This interactive excel file shows how the volume of a prism relates to the area of cross section and the length. Various different shapes of cross section are used including pentagons, hexagons, circles and semicircles. In each interactive sheet the cross section can be...

The texts for Revised Nuffield Biology offered an amended version of the fifth year of the five-year course to O-level. The revision was based on the experience of numerous teachers with the original edition. Extra help in the teachers’ guide included: *indications...

This activity, from the Institution of Engineering and Technology (IET), introduces students to a mathematical solution to code breaking by using a simple substitution code. Students will make a survey using the frequency of letters in English sentences, match up an...

This problem involves using vectors to model 3D space. Two skew lines are presented and the challenge is to find the shortest distance between the lines. In addition, the...

This activity introduces children to simulations - modelling or acting out real-world, or maybe imaginary, situations. Linking to the teaching of space, it asks what factors need to be considered when simulating the solar system. Out of these, the children then decide what the most important things to include in...

This video looks at the structural design of the O² building in Dublin. This is a built music venue with a capacity of 14,000 people, designed to provide unrestricted views and excellent acoustics. The film shows the exciting role of acoustic engineers and explains how they developed criteria from the...

This activity, from the Institution of Engineering and Technology (IET), allows students to investigate the velocity of sound. Two methods, a direct method and an ICT based method, are proposed.

The activity is part...

This activity, from the Institution of Engineering and Technology (IET), gives students the opportunity to develop their understanding of graphs in an engineering context. Students learn about dance floors that generate electricity and consider how output is linked to...

The first video explores the first computers that had stored programs in the same memory space as the data required for them.  This is known as the von Neumann architecture and is still the foundation principle on which most computers are still built today.  We take the lid off a central processing unit and explain...
