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...

A cross-curricular programming activity, using loops in Scratch to draw patterns. Learners first design an algorithm to draw a simple 2D shape, and then use the 'repeat' block to generate artwork. It is advised that children have some prior experience of programming in Scratch. Experimentation and debugging is...

This is one of a series of resources to support the use of the BBC micro:bit.

In this activity pupils will make use of the BBC micro:bit to design and create a programmable system that can control the temperature and soil moisture levels in a ‘smart’ greenhouse. They will analyse a design brief and design...

This activity introduces children to simulations - modelling or acting out real-world, or maybe imaginary, situations. Linking to the teaching of space, it asks what factors need to be considered when simulating the solar system. Out of these, the children then decide what the most important things to include in...

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...

This activity shows how Earth observation can be used to study human geography by comparing the satellite images of Las Vegas over the last few decades. Linking to measurement of irregular areas and addition and multiplication of fractions, it asks children to measure the area of Las Vegas at three separate times...

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 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...
