Happy Monday. Your video lecture for today is here: https://youtu.be/gsu1C5ZYp7w
If you don't have all the materials at home, no problem. Try to get them so you can experience making sound and changing pitch. If you can't though, I have a video showing the whole process, and will post it here.
ESSENTIAL QUESTION: How do waves interact?
GOALS: SWBAT...
1. determine what causes the pitch to change
WARM-UP
1. what does high pitch sound like? low pitch?
2. would a high pitch sound have a high or low frequency?
3. Draw a longitudinal wave and a transverse wave.
4. Does sound travel as a longitudinal wave or transverse wave
5. If a compression from one wave interacts with a rarefaction from another wave, what kind of interference occurs? What would this sound like?

ESSENTIAL QUESTION: What are the characteristics of EM waves?
GOALS: swbat...
1. observe that light can only be seen when it bounces off an object
2. classify objects into the categories transparent and opaque according to how they interact with light
WARM-UP (4 minutes)
Just in case you missed this on Monday...
