A CS Unplugged series resource aimed at younger students but also works well with A level students. This illustrates the concept of minimal spanning trees and graph traversal.

The aim of a minimum spanning tree is to connect every vertex of the network using the edges having the least possible total weight. The task requires students to analyse information about a town centre and suggest which roads should be pedestrianized. [

This resource is part of a collection of Nuffield Maths resources exploring Algebra. The demand is roughly equivalent to that in GCE A level.

This resource asks students to use graphical methods to solve maximum and minimum problems in industry and in working life, using a spreadsheet or graphic calculator...

This Nuffield Working with Science unit was designed to develop simple skills of mineral testing and identification and a broad view of the subject of mining and minerals.

Guidance for teachers and technicians appears...

Read the letter from Nick Gibb MP and Jo Johnson MP that launched the Core Maths qualifications in September 2015.

From the National Non-Food Crops Centre, this factsheet looks at miscanthus, which has been grown in the UK for a number of years as an energy crop. The harvested material can currently be used to generate heat and power and in the future may be used as a feedstock for advanced biofuels. The factsheet looks at the...

From the Technology Enhancement Programme (TEP), these circuits allow students to build a range of devices. Each circuit has a full circuit diagram, component list and explanation of how the circuit works. In this section, the circuits cover a range of miscellaneous...

This video explains why objects of different masses fall at the same rate towards the ground. 

A heavy medicine ball is dropped at the same time and from the same height as a lighter basket ball.  They both hit the ground at the same time.

Although the medicine ball has a greater force on it, its...

This video shows the types of common misconceptions people have about heat.  A book and a metal object, that are the same temperature, are held by people.  They all say the metal object is colder. Using an IR thermometer, it is proved that a cake and its metal container are the same temperature as they are removed...

This video considers the misconceptions people have about heat. Most people believe that something that feels hotter to the hand must be at a higher temperature. However, this is not always the case. We do not feel temperature, rather we feel the rate at which heat is conducted towards or away from our hands. Two...

This video introduces the Hubble sphere and how the rate of expansion of space can be used to explain how we see very distant objects that are travelling faster than light. The limitation to the observable universe is the particle horizon (where the time is too great for light to have reached the Hubble horizon)....
