The Scratch patch - substitution cipher

This project, exploring basic encryption, is a useful introduction to data security as well as iterating through strings to manipulate them. The program create a ‘substitution cipher’, one of the most basic forms of encryption. It also demonstrates that, for more complex chained commands, Scratch becomes rather...

The Scratch patch - error handling

This activity is an introduction to writing programs that can handle errors. It also helps students to understand number bases, by guiding them through the writing of a ‘base converter’ program.

Where Would You Photograph? (7-11)

In this activity children 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...

Where Would You Photograph? (11-14)

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...

Watching a Glacier (11-14)

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.

Exploring Rainforests

In this activity, students examine changes to forests in cross-border regions of Africa and Borneo using Google Earth Pro to help identify features shown in satellite images and make measurements. The context allows students to explore the factors which put pressure on forested areas, and what is being done to...

CS4FN Issue 8

This issue of Computer Science for Fun is entitled ‘Computer Science in Space’, and explores the role of computers in space exploration and astronomy.

It includes articles covering:

• Computer scientists working for NASA

• GPS and computer art projects that love your data

• Computers,...

Introduction to VEX Robotics

In this full scheme of work, designed for a series of two-hour double-lessons, students develop a Mars Rover for NASA based on a standard VEX design. They learn about the components of a robotics system including control units and data communications, and work through a design process towards a prototype. The VEX...

Introduction to computational thinking and the Internet of Things

This one-hour lesson examines the design of IoT algorithms, considering how individual devices execute algorithms as code, allowing them to work together. The key aims are to develop computational thinking while raising awareness of the potential for future careers and enterprise.

The lesson starts with the...

Heart Rate Monitor

In this challenge, students are asked to consider the impact of people suffering from heart conditions, both to the individual and to wider society. They then generate ideas for using programmable systems to improve people’s health, and to monitor themselves. A video introduces the idea of a heart rate monitor, and...
