Practising science: Reading the rocks and ecology
Have you ever wondered how scientists analyse the environment? This free course, Practising science: Reading the rocks and ecology, introduces you to the techniques used by science students at residential schools. You will learn how to determine where rocks have come from and how they were made. You will also examine the processes involved in ...

Point estimation
This free course looks at point estimation, that is, the estimation of the value of the parameter of a statistical model by a single number, a point estimate for the parameter. Section 1 develops some aspects of maximum likelihood estimation. In particular, you will find out how to obtain the maximum likelihood estimator of an unknown parameter,...

Interpreting data: Boxplots and tables
This free course, Interpreting data: Boxplots and tables, is concerned with two main topics. In Section 1, you will learn about another kind of graphical display, the boxplot. A boxplot is a fairly simple graphic, which displays certain summary statistics of a set of data. Boxplots are particularly useful for assessing quickly the location, ...

Number theory
This free course is an introduction to Number Theory. Section 1 provides a brief introduction to the kinds of problem that arise in Number Theory. Section 2 reviews and provides a more formal approach to a powerful method of proof, mathematical induction. Section 3 introduces and makes precise the key notion of divisibility. The Division ...

Forensic science and fingerprints
This free course, Forensic science and fingerprints, covers how science can make fingerprints easier to study, how they are used in court and some of the questions about the extent to which fingerprint identification is sound and scientific. Students will learn the principles used in classifying and matching fingerprints (often called marks).

Innovation through representation
Innovations are realised through design, and some of the most useful tools in the designer's toolbox are the representations that are used to move from a vague idea, to a concept, and then to a realised product, service or system. This free course, Innovation through representation, explores what innovation is and how representations are used to...

More working with charts, graphs and tables
When you encounter maths or technical content you'll need to know how to interpret this information, and possibly to present your own findings in this way. This free course, More working with charts, graphs and tables, will help you to develop the skills you need to do this, and gain the confidence to use them. This free course builds on our ...

Surviving the winter
In this free course, Surviving the winter, we study one aspect of the fluctuating nature of an organisms environment. We consider how organisms living in a temperate climate, such as that in Britain, are adapted to cope with winter. You will see that there is much diversity of adaptations among organisms, with different species coping with the ...

Icy bodies: Europa and elsewhere
The new discipline of astrobiology that is, the science of searching for extraterrestrial life, is not only rapidly growing, but has also captured the public imagination. This free course, Icy bodies: Europa and elsewhere, examines the emergence of icy satellites of distant planets as potential sites of extraterrestrial life, looks at the ...
