This activity shows how to accomplish a simple, but nevertheless seemingly impossible task -making a fair random choice by flipping a coin, between two people who don’t necessarily trust each other, and are connected only by a telephone. The resource begins with a detailed explanation of the activity and...

Many optimization problems involve situations where certain events cannot occur at the same time, or where certain members of a set of objects cannot be adjacent. For example, anyone who has tried to time-table classes or meetings will have encountered the problem of satisfying the constraints on all the people...

Many real-life situations can be modelled in the form of a network or “graph” of the kind used for colouring in the Poor Cartographer – Graph ...

Using sparkles to code flashing sequences. There are variations on difficulty including the introduction of switches.

The students’ goal in this resource is to find Treasure Island. Friendly pirate ships sail along a fixed set of routes between the islands in this part of the world, offering rides to travellers. Each island has two departing ships, A and B, which students can choose to travel on in order to find the best route to...

This resource asks the question ‘How much information is there in a thousand page book?’ It continues by exploring how to estimate how much space is needed to store the information and introduces a way of measuring information content. The resource begins by discussing what is meant by information and how amounts...

This sample of a teacher guide introduces basic robotics using VEX IQ robotics kits and ModKit programming software – the activities are based upon a single robot model which can be constructed from the VEX starter kit.

Students learn about basic movement of the robot rover, as well as related challenges, in...

In this activity, learners will use a vacuum former to manufacture a suitable casing for a programmable product. It...

This brief activity uses false-colour images of the Columbia glacier to introduce the idea of using sequences of satellite images to monitor change and focuses on the selection of appropriate data for an investigation.

This short activity introduces students to the ideas of the footprint and resolution of an image, asking them to choose and use appropriate methods to calculate how these quantities would change as they moved a camera to a series of vantage points above the surface of the Earth

In this activity, learners will self-assess and plan how to extend their current knowledge of programmable systems.

This activity is designed to introduce students to what is meant by a program. It asks students to create a set of instructions that will solve a problem...

In this activity students take on the role of Earth observation scientists submitting a request for an image they would like for their research. This gives them the opportunity to consider the possibilities of pictures taken from orbit (and the limitations) and to write scientifically for a specific audience. It...

This engineering activity, suitable for children in computing lessons, looks at the basics of flowchart construction. Simple examples, such as the decisions made by a dog chasing a stick, are used to make flowchart representation of algorithms accessible to younger children. A simple design activity requires...
