Weeks 7-9 Waves and Technology part 2.

Students wrap up the waves and technology unit right before spring break.  The unit test covers the four goals below and the 4 goals from the last cycle.  Their binders are also due right before spring break.
The engineering task that we finish this unit with is a little less involved than the last several ones.  They will code a spreadsheet with conditional formatting so that the inputs produce a gray scale image similar to an ultrasound.

Goals:

1. Give examples of why human’s understanding of light has gone back and forth between particle, wave and dual models.
2. Explain how information is encoded in FM and AM waves.
3. Calculate the depth of an object in an ultrasound.
4. Explain the physics of an ultrasound.
