### Vectors 2

The first two sheets use maps of New York to show how vectors can be used to specify journeys. Answers in terms of a and b can be revealed.

The third sheet shows that the vectors a and b used to describe relative position do not need to be perpendicular or equal in magnitude. It also illustrates parallel...

### Vectors

This interactive excel sheet deals with a variety of vector topics. It begins with sheets which require students to identify column vectors from line segments and then to find the magnitude and direction of vectors expressed in column form.

The next interactive sheets illustrate the fact that a+nb lies...

In this DfE Standards Unit resource, students identify different forms and properties
of quadratic functions, connect quadratic functions with their graphs and properties, including
intersections with axes, maxima and minima. Students will need to be familiar with the...

### Gas Compression and Expansion

This engineering resource, produced by Mathematics in Education and Industry (MEI) for the Royal Academy of Engineering, asks the question: how can you calculate the energy used, or made available, when the volume of a gas is changed? A bicycle pump, a refrigerator and the internal combustion engine change the...

### Horizontal Gene Transfer

This animation shows how bacteria exchange genes on small pieces of DNA called plasmids through a process called horizontal gene transfer.

Bacteria are able to exchange genes quickly within a population on small circles of DNA called plasmids. This animation shows how bacteria exchange plasmids through a...

### Wellcome Trust: Tree of life

Produced by the Wellcome Trust, these resources include an interactive evolutionary tree and a video of the Tree of Life. These materials will help students to find out more about the work of Charles Darwin and evolution. The resources contain:

Tree of life video: The video is a short...

### MRSA Animation

This animation from the Wellcome Trust Sanger Institute is suitable for GCSE and A-level students and provides an introduction to the bacteria Staphylococcus aureus.

The animation describes how drug resistant strains such as MRSA can be spread in hospital settings, how infections can be treated and how MRSA...

### How the Human Genome Was Sequenced

From the Wellcome Trust Sanger Institute, this resource introduces the Human Genome Project (HGP).

A short animation gives:

* an introduction to DNA and genomes;

* an overview of which countries were involved in the international Human Genome Project;

* a description of the processes,...

### Subcloning

This animation shows the major stages of subcloning. This is the process of breaking up fragments of DNA from BAC clones into smaller more manageable pieces for DNA sequencing. This process was very important during the Human Genome Project. Subcloning involves several standard molecular biology techniques...

### DNA Libraries: Bacterial Artificial Chromosome (BAC)

Produced by the Wellcome Trust Sanger Institute, this resource contains an overview of the techniques involved in making a BAC (Bacterial Artificial Chromosome) library. It consists of an animation that covers the key stages in the process:

* Extracting DNA from white blood cells and use of restriction...
