Dijkstra's Algorithm

Dijkstra's algorithm finds the shortest path for a given problem. Dijkstra's algorithm can be used to find the shortest route between two cities. This algorithm is so powerful that it not only finds the shortest path from a chosen source to a given destination, it also finds all of the shortest paths from the...

The First Programmable System

In this activity students explore why a water clock was the world's first programmable system. Programmable systems are by no means a modern invention. Many regard the first to be Ktesibios's water clock, which was invented approximately 2250 years ago.

The aim of this activity is that students apply what...

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...
