4.3.2 Removal of CO
This extract is concerned primarily with the chemistry that underpins the operation of the three-way catalytic converter that is placed in the exhaust systems of motor vehicles in order to reduce the emissions of primary pollutants: carbon monoxide, oxides of nitrogen and volatile organic compounds, including hydrocarbons. Discussion of the various effects of these pollutants and the consequent introduction and refinement of ‘automotive emission regulations’ has not been included, nor is the

2 What is a ‘business’?
The legal issues involved in setting up and running a business can be complex and confusing, especially when some of the terms used don't seem to have clear meanings. This unit from the College of Law gives a basic introduction to the legal concepts of companies, partnerships, assets and liabilities.

Described as a ‘topic paper’, this 2007 document draws together a range of evidence on gender differences of pupils from the Reception Year to the Sixth Form, including current statistics, international performance data, as well as research reports.
This scheme of work has been developed in line with the recent introduction by the QCA of the ‘fourth pillar’ of Citizenship Education, which focuses on identity and diversity as a key concept underpinning Citizenship.

This unit 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, dispersion, and symmetry or skewness of a set of data, and for making comparisons of these features in two or more data sets. Boxplots can also be useful for drawing attention to possible outliers in a dat

This Teachers TV programme explores an approach to learning and teaching at one school which encourages pupils and staff to work together, with a view to developing their school’s transformation away from a ‘one size fits all’ curriculum. An important component of this is the introduction of the Royal Society of Arts (RSA) Opening Minds curriculum with Year 7.
You may have met complex numbers before, but not had experience in manipulating them. This unit gives an accessible introduction to complex numbers, which are very important in science and technology, as well as mathematics. The unit includes definitions, concepts and techniques which will be very helpful and interesting to a wide variety of people with a reasonable background in algebra and trigonometry.

This unit will help you to identify and use information in maths and statistics, whether for your work, study or personal purposes. Experiment with some of the key resources in this subject area, and learn about the skills which will enable you to plan searches for information, so you can find what you are looking for more easily. Discover the meaning of information quality, and learn how to evaluate the information you come across. You will also be introduced to the many different ways of organ
