Natural Sciences BSc

London, Bloomsbury
Natural Sciences BSc (2025)

Natural Sciences enables students to combine science subject areas, known as streams, reflecting the multidisciplinary nature of high-quality, internationally leading research undertaken at UCL. The BSc programme follows the same structure as the first three years of the MSci.

If students are unsure whether to pick the BSc or MSci, they are advised to apply for the MSci initially, although transfer between the two programmes up to the end of the third year is straightforward.

Course overview

The vision behind the Natural Sciences Programmes is to offer distinctive cross-disciplinary subject combinations that would not be available within any single department, by exploiting a vast range or existing scientific learning opportunities.

We want our students to be comfortable crossing artificial subject boundaries, collaborating, and making connections in their professional life, whilst also benefitting from a deep level of expertise and knowledge that ensures they can compete on specialist terms for employment or further study with graduates from single discipline programmes. 

We achieve this balance through carefully structured curricula that enable our students to access teaching across departments and divisions, at all undergraduate levels of study. Many classes are taken alongside students who are studying for degrees in a single discipline.

The programme is sub-divided into many different subject “streams”, which broadly reflect major research themes and similar specialist science degree subjects. A combination of two streams is selected early in the programme from a long list of available options and is followed for the duration of the degree. The curriculum design for each stream combination ensures that in years one and two there is strong cross-disciplinary emphasis on core knowledge, whilst in the third and fourth years there is scope for students to exercise their diverse interests.

What this course will give you

Ranked in the top 4 in the UK by the QS World University Rankings by Subject 2022 for Natural Sciences, our degree programmes allow you to study a distinctive cross-disciplinary science curriculum by combining classes across different departments.

We want you to be comfortable crossing artificial subject boundaries, collaborating, and making connections in your professional life, whilst also benefitting from a level of expertise and knowledge that ensures you can compete on specialist terms for employment or further study with graduates from single discipline programmes.

You will study science subjects with the same rigour and quality as students on single subject programmes. Many of you classes will be taken alongside students who are studying for degrees in a single discipline.

Teaching and learning

In each year of your degree you will take a number of individual modules, normally valued at 15 or 30 credits, adding up to a total of 120 credits for the year. Modules are assessed in the academic year in which they are taken. The balance of compulsory and optional modules varies from programme to programme and year to year. A 30-credit module is considered equivalent to 15 credits in the European Credit Transfer System (ECTS).

Upon successful completion of 360 credits, you will be awarded a BSc (Hons) in your chosen Natural Sciences stream.


Please note that the list of modules given here is indicative. This information is published a long time in advance of enrolment and module content and availability is subject to change. Modules that are in use for the current academic year are linked for further information. Where no link is present, further information is not yet available.

Options are available from within Genetics, Biomedical Sciences, Molecular and Cell Biology, Neuroscience and Psychology, Chemistry, Physics, Medical Physics, Astronomy, Earth Sciences, Mathematics and Statistics, Science and Technology Studies.

The main features of the programme may be described as follows:

The broad foundation - You will begin by choosing a foundation programme according to your subject interests and background. This will provide a broad coverage of selected scientific topics and perspectives, mathematical know-how and computer practice.

The stream combination - You will choose two complementary science subjects (streams) from the list of allowed combinations. The combinations are designed to lead to specialist knowledge rather than an overview of an entire discipline. The choice is made early in your first year and followed for the rest of the degree.

The degree core - Natural Sciences core modules will challenge you to work in groups with other Natural Sciences students and to develop your skills as a science professional, for instance by completing a group computer investigation, producing a piece of science communication, or designing a science exhibition.

The major - In year three you can designate one stream as the “major” and undertake a greater proportion of your studies in that area. If you take the integrated Masters course you must define a major stream as preparation for a research project and Masters-Level taught courses undertaken in the final year.

Information on the allowed stream combinations and stream-specific entry requirements can be found on the Natural Sciences website.

Compulsory modules

BSc/MSci Natural Sciences 2 unit container module

Compulsory module(s)

In the first term you will select three foundation modules from the following six areas, serve as an introduction to the subject areas of the streams that are offered. You will make your selection according to your background qualifications and scientific interests:

  • Biological and Life Sciences
  • Chemistry
  • Earth Sciences
  • Physics and Astronomy
  • Statistics
  • Science and Technology Studies

You also will take an appropriate module in mathematics, tailored to your background and foundation module choices.

You will then choose two streams, to be studied from the first year second term onwards, subject to the allowed stream combinations.

The programme offers streams in the following areas

  • Astrophysics
  • Biomedical Sciences
  • Genetics, Evolution and Environment
  • Geoscience
  • History, Philosophy and Social Studies of Science
  • Inorganic and Materials Chemistry
  • Mathematics and Statistics*
  • Medical Physics
  • Molecular and Cell Biology
  • Organic Chemistry
  • Neuroscience and Psychology
  • Physical Chemistry
  • Physics

* May only be pursued as a minor stream after year two

Information on the available streams, allowed stream combinations and stream-specific entry requirements can be found on the Natural Sciences website.

Core streams

You will take 45 credits from each of your two streams. Within your streams there may be some modules that are compulsory and some that are recommended, as well as options that you can choose if they do not create a timetable clash that cannot be resolved.

At the end of the second year, you will choose one of the streams as a major stream.

Compulsory module(s)

You get to chose 15 credits from a list of core modules in year 2:

NSCI0036 Programming For Scientists - students learn the fundamentals of coding in the Python programming language, one of the most popular programming languages which is widely used in science and other disciplines.  They perform computations, analyse and present data and make predictions, and will be in a position to learn more sophisticated computational techniques including mathematical modelling.  

NSCI0038 Science For All - students reflect on and understand inequity in science learning and in the production of scientific knowledge; and to learn about methods and practices being developed to address some of the issues.  They will think about creative forms of engagement through visiting a number of sites where informal science learning may take place and learn how to conduct effective evaluations. Building on this reflective and theoretical foundation, they work in teams to plan, create, and evaluate a science outreach activity.

NSCI0039 Science Communication - students will examine various forms of science communication and consider how the content of the message may be affected through communication. They are also be encouraged to reflect on exclusionary practices in science communication to engage with the distrust felt by some members of society towards science and scientists.  They learn how to craft effective communications for different types of audiences and explore some possible ways of challenging exclusionary practices. 

Optional modules

You can select one elective module in year two, worth 15 credits. Your elective may be selected from any department within UCL, if you meet the pre-requisites and are given permission by the department that teaches it.

Core streams

You will take 45 credits in your minor stream and 75 credits in your major stream. The credit for the major stream includes a compulsory 15 credit literature review module. Within your streams there may be some modules that are compulsory and some that are recommended, as well as options that you can choose if they do not create a timetable clash that cannot be resolved.

Compulsory module(s)

You will take NSCI0004 - Literature Project. This module involves writing a critical review of published work in a key topic area related to your major stream. After completing the module you should be able to:

  • Identify and develop a review topic in consultation with UCL academics
  • Interrogate appropriate research databases using search terms to find relevant literature
  • Critically assess the literature and make judgements about research quality
  • Plan and time-manage your review independently
  • Develop a professional researcher-researcher relationship with a supervisor
  • Write a fully referenced review describing a research topic
  • Construct and present an oral presentation for a scientific audience
  • Communicate scientific concepts to experts and non-experts alike

Your learning

A variety of teaching methods are employed, including lecture classes, practical sessions such as laboratory, computing practical sessions or fieldwork (dependent on stream choice), and small-group tutorials.

You will also be expected to spend a substantial amount of time on coursework and private study.

Some streams involve optional modules with field trips, typically these are in Earth Sciences.

Contact hours can vary from stream to stream, reflecting how different scientific disciplines may be more practical and laboratory-based or theoretical and involve extensive reading or searching of literature. Expect something in the range of 20-35 hours of in-person and private study a week.


Each module has its own intended learning outcomes, which are used to align the individual assessments. For example, practical assessments such as lab reports or scientific computing assignments may be designed to help you develop techniques of analysis and enquiry, and/or analyse data to draw conclusions.

Group work will allow you to tackle larger and more complex problems and develop your professional and collaborative skills, whilst independent work will allow you to demonstrate and explore your initiative and develop your critical skills.

Examples of assessment you may encounter include written examinations, oral examinations or presentations, podcast/video assessments, poster assessments, practical assignments and reports, multiple choice questionnaires, quizzes, and coursework problem sheets. Many of your modules will feature an unseen examination component that carries a large proportion of the marks, whilst some modules are entirely coursework based.

The foundation of your career

Our programme is one of the largest and most comprehensive Natural Sciences courses in the UK. Our graduates have progressed to a diverse range of exciting graduate careers, including research, teaching, finance, management, consulting, technology, and science journalism, to name just a few.


On completion of your degree you will be able to

  • demonstrate coherent, detailed knowledge in two complementary scientific disciplines
  • apply accurately established techniques of analysis and enquiry
  • describe and comment upon current scientific research and advanced scholarship​

Crucially, you will also benefit from the opportunity to adapt and apply your learning across boundaries, developing your abilities to draw connections between topics and develop unique insights. This may make you a highly attractive candidate for some some career opportunities.

You should expect to compete successfully for jobs and further study opportunities in the sectors relevant to your main areas of study. Recent graduates have gone into areas such as technology, finance, law and the civil service. Further postgraduate study is also a common destination for leaving students. The most popular industry sectors for Natural Sciences graduates include:

  • Accountancy & Financial Services
  • IT, Technology & Telecomms
  • Publishing, Journalism, or Translation
  • Teaching or other educational activities

During your studies you will gain experience using e-learning technologies and you will produce a variety of outputs such as word-processed documents, posters and infographics, presentations, or recordings. You will write your own computer code and will develop your oral and written communication of science through a diverse range of assessments.

Problem solving and data analytic skills are extensively developed across a large fraction of the modules that you will have access to, and the ability to apply these skills to tackle unseen and interdisciplinary problems is challenged and evidenced via project work. Independent critical thinking and creativity are similarly encouraged and developed. All this project work requires excellent team work and leadership skills, and ability to manage projects. You will be trained in these skills in the programme core modules. Some students develop these attributes further via roles such as Student Academic Representative, Transition Mentor, or leadership roles within the NatSci Student Society.

In the third year literature project module, “critique” and “insight” are key assessment criteria, and the meanings of these terms are discussed in workshops. You will develop your critical thinking and creativity as you move through the programme, via assessments requiring increased levels of sophistication such as open-ended and long-form essay questions or journal clubs.

These attributes are common to all Natural Sciences students, but you will develop greater sophistication in some aspects through the study of your two streams. For instance, students who specialise in Mathematics and Statistics or Physics can expect to develop high levels of proficiency in computing; students who take History, Philosophy and Social Studies of Science can expect to become highly developed communicators with excellent understanding of ethical issues in science. Some students may also have opportunities to use specialist instrumentation.


Society for Natural Sciences Accredited Degree. These accredited programmes have achieved the standards set out in the Society’s accreditation framework and are recognised as offering outstanding quality interdisciplinary science education, providing students with excellent learning opportunities and skills development to prepare them for future careers in research, education, business or industry.
