During this lesson, students will see the radio waves passing through their areas visualized on the screen in the classroom. Next, students will work in small groups to identify the broadcasters of these waves. Lastly, students will work independently to write a persuasive essay about how the spectrum should be shared among users.
HS-PS4.C Information Technologies and Instrumentation.
