WAVES UNIT:
Cell Technology
“How are you hearing me?” asks a cell phone caller.
Over the course of the unit, you will discover the patterns with waves. Then, you will use that understanding to explain ultrasound medical imaging technology and ultimately how cell phones work. Cell phone communication is operationalized by the engineering challenge of communicating a three letter signal by first coding a spreadsheet to digitize the signal in binary (ASCII), then transmit the digital signal using light and sound (AM and FM), then receive and decode the signal to complete the communication. This project models the sending and receiving of a text message.

Unit 5 Learning Targets:
-
I can compare and contrast the general parts and properties of mechanical and electromagnetic waves.
-
I can collect data on wave speed, frequency, and wavelength and use it to build an understanding for how waves behave.
-
I can read and use informational texts about waves to answer relevant questions.
-
I can describe how instruments transmit and detect waves (i.e. cell phone and sonar).
Online Activities and Resources
Our class incorporates several online activities. To view these in HTML, visit the links below.
The Patterns Approach Physics resources were created through collaboration with industry members, higher education representatives, high school science teachers, and middle school science teachers. The resources include labs and activities that cover the Next Generation Science Standards (NGSS) for high school earth, life, and physical science AND incorporate engineering practices. The Common Core State Standards (CCSS) for Science and Technical Subjects have also been incorporated.
