Apply amplitude, wavelength, and coding concepts together in a hands-on review investigation.
This unit connected several big ideas: waves carry energy and repeating patterns; amplitude and wavelength describe a wave's size and spacing; sound and light are two different kinds of waves; and patterns in a wave can be turned into a code that carries information. This week's lab pulls all of it together in one investigation.
You will make and measure a real wave, connect its amplitude and wavelength to what you would hear or see, and then use that same wave, sound or light, to send a short coded message, exactly as you have practiced separately in earlier weeks. Doing it all in one sitting is how you prove the ideas actually fit together.
Mastery looks like: They can measure a wave's amplitude and wavelength, connect wave properties to sound or light, and use a code to send and receive real information across a distance.
Common stumbles: Treating amplitude, wavelength, and coding as three separate unrelated topics rather than connected pieces of how waves carry energy and information.
