, and document each step.
The goal is to solve a clear problem, and your writing needs to show why your decisions make sense.
You gather feedback from the client, and then use the feedback to refine the work, and present evidence that the program performs as intended. Your explanation should describe your design choices, algorithms used, and the reasoning behind your approach.
On the other hand, Computer Science EE is a research paper connected to computer science concepts. Instead of producing a program like in the IA, you explore a specific EE research question.
Your essay can focus on areas such as algorithms, machine learning models, encryption methods, or data structures. Regardless of the topic you choose, you’ll collect information through academic sources or experiments, compare ideas, and form a reasoned argument.
How to Do Well in IB Sciences
Biology, Chemistry, Physics, and Computer Science are technical subjects in the IB diploma course. Here are some useful tips to help you perform well in them:
1. Simplify Your Ideas
Choose an idea you are confident will score you top grades.
Begin by compiling a list of all the experiments you have already conducted in class to get a sense of what constitutes a good experiment. Then once you have the list, choose the experiment that captivates you the most and add a unique twist to it.
Think creatively and explore unconventional approaches.
Your aim should be to generate an original and even slightly eccentric idea, while keeping it simple and within the scope of the assignment.
While the most effective science IA often builds upon a well-established experiment, be cautious not to simply replicate an existing experiment. Instead, adapt it, personalize it, and approach it from a fresh perspective.
2. Develop a Clear Research Question
Formulate a clear and focused research question once you’ve selected a topic for your scientific experiment.
The research question holds the utmost importance in the entire assessment. It should be succinct and informative, and strike the right balance between being too broad and too narrow.
What you’re investigating should be evident to whoever is evaluating your paper. To test this, consider sharing your research question with a friend and see if they can quickly grasp the essence of your experiment.
Fresh perspectives are valuable in these situations since what may seem obvious to you could be ambiguous when taken out of context by someone else.
3. Focus on Personal Engagement
Personal engagement examines how your personal experiences have influenced the design of your experiment. So ensure that you genuinely find your project interesting to get a high score for this criterion.
For example:
Instead of investigating something like the rate of breakdown of hydrogen peroxide, which may have little relevance or significance in your daily life, consider measuring the caffeine content of your favorite type of coffee compared to others.
Your rationale for selecting such a topic could be as simple as being a coffee enthusiast and always wondering which type provides the strongest kick in the morning.
Therefore, while reviewing our suggested topics, try to contemplate whether there is a specific subject that holds unique significance to you and your life.
