This session introduces you to converting denary or base 10 numbers to binary digits and back again. It consists of two files, a set of slides explaining how binary conversions work and a worksheet.

1. Read the slides in Slides - Binary Digits about binary digits. Make sure you are clear on how the values...

This is a short session looking at the structure of pixels in a digital image. It will help you understand how the number of bits used per pixel determines the number of colours that are available.

1. Open the Information document and read through the information about digital images. Look at how using...

This session explains how sound is converted from a continuous analogue sound that we hear in the real world and converts it into a digital format of 1s and 0s that can be used and played back by a computer. The session has a set of slides to read through and a worksheet.

1. Read slides 1 and 2 . This...

This session looks at how images and sound use compression to reduce their size when storing them or transferring them over the Internet or on devices to save space. In the session you will have a look at how an algorithm can be used to compress this data.

All the answers are to be written in the workbook....

The purpose of session 6 is to introduce you to how computers detect errors in data and where the error occurs. It will introduce you to the idea of parity bits and parity check to determine if the data has been corrupted. This session requires the use of a pack of cards or cards with a colour on one side.

This resource contains the second session of the Active Approaches to Level Three Applied Science, produced by the Science Learning Centres and the Nuffield Foundation, and concentrates on the issues of health and safety and risk assessments. The session identifies suitable practicals and includes activities.

This activity helps learners begin to consider some issues involved in setting up their own business by making an initial, outline, mathematical model of the costs involved in setting up a business. Learners are required to work in small groups to create a poster showing the factors they would take into account,...

The human population of Earth has reached seven billion. This Catalyst article explores the impact that human activity may have on the planet. The article looks at the rate of population growth and how human impact is also related on the amount of resources used by an individual. It considers if the effects of...

This video shows how cards with different shaped holes circle, square, triangle), held to the sun, produce circular points of light, because what is seen is the image of the sun (this is how a pinhole camera works).

This collection of Nuffield Maths resources explores Shape and Space. The demand is roughly equivalent to that in Higher Level GCSE and Level 2 Functional Mathematics. 

In this Core Maths activity student pairs are asked to identify the force on the foundations of twelve iconic buildings. Both the volume and surface area of the buildings need to be calculated, with appropriate estimations made. Students are then asked to place the buildings in order of foundation...
