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 resource consists of two interactive excel files dealing with some aspects of construction and geometric proof.

Perpendicular Bisectors...

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...

In this Nuffield resource rooms in a rectangular maze of rooms have bags with a varying number of gold coins. Students explore the effect of the route on the number of gold coins that can be collected.

The key processes involved in the activities are:

*Representing - identifying the mathematics...

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...

An interactive resource from the Association for Science Education (ASE) that introduces nutrition, and offers students the chance to have their say on healthy eating. Students research different nutrients and their sources, before making changes to a player's favourite...

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 interactive game from the Association for Science Education (ASE) tackling the interpretation of distance/time graphs in the context of a football match. Graph Shots is an interactive game that develops students' understanding of distance/time graphs. Students compare graphs with written accounts and video...

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...

Graphing Lines gives the opportunity for students to explore the parameters of a linear equation; how modifying the graph affects the equation and how modifying the equation affects the graph. Students can draw reference lines y=x and y=-x to help with their deliberations. Students may change the point of...

This simulation allows students to visualise the gravitational force that two objects exert on each other. It is possible to change properties of the objects in order to see how that changes the gravitational force between them.

The simulation can be used to:

*Relate gravitational force to the masses...

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 shows the processes of growth in plants at the cellular level. It demonstrates how growth occurs at specific regions within the plant, how cells divide by mitosis, and how cells become specialised into different tissues...
