Fire ecology free course icon Level

Science, Maths & Technology 

Fire ecology

This course explores the role of fire as a natural disturbance in ecosystems. It introduces the concept of a fire regime and its influence on the type and distribution of organisms that occur in fire prone ecosystems. It also looks at some of the adaptations of plants that have evolved in these ecosystems and how animals either avoid or exploit the consequences of fire as a natural disturbance. Finally it examines how fire can increase biodiversity by generating a mosaic of habitats within an ecosystem and briefly addresses some of the consequences of climate change and global warming on the intensity and frequency of fires.

Blood and the respiratory system

‘Don’t hold your breath’ is an expression you’ve probably heard many times, but may not have thought too much about. In this free course, Blood and the respiratory system, you’ll study why respiration is so important for life, including how air enters and leaves the lungs, how oxygen is transported in the blood, the many dynamic factors that control breathing, and some diseases that affect respiration.

Digital thinking tools for better decision making

Ever since the very beginning of humanity, tools have played a pivotal role in who we are and what we do. Tools for recording, processing and communicating information have a time-honoured history – from the clay tokens used in Mesopotamia to mechanical calculating machines. The invention of the digital computer has boosted the scale, speed and reach with which thinking tools extend our natural capabilities. This free course, Digital thinking tools for better decision making, starts by placing thinking tools in their historical context and concludes with an examination of their future. During the course, you’re introduced to a wide variety of digital thinking tools. You will apply these tools in many practical activities and case studies, solving problems that involve finding and evaluating information, performing calculations and drawing reasoned conclusions.

Scales in space and time free course icon Level

Science, Maths & Technology 

Scales in space and time

Scale – dealing with the miniscule to the massive, over milliseconds to millennia – is central to all the sciences. In this free course, Scales in space and time, you’ll go to the absolute limits of what can be measured – all through a study of an oak tree! By studying it you will be introduced to concepts in physics, chemistry, biology and life-sciences, and Earth and environmental sciences. Across these multiple disciplines you will meet time scales that include ages, durations and rates, and size scales including distances in three dimensions, which underpin areas and volumes.

Understanding autism free course icon Level Badge icon

Science, Maths & Technology 

Understanding autism

Learn about autism, one of the most challenging long-term conditions of the century. This free course, Understanding autism, introduces the autism spectrum, how it is experienced by individuals and families, and why it has become a global concern. The course explains how understanding of the autism spectrum and approaches to diagnosis and care have evolved. Key scientific approaches to studying autism are explained and illustrated, alongside substantial use of different personal perspectives. The course culminates with key topical issues such as autism in adulthood, and missed diagnosis in women. The course is suitable for all who need a clear, authoritative overview, and does not require prior knowledge of science or social science. It uses text, images and audio-visual media.

Learning from major cyber security incidents

  As a society, we are now almost always connected to the internet and rely on it for many different day-to-day activities. However, this dependency on the internet can make us vulnerable to attacks.  Once a connected device is compromised, it is not only that particular device that is affected – it can also be used as a springboard to attack other devices in the same network and in others.  In this connected world, it is also inevitable that personal information is stored in large-scale government and commercial databases. Unfortunately, breaches of these large-scale databases happen fairly frequently and, when they do, personal information can be leaked which will make you, and millions of others affected, vulnerable to scams and other identity crimes.  This course analyses several cyber security incidents and looks at what lessons can be learned.

Introducing mammals free course icon Level

Nature & Environment 

Introducing mammals

Mammals come in a bewildering variety of shapes and sizes, and yet all species have some characteristics in common. These similarities justify the inclusion of all such diverse types within the single taxonomic group (or class) called the Mammalia. This free course, Introducing mammals, offers a starting point for the study of mammals. It will establish their rich diversity, while highlighting the common features that define the group.

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.

Nature & Environment 

Aquatic mammals

Mammals come in a bewildering variety of shapes and sizes and yet all of the 4700 or so species have some characteristics in common, which justifies the inclusion of diverse types within a single group. Although mammals evolved on land, a number of species have become adapted to spending part or all of their lives in water and it is these mammals that you are going to concentrate on in this course. You will meet some aquatic mammals, find out how we can study them, consider their evolutionary history and read about human impacts on one iconic group.
