Physical Science B
Bellwork:
None for today.
Get into your groups and continue to work on and finish the circuit lab.
You should finish the lab on circuits by the end of the hour. I will check your ohm's law problems during class today. We will check them and go over the answers tomorrow.
HW: Finish the lab questions. I will collect it tomorrow.
We are planning on having our test on Wed. next week.
Physics
Let's go over the test. Discuss the results.
Take out the homework problems 15-26. I will check and we will go over any difficult questions.
Observe the set up in class, then make observations about simple harmonic motion.
Q's:
1. What is simple harmonic motion?
2. How does this set-up demonstrate simple harmonic motion?
3. Why in the world are we making a set-up that has a mass on a spring, when the chapter is about waves? What is the point or more importantly, what is the connection between simple harmonic motion and waves?
Discuss simple harmonic motion and wave characteristics.
HW: Simple harmonic motion packet.

Physical Science B(Wed.)
Bellwork:
1. Explain the difference between a series circuit and a parallel circuit
2. What happens to the resistance within a parallel circuit when items are added? What happens if they are added in series?
3. Consider a situation where the three items where hooked up in a circuit but you had no knowledge of how they were connected. If you tested and found that the voltage at each device was the same, what type of circuit would it be? If you instead found that the current was the same for each device, what type of circuit would that show we had? What methods could you also employ to determine what type of circuit was present?
Objectives:
1. Understand and explain the difference between series and parallel circuits.
Check and go over the circuit diagrams. Use the whiteboards. Discuss the results.
Hand out and explain the simple circuit labs. You will be assigned to groups.
HW: Pick-up and work on the Ohm's law problems.
Physics (Wed.)
No Bellwork Today.
Test over electricity.
When you have finished, please read chapter 14, take notes on the chapter. Please answer the questions on page 386 (q's 15-26).
We are going to begin our discussion of waves, sound, and light.

Review what was discussed prior to break.
Discuss voltage, current, and resistance.
Handout and discuss Ohm's Law problems.
HW: Ohm's Law problems. Also, we will hand out and begin the home energy audit. We will explain this process and how you will begin.
Physics B(Monday)
Welcome Back! Seniors you are on your downhill stretch now!
Today we are going to review all the material from before break and we will go over all the math problems.
We will do group problems. I have assigned groups:) Nice try guys.
Each group will have a set of problems that they are going to work on. Then they will be responsible for going back to their secondary groups to teach the process to the other members of the group. At the end we will summarize and wrap-up. Secondly, each group will be assigned a set of problems from the homework over break.
Tomorrow, we will have a practice test.....we need to get your minds back into the swing of things!
The test will be on Wed.
