Lesson 6 - Searching the internet
This activity develops digital literacy using the context of exploring Mars. Children learn about what a search engine does and consider what happens when they use one. They also begin to find out that some internet sources are more reliable than others and think about which might be trustworthy.
The...
Lesson 5 - Decision trees
In this activity children are introduced to decision trees and their use in computing algorithms. Working together they consider how a decision tree might support the navigation of the ExoMars rover searching for a suitable place to drill. They then role-play the rover and follow the decision tree instructions,...
Lesson 4 - Communicating images
In this activity children explore how images are stored and communicated by computers (including robots and rovers). They learn how a picture is made up of pixels and how each pixel is coded for by a number code, which is then converted into an image. Children learn about Binary code and how it is used to represent...
Lesson 3 - Flow charts and decisions
In this activity children use and create flow charts and are introduced to the idea of loops to repeat instructions. The activity uses the context of Mars exploration, with children using their instructions to help guide the ExoMars rover across the surface of Mars.
This activity has been provided by ESERO-...
Lesson 2 - Creating and debugging algorithms
In this activity children create an algorithm or a sequence of instructions. They test and debug their algorithms and refine them to improve how well they work. Working together they play a game, instructing the ExoMars rover, Rosalind Franklin, to reach the drilling station, avoiding crashing into other rovers....
Lesson 1 - What is an algorithm
In this activity children learn what an algorithm is and explore what makes good instructions for an algorithm. They work as a team to create their own algorithms to guide each other across a grid of squares avoiding set obstacles. The activity uses the context of Mars exploration, as they role-play the ExoMars...
This collection of activities provides a series of lessons linked to computing using the context of Mars exploration. Children learn about algorithms, debugging, flow charts, repeat loops, decision trees, and how images and data are relayed. They find out about search engines, the reliability of information found...
Roving with Rosalind is...
Understanding Satellite Images
This is a suite of six units of work developed for progressive exploration of digital images and satellite data. The first three units provide an introduction to the fundamentals of manipulating digital images. In the latter three units students apply this foundation knowledge to process and analyse satellite...
