Unit Goals:What is a wave? How do they act? How are do waves differ?
Goals: SWBAT...
1. Discuss waves’ properties using common vocabulary and they will be able to predict the behavior of waves through varying medium and at reflective endpoints
Warm-Up (5min):
1. Copy the image of the wave from the board.
2. Define the term, "wave"
3. Write a list of characteristics that you could use to describe the physical qualities of a wave. Describe each characteristic in words that any person could understand. Leave some writing space for characteristics that you might think of later during the activity

3. #058C: Waves on a String
We will be using an exciting new simulation, called PhET. Here's an intro to PhET: https://phet.colorado.edu/en/about
Directions:
1. Open Waves on a String, investigate wave behavior using the simulation for four minutes.

As you look at the waves’ behavior, talk with your groupmates about some reasons the waves might act the way they do.
2. Consider the list of characteristics you wrote in the warm-up. Do you see any of those characteristics present in the sim?
3. With the Oscillate button on and with No End checked, investigate waves more carefully using the Amplitude slider.
Write answers to the following after your group has talked about each and agreed.
a) Define Amplitude in everyday language.
b) Explain how the wave behaves as the Amplitude changes using the characteristics you described in the warm-up
c) Use a rope/string/ on the floor for some investigations and explain how you could change the Amplitude of a wave.
At Home Learning (HW)
1. Complete #058C part 3 (Oscillate) a, b, & c.
2. Tomorrow, I'll also be checking warm-ups (Day 49-56) for those who didn't show them to me on Friday, and the weekend video homework from Day 57.
