Variables Unplugged

This activity away from the computer is from the Barefoot Computing project. It is intended to provide a theoretical understanding of why and how variables are used in computer programming, using the example of score-keeping in a classroom quiz. Involving several volunteers from the group, the activity uses...

Scratch Maths Quiz Variables

This Barefoot Computing resource builds on the ‘Maths quiz with selection’ learning activities which should be undertaken first.

It involves improving an existing Scratch maths quiz and adding score-keeping using variables – a quiz Scratch file is provided for students who do not have access to one they made...

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.

Seeing Temperatures

This activity allows students to investigate how images are produced from data streams by using first a spreadsheet and then an image-processing program. They then go on to see how the usefulness of such a monochromatic image may be enhanced by using lookup tables and calibration. The materials used focus on the...

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...

Building Images

In this activity, students create colour images from satellite data. This allows them to study how different surfaces reflect different wavelengths of light, how coloured images are created using an RGB model, and how band combinations can be chosen to examine a particular landscape effectively.
