This longer-duration activity involves prototyping a low-power lighting system. It could be used in an off-timetable workshop or across a series of lessons.

Students are challenged to work through the whole design process, and to place a micro-controller (in this case a BBC micro:bit) at the centre of the...

The BBC micro:bit is a great tool for carrying out surveys that involve quickly counting and recording one or two variables. Using the button inputs provides a simple interface to the device allowing, for instance, quick tallying of the numbers of two different types of bee around a plant. Other examples might...

This activity, suitable for a multi-lesson sequence or a single extended session, challenges students to design and prototype a simple motion-sensing alarm. The device is intended to prevent theft or the accidental picking-up of a bag.

Motion is sensed using the accelerometer built-in to the BBC micro:bit,...

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.

Programmers can program computers to learn to do certain tasks.  Although the programmer writes the initial program, as it is fed more data the computer changes the way that it carries out the task in order to improve its ability to perform it.  However, ...

After learning about flooding, students consider the design problems caused by its early detection. Students are introduced to moisture sensors, and can build their own using the instructions provided or use a ready-made version. This is connected to the BBC micro:bit and used as an input device. After processing...

This activity booklet uses the real life context of air traffic control using radar signals to identify the position of an aeroplane that students act out. It provides them with an opportunity to use their knowledge of waves and speed = distance / time to calibrate and calculate the distance a plane is from the...

Artificial intelligence (AI) is a disruptive technology, meaning that it is significantly changing the way that people, businesses, and industry interact. To put it in context, the invention of the wheel, electricity, TV, and GPS are all disruptive technologies that changed the way in which society worked.

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...

The joy and challenge of building ‘cheap and cheerful’ sensors has a wide appeal to adults as well as children. It also opens a wide number of links to aspects of the mathematics, science, computing, design and technology, and engineering curricula, supporting scientific investigation and discovery. These...

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...
