What you will study

To begin, you’ll develop your understanding of different scales – particularly those that are much larger or smaller than will be familiar to you. Through the nine topics, you’ll then meet concepts and principles in classical and quantum physics and the space sciences. Alongside each topic, you’ll practise your maths skills, applying them to problems in physical sciences. You’ll also be introduced to computer coding, using the Python programming language.

Topic 1 – Forces around you
You’ll explore the types of forces encountered in everyday life, including elastic and frictional forces, as well as gravitational and electromagnetic forces.

Topic 2 – An introduction to energy
You’ll meet the concept of energy and the idea of energy conservation. You’ll learn about some of the different forms that energy can take, including kinetic energy and potential energy, as well as the notions of work and heat.

Topic 3 – Material worlds
You’ll examine how the microscopic structure of materials – at the level of atoms, ions, and electrons – explains some of the ways in which materials behave, through the concept of chemical bonding.

Topic 4 – The quantum realm
This topic will introduce you to the world of quantum phenomena, including the uncertainty principle, wave-particle duality and quantum numbers in atoms – leading to an understanding of the periodic table.

Topic 5 – Energy in society
You’ll explore different fuel sources and look at how energy is used to heat our homes and in transport.

Topic 6 – Nuclei and particles
You’ll learn about the subatomic components of the world around us, including radioactivity and the fundamental particles of matter, as well as the processes that govern their interactions.

Topic 7 – Components of the Universe
You’ll explore the galaxies, stars and planets that make up the Universe and understand how astronomers are able to study objects that are very distant from Earth, including exoplanets and dark matter.

Topic 8 – Exploring the Solar System
You’ll discover for yourself how the various planets, moons, asteroids and comets of our Solar System are explored using landers and remote-sensing spacecraft.

Topic 9 – How the Universe works
You’ll learn about the expansion and cooling of the Universe, how it evolved from the Big Bang to the present day, and its likely future.

Practical work
Some topics include home-based experiments, which you’ll carry out using everyday items. You’ll also conduct two online practical activities: based on data from a weather station and using a radioactive particle detector called a cloud chamber. The online activities provide you with opportunities for collaborative teamwork with your fellow students.

Computer programming
You’ll also be introduced to computer coding, using the Python programming language. Throughout your learning, in a series of dedicated study weeks, you’ll develop your understanding of coding and apply your newly developed skills writing simple programs to solve physical science problems.

You will learn

You’ll learn key physics, astronomy and planetary science concepts and develop your own scientific thinking. You’ll learn fundamentals of computer programming relevant for applications in physical sciences and practice applying your mathematical skills to problems in physical sciences. You’ll also develop your skills for learning online, for working collaboratively, and for reflecting on your own development.

Vocational relevance

While exploring a variety of interesting topics, you’ll develop your problem-solving abilities and improve your computing, mathematical and communication skills. These are valued in all work contexts, but particularly in jobs requiring a precise and quantitative approach.

Teaching and assessment

Support from your tutor

Throughout your module studies, you’ll get help and support from your assigned module tutor. They’ll help you by:

  • Marking your assignments (TMAs) and providing detailed feedback for you to improve.
  • Guiding you to additional learning resources.
  • Providing individual guidance, whether that’s for general study skills or specific module content.
  • Facilitating online discussions between your fellow students, in the dedicated module and tutor group forums.

Module tutors also run online tutorials throughout the module. Where possible, recordings of online tutorials will be made available to students. While these tutorials won’t be compulsory for you to complete the module, you’re strongly encouraged to take part.


The assessment details for this module can be found in the facts box.

You’ll submit four TMAs (tutor marked assignments) contributing 39% to your overall score (7%, 6%, 13% and 13%, respectively). We’ll assess you on the activities you complete as part of the topics, as well as the practical and computer-programming tasks.

You’ll sit an examination at the end of the module, which contributes 61% to your overall score. We’ll base the examination around materials such as articles, data, figures and graphs. These materials will be available in advance to help you prepare. As well as assessing your knowledge and skills, this exam will give you practice for exams you’ll sit at Stages 2 and 3 of your qualification which affect its classification.

The assessment details for this module can be found in the facts box.

Ways to pay for this module

Open University Student Budget Account

The Open University Student Budget Accounts Ltd (OUSBA) offers a convenient 'pay as you go' option to pay your OU fees, which is a secure, quick and easy way to pay. Please note that The Open University works exclusively with OUSBA and is not able to offer you credit facilities from any other provider. All credit is subject to status and proof that you can afford the repayments.

You pay the OU through OUSBA in one of the following ways:

  • Register now, pay later – OUSBA pays your module fee direct to the OU. You then repay OUSBA interest-free and in full just before your module starts. 0% APR representative. This option could give you the extra time you may need to secure the funding to repay OUSBA.
  • Pay by instalments – OUSBA calculates your monthly fee and number of instalments based on the cost of the module you are studying. APR 5.1% representative.

Joint loan applications

If you feel you would be unable to obtain an OUSBA loan on your own due to credit history or affordability issues, OUSBA offers the option to apply for a joint loan application with a third party. For example, your husband, wife, partner, parent, sibling or friend. In such cases, OUSBA will be required to carry out additional affordability checks separately and/or collectively for both joint applicants who will be jointly and severally liable for loan repayments.

As additional affordability checks are required when processing joint loan applications, unfortunately, an instant decision cannot be given. On average the processing time for a joint loan application is five working days from receipt of the required documentation.
