This simulation allows students to pump gas molecules into a box and see what happens as you change the volume, add or remove heat, change gravity, and more. They can measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other.

This excel file allows students to explore the successive terms of a Geometric Series. The first term and the common ratio can be altered and the successive terms and sum of the series shown on bar charts. The formula for the sum of a Geometric Series is derived and the...

This series of interactive excel sheets help investigate geometric series and progressions.

The first sheet generates the terms of a geometric progression, for |r| ≥ 1, and the value of a further term. A new sequence...

This multimedia package was developed by the Gatsby Science Enhancement Programme to help students understand the interesting and unusual properties of a range of fluids, semi-solids and solids. Published originally as a CD-ROM, the materials contain a collection of...

This series of excel interactive sheets look at the golden ratio.

The first two sheets investigate the ratio of each pair of consecutive terms in the Fibonacci series, and what happens to the ratio as the sequence...

This excel program contains a series of interactive spread sheets designed to explore the concept of a gradient of a curve.

The first activity illustrates that the gradient of a function, at a point P, is the gradient...

This resource is an interactive excel program to enable students to investigate the solution of polynomial equations up to cubics using a graphical method.

The program shows the graphs of cubic equations and the...

This program allows students to solve pairs of equations by drawing 2 graphs and looking at the points of intersection. The graphs can be cubic, quadratic or linear. The 1st interactive sheet allows students to plot pairs of graphs by changing the coefficients of y=ax...

This resource is an interactive excel program to enable students to investigate exponential growth and decay. The topics of the interactive sheets are depreciation, exponential growth of bacteria and half life and radioactive decay.

This animation, from the Wellcome Trust, shows how the human immunodeficiency virus (HIV) infects white blood cells and uses its RNA to produce a strand of DNA which becomes integrated in the host cell's genome.

HIV...

This is a series of interactive excel sheets that look at histograms.

The first sheet contains a histogram displaying a summary of time spent travelling to work. A new set of data can be generated at the click of a...

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...

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,...

This resource is based on the Inventive podcast. The podcast mixes engineering fact with fiction. Each podcast features an interview with an engineer. In this activity, electronics design engineer Shrouk El-Attar is the inspiration for Tania Hershman to write 'Human Being as Circuit board, Human Being as Dictionary...
