Science: concepts and practice

In this module, you’ll explore the ideas that underpin the study of science disciplines at a higher level. Following a week exploring scale, each subsequent week focuses on a particular area – biology, chemistry, earth science, environmental science and physics/astronomy. Online materials and teaching include interactive and audio-visual media combined with collaborative and independent activities. You’ll develop practical skills throughout and in two distinct blocks – focusing on observation and control of variables, where you’ll choose activities suited to your interests. In the final five weeks, you’ll choose two subject areas to study in more detail.

What you will study

Each week you’ll study a self-contained topic, including the following:

Scales in space and time
Scale – dealing with the minuscule to the massive, over milliseconds to millennia – is central to all the sciences. You’ll go to the absolute limits of what we can measure – all through a study of an oak tree!

Rocks: recycling the planet
You’ll use a digital collection of minerals and rocks to learn about the materials that make up the solid earth; the processes by which they are transformed into rocks; and how rocks reveal their history.

Geological time
Earth is 4.6 billion years old. How do we know that? How do we know the history of life on earth? You’ll gain an understanding of the methods that are used to determine relative and absolute ages of rocks and the processes that formed them.

Plate tectonics
Plate tectonics – the process that allows earth’s interior, surface and atmosphere to interact – constantly reshapes the earth. You’ll study evidence for the theory of plate tectonics, one of the most influential ideas in science.

Cycles
Biogeochemical cycles describe how chemical elements cycle through living things and the physical environment. You’ll study three important cycles – water, carbon and nitrogen – and how human behaviour can disrupt them.

Ecological interactions
Ecosystems contain many interlinked biological components interacting with their physical environment, yet there are consistent patterns in the way energy flows through them. These patterns allow us to explore, describe and compare ecosystems, necessary for understanding disruptions.

Environmental change
Ecosystems react to environmental changes caused by both natural and human factors. You’ll learn about natural environmental change and what happens when an invasive species is introduced to an unprepared ecosystem. You’ll understand how we know that environmental change is taking place and how it can be managed.

Forces around you
Forces are central to the motion and stability of the world around us. You’ll learn how to identify and manipulate forces in a range of everyday situations.

Introduction to energy
Energy is another central concept which will be re-visited. This week looks at potential and kinetic energy and explores the concept of heat and temperature.

Material worlds
You’ll explore the materials which make up the world around you and learn how to describe and record your observations of the physical behaviour of materials. You’ll link the macroscopic world to the microscopic by examining the behaviour of the particles from which materials are formed.

The quantum realm
Quantum mechanics is a big idea for understanding the world of atoms. You’ll learn how this is important for processes in physics, chemistry and even biology.

Why chemical reactions happen
You’ll explore chemical change through understanding how particles interact and rearrange, and learn the rules that govern these interactions, allowing you to make predictions about chemical behaviour.

Make me a molecule
You’ll discover how knowledge of the microscopic world enables new materials to be created and how everyday items can be both made, and made better.

Energy in chemistry and the life sciences
Beginning with the nature of chemical bonds in simple molecules, you’ll explore how living cells transform and distribute energy, why we can’t run marathons as fast as we sprint 100 m, and the amazing capability of our eyes and ears as detectors of light and sound waves.

DNA: life’s replicating book of recipes
You’ll learn about the twin functions of DNA, as store of the information required for life, and as a molecule capable of replication, allowing its information to be inherited.
 
Proteins: how DNA makes life
Proteins are the means by which inherited information is turned into life. This topic provides an introduction into how these fascinating molecules are made and the myriad of essential functions they carry out.

The multicellular organism: cells in harmony
The basic unit of life is the cell; most plants and animals are multicellular organisms. You’ll learn how, in a multicellular organism, different cell types are produced from the same set of instructions, and how the health of multicellular organisms depends on each of these cell types working together.

Energy in society
In your third look at energy you’ll explore the science of powering the world! You’ll look at fossil fuels, nuclear energy and renewable energy, and will meet one of the most famous equations in science, E = mc2.

You’ll also choose two topics that you find most interesting or are going to study at higher level. You’ll go on to complete investigations tasks on your chosen topics, and pick one to prepare a short presentation on:
  • Biodiversity and evolution – Life on earth is diverse. To discover why you’ll learn about the relationship between an organism and its environment, and how intense competition between organisms really does make life all about ‘the survival of the fittest’.
  • How chemical reactions happen – You’ll consider the driving forces that cause new molecules to be made and gain a deeper understanding of the role that energy and entropy play in chemical processes.
  • The earth: atmosphere to core – Much of planet earth cannot be seen, so how do earth scientists find out about its inaccessible interior? You’ll learn how the answers can come from chance events such as earthquakes as well as planned experiments and a study of the rocks at the surface.
  • Living in a changing climate – Earth’s climate is changing. How do we know what is happening and how can we predict what might happen in the future? How big are the challenges we face and who should we believe when there are conflicting statements about climate change? You’ll learn how to make an informed decision about our priorities for a more sustainable future.
  • Components of the universe – This topic addresses the universe, from the smallest asteroid to the largest galaxies. You’ll discover a missing component to the universe, taking you right to the edge of current research.

The two distinct practical blocks cover (1) observation and (2) controlling variables. In the first, you’ll explore making observations and accurately recording them. You’ll take weather station readings and, in a team of fellow students, access a weather-data archive to address a question posed by your tutor. You’ll also undertake an online experiment from your choice of scientific discipline. In the second, you’ll take part in a group activity. You’ll then have the choice of one activity from biology; chemistry; physics; earth science; or environmental science and ecology.

You will learn

A key aim of the module is to continue your development as an independent learner so that when confronted by something you don’t know, your response is ‘I don’t know that, how can I find out about it?’, rather than ‘I haven’t been taught that.’ So, alongside developing your understanding of key concepts in the various sciences, to enable you to embrace new ideas with increasing confidence, you’ll develop the following skills:

  • communication skills
  • collaboration skills
  • observation, investigation and practical skills
  • mathematical skills
  • information gathering, analytical and interpretative skills
  • reflective practice around your skills development.

Vocational relevance

The following are activities you’ll engage in:

  • collaborative and online practical work
  • report writing
  • finding and communicating information to others
  • self-assessing skills development.

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.

Assessment

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

Three of the six TMAs will be composed largely of activities you will do as part of your weekly studies, with little extra work required. The practical blocks will have one TMA each associated with them, assessing practical and collaborative skills. The final TMA will focus on a presentation.

The examination will be based 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, the examination is designed to be a simple introduction to taking examinations at university level. It will give you practice ahead of examinations that you will meet in your further studies and which will have a bearing on the classification of your degree.

Laboratory schools

The School of Life, Health and Chemical Sciences offers optional laboratory schools in Milton Keynes at an additional cost. Laboratory schools are not part of this module but may be of interest if you wish to gain relevant hands-on laboratory experience.

Further information and instructions for booking are on the SS011 website.

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.
