In this resource the head of a circular snowman rolls around its circular body to make one trip back to where it started. The ratio of the diameters of the circles is given. The challenge is to find how many times the head will revolve throughout the journey, and find a general rule.

The resource contains a...

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, manufacturing engineer Greg Bowie is the inspiration for Emma Newman to write 'Healing the Fractured'.

Short audio clips about the...

This activity challenges students to design, and agree on an optimal route for, a village bypass, subject to the Highways Agency constraints for road design. Students use the provided software or physical resources and measure lengths of lines and curves, fine tune cost-benefit trade-offs, interpret data, convert...

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...

In this activity, students explore the miss-match between real and perceived risk by exploring the risks of dying unexpectedly from various causes. Starting from known fears and comparing them with real-life data, students can recognise that these fears are often unfounded. Students have the opportunity to learn...

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,...

Human Torch is a 'learning adventure', sponsored by the Health and Safety Executive and provided by the Association for Science Education (ASE).

The resource combines computer-based activities with video and experiments. Human Torch begins with a short dramatic video scene showing a victim who burned to...

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...

This program begins with graphs of the hyperbola in the form x²/a^...

This resource is based around the chemical composition of the human body and the origin of elements in the universe. Students can input a mass in the spreadsheet to see what proportion of their mass is from elements created in the Big Bang, in stars and in supernovae. Graphs are also shown for the relative...

In this activity students are asked to construct a simple mathematical model to help decide whether or not the umpire has made the correct decision. Students are required to revisit and test assumptions made in their initial model, make estimates of likely uncertainty and apply their model to similar situations....

This series of interactive excel sheets investigate models involving an inclined plane.

The first sheet helps students to investigate the conditions for movement of an object on a horizontal plane.

This resource contains two interactive excel files providing an introduction to indices, dealing with products and quotients involving indices and evaluating fractional indices (positive and negative). Each file contains the same further 16 sheets of questions which may...

This resource contains two excel programs with interactive spreadsheets dealing with linear inequalities in one or two variables.
