Lesson plan
Before starting this unit, check that the children can recall:
Data transmission is the movement of data from one point to another.
The Mars rover is a robotic vehicle that explores, investigates and returns data about the terrain on Mars.
Binary is the the language used for communication between computers, including the Mars rover.
ASCII (American Standard Code for Information Interchange) uses binary codes to represent other characters, such as numbers and letters.
A computer's RAM (Random Access Memory) stores the instructions while a program is running.
A CPU (Central Processing Unit) is the computer's brain and handles data from input and output devices and the programs running on the computer.

Richard is a Year 6 Teacher at St. Pancras Primary School. Richard’s passion for teaching was recognised when he received Suffolk’s ‘Raising The Bar’ award for Innovation 2016. With his class he made the world’s first guided VR:360 school tour and also a 3D-printed asthma inhaler that Tim Peake tweeted about whilst he was aboard the ISS which led to a meeting back on Earth. His love of robotics saw him coach a rookie robotics team to win the UK finals of RoboCup where they then went onto the world finals in Brazil.
Richard’s Key Stage 2 lesson on building a smart school finishes our topic on ‘Big Data’ encouraging pupils to consider the advantages and disadvantages of using technology.
