Science and society

This interdisciplinary science module extends the scientific understanding and skills you developed at OU level 1. You will explore several contrasting contemporary issues: food security and safety; water; engineering the climate; energy; and personalised medicine. Each topic focuses on questions where an understanding of science is important in decisions which face us as individuals and society. The topics are analysed both scientifically and in terms of four social themes: communication; risk; ethical issues; and decision-making. This module is also a useful means of acquiring the key skills and understanding required for further study of a range of science subjects. 

Modules count towards OU qualifications

What you will study

How can science contribute towards a healthy, happy future for humanity? Can science alone provide the answers?

This on-screen module tackles some of the biggest questions facing humanity. You will study five key challenges to future global well-being: food, water, climate, energy and medicine. As you study these topics, you will also explore the themes of communication, risk, ethical issues and decision making that demonstrate the often impossible task of separating scientific and social issues.

You will develop skills in finding and evaluating information from a range of sources, in communicating scientific ideas and opinions, in collaborative online work, and in practical and analytical skills.

Topic 1: Food: security and safety

How do we feed our rapidly growing global population? How do we tackle the ill-health that results from too much of some types of food and not enough of others?

This topic explores global food security, and asks whether highly technological solutions like the genetic modification of crops are appropriate. You will examine the science behind genetic modification and hence draw your own conclusions about its effectiveness or otherwise.

You will also study the science that informs the dietary advice we receive in the developed world. You will learn how the risks associated with the various components of our diet are assessed, and look critically at how scientists and governments attempt to communicate those risks to us.

Topic 2: Water

How do we provide adequate supplies of water to a growing global population? How do we ensure that our water is safe to drink?

Our blue planet is 70% water, but millions face water crises. You will study the distribution of water in nature and how it is influenced by human activity. You will investigate why nations suffer from water scarcity and how scientific and technological advances can improve fair access to water. You will consider the social issues related to water distribution, testing and regulation through a number of global examples.

This topic also explores the risks associated with contaminated water supplies, discussing cases where arsenic has entered the water supply.

Topic 3: Engineering the climate

Should we deliberately manipulate earth’s climate to counteract human-caused climate change and avoid its worst effects?

Geoengineering is controversial. Why might we want to engineer the climate? How we might design the perfect climate? What are the risks and uncertainties involved, and how might we use scientific information to make informed decisions? You will explore the science and mathematics needed to tackle these issues and how planetary change is measured and modelled. Geoengineering techniques are explored alongside other factors that influence climate change.

The topic explores how climate scientists interact with society, how climate science is communicated and by whom, how people respond to these messages, including climate ‘scepticism’, and the benefits and tensions in using scientific evidence to make decisions about our future.

Topic 4: Energy

How do we meet the ever-increasing global and personal demands for energy?

In this topic you will explore two key scientific and social issues which arise as a result of our demand for energy. The first is the challenge of generating electricity sustainably, and potential risks and benefits of a greater reliance on nuclear power. The second is the challenge of developing sustainable alternatives to crude oil, examining the potential risks and benefits of biofuels, hydrogen as fuel, fuel cells and batteries.

You will also explore the science behind the energy technologies, and how environmental impact can be assessed. Ethical issues are addressed using the concept of energy justice: whether energy systems can be developed to give people access to energy without compromising the quality of life of current or future generations.

Topic 5: Personalised medicine

Modern medicine throws challenging questions for humanity. Recent scientific advances suggest that medical treatments will increasingly become tailored to meet the needs of individuals, a field known as “personalised medicine”. A range of advances in this area of medical science are discussed, including, gene therapy and genomic medicine, the use of stem cells and tissue regeneration.

The topic focuses in particular on how our increased knowledge of genetics and the human genome has impacted on medical treatments, and how this knowledge could be used in the future. You will engage with the ethical issues associated with the research and development of these new technologies, the difficulties in proceeding from initial laboratory research to therapeutic applications, and the evidence for the effectiveness of any clinical use so far.

You will undertake an online practical investigation to assess the effectiveness of a cancer treatment across a range of individuals.

Further investigation

In the final part of this module you will choose an aspect of one of the five topics to update. You will study appropriate scientific literature and write a short briefing note on the most recent developments in the field. This will form part of the final assessment for the module.

This module is delivered entirely online, with audio, video and interactive activities integrated throughout. There are no printed texts.

Teaching and assessment

Support from your tutor

You will be supported by a tutor who will help you with the study material, mark and comment on your written work (TMAs), and whom you can ask for advice and guidance. There will be a number of online tutorials that you can join and access via your computer.

Some activities may involve collaborative work with other students, conducted online with support from your tutor. Participation in collaborative activities may be required to complete some of the assessed work for this module.

    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.
