Science, Maths & Technology 

Discovering chemistry

Chemistry lies at the centre of our modern life, playing a part in areas as diverse as the development of new drugs and materials, analysing our environment through to more mundane activities such as washing your clothes and making your tea. But to truly understand the role chemistry plays you need to have a sound grasp of a number of fundamental principles. This free course, Discovering chemistry, introduces you to some of these concepts, beginning with the idea that everything that you can see is made of building blocks called atoms. This leads on to a look at the chemical elements and how they are arranged in the Periodic Table, enabling chemists to rationalise patterns in their chemical and physical behaviour. Next you will consider chemical reactions, specifically how atoms combine with other atoms to form molecules, and how molecules combine with other atoms or molecules to form bigger molecules. You will meet simple (tried and tested) theories to explain the bonding in molecules and at how their shapes may be explained, and indeed predicted. And in a wider sense you’ll be looking at why reactions happen at all and how fast they go. This is also a beginner’s level course in the language of the chemist; you’ll learn about symbols, formulas and how chemical equations which represent reactions are constructed. Finally you will see how chemists ----- atoms and molecules, essential for making up solutions of a known concentration in order to carry out a reaction, or performing a chemical analysis.

Metals in medicine free course icon Level

Science, Maths & Technology 

Metals in medicine

This free course, Metals in medicine, focuses on the use of metals and their compounds in the production of images of internal structures in our bodies and on the role of metal-containing compounds as drugs in the treatment of disease. In terms of medical imaging, the high atomic numbers of many metals, their magnetism and radioactivity have all been harnessed in a range of techniques to provide contrast between tissues and to highlight diseased or otherwise changed tissues. These techniques have become some of the most important weapons in our fight against disease. When considering drugs used for the treatment of disease, your first thoughts might lean towards treatments involving organic compounds. But metals and their compounds have been used for medical applications since ancient times. The use of metal-containing drugs is a wide-ranging, exciting and ever-expanding research area. In this course you will learn the underlying chemistry behind both uses of metal-containing compounds and see their major impact on human health.

The science of alcohol free course icon Level Badge icon

Science, Maths & Technology 

The science of alcohol

Alcohol plays a considerable part in the daily lives of humanity and has done for thousands of years. This free course, The science of alcohol, looks at the science behind the processes of brewing, distilling and vinification, and how many of our beverages are made. A historical aspect is also covered showing how the modern production techniques have developed from ancient methods, and how scientists ensure that products are safe to drink. The course also looks at the biological effects of alcohol, and how it affects the human body.

What chemical compounds might be present in drinking water?

Do you want to know what’s in the water that you drink? This free course, What chemical compounds might be present in drinking water?, examines the chemical compounds that occur in drinking water. A high level of certain anions in water can cause environmental pollution and health problems. Cations are also important. For example, calcium salts contribute to the hardness of water and water treatment uses aluminium compounds. Additionally oxidising agents, such as ozone or chlorine, are vital in the disinfection of water. This OpenLearn course focuses on the chemistry of the p-block elements in Groups 13 to 18 of the Periodic Table.

Understanding antibiotic resistance free course icon Level Badge icon

Science, Maths & Technology 

Understanding antibiotic resistance

Antibiotic resistance is a serious threat, compromising our ability to treat infections and increasing the risk of routine surgery. Resistant infections are increasing due to overuse of antibiotics and this has resulted in the emergence of 'superbugs' (bacteria resistant to multiple antibiotics). This free course, Understanding antibiotic resistance, provides the science background underlying antibiotic resistance. It will cover the following questions. What are antibiotics? Why do we need them? How do they work? What is antibiotic resistance? Why is it a problem? What can we do about it?

Iron transport and storage

This free course, Iron transport and storage, looks at the methods that have been developed by organisms for the uptake, transport and storage of iron: a process made more complicated by the insolubility of its oxides and hydroxides. You will examine iron storage in mammals, including humans,. This is achieved by ferritin which stores iron as a hydrated iron (III) oxide an example of biomineralisation.
