Go over the test. Discuss the questions missed by high percentage of the students.
Test Remediation. Answer the questions that are correlated with the questions you missed on the test. This is due tomorrow.
When you have finished the test remediation, please read chapter 9 in the textbook. We will begin our discussion of the material tomorrow. Be sure to read and take notes on the chapter. It will help your understanding and of the material and will also make note taking in class a great deal easier.

-Where do our energy sources come from?
-How are they made?
-How much does each cost us?
-How long can we continue to use them?
Lastly, please do the questions on pages 263 and 276.

2. What frequency range can the average human hear?
Go over the dopple effect problems. Grab a whiteboard.
Discuss resonance.
Speed of Sound lab. For the lab you will work in groups of two. Each group will get two tuning forks. We will take turns using the resonance tubes to take data measurements. Please take your measurement, then step aside and do the calculations for the speed.
