Hello, is this planet Earth ? | Teach with space T03

In this activity, students will communicate with a rover on Mars. The objective of the mission is to send an automatic message from Earth to a rover located on Mars via an Orbiter. This message is sent by a programmed, LEGO-built, robot running an automatic switch. The rover on Mars receives the code via a LEGO light sensor, and students analyse and model the data to translate the message. Students learn how a basic telescope works by magnifying images of Mars using two lenses.

Learning objectives
  • Students will learn how to understand optical propagation of a light source 
  • To model a light ray
  • To verify the law of light reflection on a plane mirror 
  • To magnify an object with lenses: bi concave and bi convex 
  • To model data or processes to answer scientific questions
  • To develop scientific research experiments and engineering skills, for controlling individual experiment parameters
  • To collect data with a sensor 
  • To use a robotic tool to explore scientific content 
  • To work and communicate as a team
