If students are broadcast, resume the SAT

In this lesson, students study how radio waves are used in communication systems and understand how they can be used in a CanSat project. First, however, they have to understand the most important properties of radio waves and their location in the electromagnetic spectrum. Then they find out what different types of radio waves there are and what different functions and uses they have. After acquiring the theory, the practical part comes at the end, in which the students use a radio module to receive data from their 'CanSat'. The lesson is also ideal as preparation for participating in the CanSat competition.

Objectives: The students learn ...

  • Understanding waves and the electromagnetic spectrum.
  • how modulation works and why it is necessary for the transmission of information.
  • the relationships between frequency, wavelength and radio wave propagation.
  • identify the elements necessary for a communication process.
  • distinguish between different communication protocols.
  • program their own radio modules.
  • Build your own antenna and use it to receive information.
