Lab Name Introduction to waves, properties of waves, using experiment allowing the visualization of a computer generated and transmitted wave signal.
Subject Area Science
Grade 8
Topic Waves
Experiment Title Visualization of computer generated wave signal showing the frequency and amplitude.
Hardware Local experiment
The experiment require the following components of the 'COSMOS Education Toolkit':
  • Computer Node
  • Mobile Node
  • 2 x ADALM Pluto SDR

Remote experiment
The teacher and the students require to make a reservation in COSMOS testbed. They should follow the steps decribed in this link
Software
  • GNU Radio
  • COSMOS Educational Framework
Number of Sessions to teach the topic 1 - 2 sessions
Educational standards to be addressed
  • MS-PS4-1
    Develop a model and use mathematical representations to describe waves that include frequency, wavelength, and how the amplitude of a wave is related to the energy in a wave.
COSMOS concepts to be used for the lab Wireless signals, detection of a generated wave signal, signal strength, relationship between signal strength and amplitude.
K12 Educational Goals (How the educational goals are achieved through teaching using the experiment, how the topic is connected to the COSMOS concepts used) Teaching waves and the properties of waves by visualizing a computer generated wave signal on the computer screen and observing the relationship between signal strength and amplitude.
Short Description and Walk-through of the experiment Local experiment
  1. Teacher will use a short slide-show to introduce & explain the topic of waves, the different types of waves & the properties of waves.
  2. Materials & equipment are set up on student’s desks.
  3. Activity:
    • Teacher will transmit a wave signal from his computer using the ADALM-PLUTO Transceiver and the students will see if they can capture (receive) the signal and visualize it on their computer.
  4. Students will then determine the frequency and power of the wave signal that was sent.
  5. After all students complete their handouts there will be a share out with observations and comments.
