Histogram reconstruction is an activity designed to enable students to gain a deeper understanding of frequency density and how it is used in the construction of a histogram.

Students cut out bars from a rectangle with which students construct three histograms using the clues given in three partially...

This resource, aimed at lower ability Key Stage 4 students, introduces the concept of data compression, specifically Run Length Encoding. Students are asked to use an online tool to convert names into binary (ASCII), this binary data is then subjected to Run Length Encoding and encoded binary compared to the...

Using a spreadsheet as a grid of 'pixels', this computing activity teachers how 1's and 0's can store image data. The classroom exercises use images with increasing pixel resolution, looking at how this affects the clarity of the image. Moving from black-and-white images, the students then use grids of colour...

In this resource, the students are asked to look at various aspects of data security. In part this covers cyber security but it also looks at data integrity and ensuring that users data does not become corrupt through various means. There are a variety of activities provided, and all of the necessary resources are...

This lesson consists of a presentation on Data Representation, looking at how binary numbers work (and concludes with an exercise in converting binary numbers to denary). Students consider primitive monitors with q bit colour depth, represented characters and other data. before investigating how coloured images are...

This resource consists of 2 A3 Active Learning worksheets which could be used to either introduce and record information about data representation, or as a revision tool. There are plenty of activities across the two pages that would allow students to either recap work they have previously covered or to research...

This resource contains a number of activities and worksheets to support the topic of binary numbers. The content looks first at binary numbers, how they represent denary numbers, converting between the two, binary addition and using two's complement to represent negative numbers and thus perform subtraction. These...

Two topics that support the database topic are covered in this presentation. The emphasis at A level is investigating the technical architecture rather than application. These are two important topics often tricky to find resources for. 

This Core Maths resource looks at the recently developed technique of rehydroxylation for dating ceramic objects using an exponential growth model. The resource allows students the opportunity to apply their knowledge of growth and decay, along with logarithms, to a genuine scientific process.

This report from Ofsted looks at the provision for excluded pupils. Schools and local authorities are required to provide full-time and suitable education for pupils from day six of fixed-period and permanent exclusions. This survey evaluates the extent to which a sample of schools and local authorities were...

This collection of resources includes activities, investigations and articles to explore the concept of sound and hearing.

Pupils investigate the range of human hearing, explore the pitch and frequency of sounds and calculate the wavelength of sounds, they also discover the causes, effects and preventative...

Students who play with objects, listen to music or find other...
