Earth-Moon Comms

In this activity, students will simulate communications between a base on the Moon and a base on Earth.
To do this, it will be divided into two Teams

  • Engineers at the Earth base.
  • Engineers at the base of the Moon.

 

Each team will use a micro:bit board and a different computer to program communications in blocks. Each micro:bit board (plate A and plate B) includes a short-range radio transmitter. The programming will be done on the free web platform MakeCode copying the instructions explained visually and simply in the guide to:

  1. Set up a channel (group), which will be the same
  2. Send messages ("radio send string") from the A board.
  3. Receive them ("when receiving radio chain") on the B-board and display them on the LED array or with a buzzer.

During the activity, the group designs a minimum protocol (e.g. using keywords or icons) and checks the actual range of the signal in the classroom.

RECOMMENDED AGE: 10–12 years
LOMLOE COMPETENCIES:

  • Competence in science, technology and engineering
  • Digital competence
  • Personal, social and learning to learn competence
  • Entrepreneurial competence

DIDACTIC OBJECTIVES:

  • Understand how two wireless devices communicate at short distances.
  • Schedule sending and receiving strings and icons with micro:bit radio.
  • Design a simple protocol and test its reliability.
  • Encourage cooperative work and reflection on clear communication.

MATERIALS (per team):

  • 2 x micro:bit boards (+ battery holders)
  • 2 USB cables for charging/encoding
  • Space in classroom or hallway to test range

INCLUSION:

  • Rotating roles (programmer, sender, receiver, recorder).
  • Messages also coded with icons for students with reading difficulties.
