Design a prototype step counter (stepometer)

In this challenge, students are asked to evaluate an existing product – a step counter or pedometer. They then create a step counter to encourage healthier lifestyles among teenagers. It is based on a BBC micro:bit device which includes an accelerometer capable of detecting ‘shake events’. These events are then...

World Map Logic Activity

This Barefoot Computing activity for lower primary children uses simple sequences of instructions to explore a world map. They use logical reasoning to predict the outcome of instructions that are 'programmed' into a simple game, made using Scratch 2. Children learn about the continents by guiding a simple robot...

Scratch art lesson - application of repeat function

Focusing on the programming skill of loops and repetition, this activity offers a chance for pupils to apply their understanding, linking both Scratch and art. With links to modelled examples, teachers could apply the PRIMM method to their lessons, through the pre-created Scratch projects.

Writing a Flowchart

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...

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...

Home energy

Reducing energy usage in the home saves money, increases energy security and reduces the need to burn unsustainable fossil fuels. The first step in doing this is monitoring how much energy is...

What is a program

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 and defines a program as a set of step by step instructions that must be followed.
