Students are introduced to the terms "signal" and "noise" in the context of spacecraft communication. They explore these concepts by listening to a computer-generated signal from two different distances with no additional background noise, and then with background noise. They compare their experiences in a science journal page.

By the end of this lesson, students will be able to:

  • Understand the terms "signal" and "noise" in the context of spacecraft communications.
  • Compare the apparent volume of a signal at different distances from the source.
  • Compare the apparent volume of a signal at different distances from the source with the addition of background noise.
