In this activity, students will use the characteristics of waves to encode and send a Snapchat message to a classmate. They will then decode the message they received using their knowledge of frequency, wavelength and amplitude and transform the wave back into text.
This activity is a great way for students to learn about the way that messages are transmitted wirelessly across the air.
