Computers store drawings, photographs and other pictures using only numbers. The following activity demonstrates how they can do this. This resource includes ideas teachers can use to introduce the topic in order to develop understanding of image representation followed by two activities to be used as reinforcement...

A multiple choice quiz on colour by design for A/AS level chemistry.

Although it is written for OCR AS/A level chemistry (Salters) H033/H433 course, it can be edited to suit your scheme of work.

This activity, from the Institution of Engineering and technology (IET), introduces students to colour theory. Students look at products where the manufacturer makes a point of producing the same product in a range of colours, for example, mp3 players. They then...

This resource provides activities that link in which geography at primary level, using images of cities and Islands around the World taken from Space. These images taken by Tim Peake, support children in recognising human and natural features from an aerial view. They develop their understanding of maps and keys/...

A picture is shown of some 3D shapes. The shapes are to be painted subject to the constraint that adjacent faces must be painted different colours. The challenge is to find the minimum number of colours needed for each shape. This resource is suitable for Key Stage 3 and could be used as an extension when teaching...

This puzzle is ideaL when working on 2D representations of 3D space. The top, side and front view of a stack of blocks is shown. The challenge is to work out how many blocks of each colour are in the stack. This resource is suitable for Key Stage 3.

This activity, from the Association of Teachers of Mathematics (ATM) publication ‘It Makes You Think’, consists of a series of clue cards and a series of resource cards. The resource cards consist of different coloured discs. Students are required to arrange the discs in a specific order by following the...

Combinations consists of seven instant maths ideas including a consideration of the number of arrangements of dots used when writing in Braille, an investigation of Pascal’s triangle, investigating the number of routes through New York, exploring the number of ways six letters can incorrectly be placed in six...

This SMILE resource contains two packs of games, investigations, worksheets and practical activities supporting the teaching and learning of combined transformations, from drawing symmetrical patterns to using matrices to perform shears.

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Use observations to determine whether a substance is in solution.

• Recognise that a compound has properties (including solubility) that are distinct from its...

In these activities, pupils are introduced to the idea of controlled or uncontrolled re-entry for satellites. They are challenged to devise a way of reducing space debris by designing alterations to satellites so that they bring themselves back to Earth. In the first activity, the students pretend to be satellites...

This unit of work enables students to understand the risks, costs and potential benefits in the commercial exploration of space; and why decisions about scientific and engineering solutions need to take account of expert opinions from a broad range of disciplines.  Initially students work...

This challenge looks at how many common factors greater than 1 are shared by numbers, with bars representing how many factors a pair of numbers have in common. There are three grids to complete with numbers from 1 to 20 to show this relationship. This resource is suitable for Key Stage 3.

A Year Ten module from the Salters’ double award science course. Exercises on codes and signalling methods introduce ideas about communication. A study of the ear leads to sound communication systems such as radio and telephones. Lenses are studied and the formation of...

This activity, from the Institution of Engineering and Technology (IET), introduces students to the necessity of developing standards and protocols for communication.

It is intended that students will be able to:...
