Straight Lines

This interactive file deals with...

This interactive excel program is about finding the equation of straight lines in the form ax+by+c=0. The first two sheets deals with the equation of the line through two given points and the equation of the line through a point perpendicular to a given line. The...

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...

This file deals with simplifying, squaring, adding and subtracting numbers expressed in surd form. It also includes rationalising the denominator.

The file begins with a table showing the squares and square roots of...

This excel file explores the relationship between tangents and normals.

In the first interactive sheet the user can alter the coefficients of a quadratic function and see how this affects the graph and equation of...

This interactive file deals with various angles and lengths within tetrahedrons.

The first sheet shows the diagram of a regular tetrahedron. Various sides and angles need to be calculated using Pythagoras Theorem and...

This interactive resource, produced by the University of Leicester, is designed to enable students to explore transformations of functions including translations, stretches, reflection in the axes and rotations.

The first activity uses function notation to explore translations parallel to the x axis and...

This interactive resource, produced by the University of Leicester, is designed to enable students to explore transformations of shapes including translation by a vector, stretches, rotations around a point, reflection in the axes and reflections in the lines y=x and y=-x.

The first activity draws a...

This interactive excel program covers distance/time and velocity/time graphs.

The first interactive sheet shows a distance/time graph made of line segments and some questions relating to speed for each segment and the...
