Physical Science B(Tuesday)
No Bellwork today!
Log on to your computers and get into examview
When you have finished, read chapter 7, sections two and three in the text over electricity. We will discuss electricity and its applications. Please answer the questions for the section 2 and 3 review at the end of each section(pgs. 205 and 213).
We will have a test remediation tomorrow.
Lastly, please hand in the review questions and the electrostatics lab. I will check these over break.
Physics B (Tuesday)
Bellwork:
1. A circuit is hooked up in such a way that the current is the same in each of the resistors. Resistor number one has a resistance of 6 ohms, the second has a resistance of 8 ohms, and the third has a resistance of 10 ohms. If the total voltage in the circuit is 24 volts, find the voltage and current in each of the devices. Secondly, find the total current and resistance for the circuit. Lastly, identify what type of circuit we are dealing with in this problem.
Collect the bookwork that was assigned over the weekend.
Finish the lab on resistance. This will be collected tomorrow.
I know that I had intended to have a test today, but we are not ready yet. We will continue this chapter through break and then test when we get back.
HW: Finish the summary questions over the resistance lab. If you have any issues, please stop in to see me.

Physical Science B(Monday)
Bellwork:
1. Is it feasible to transfer protons between objects to provide a positive charge?
2. What are three ways that charges can be transferred? Explain.
3. Based on the results of your lab, what happens when a charged object is brought near a neutral object? What would happen if the touched?
4. Why is plastic used as a coating on the outside of most residential electrical wires?
5. How does lightning occur?
Work with your table partner on the sheet that was on the stool by the door.
Finish the electrostatics lab.
Key Concepts to focus on:
-How to use a pith ball to determine if an object is charged.
-The difference between conductors and insulators.
-How to use an electroscope to determine the sign of a charge.
-How to charge by contact and by induction.
Go over and discuss the material. Wrap-up and discuss problem areas. Go over any difficult questions from the review sheets.
The lab will be handed in tomorrow before the test.
Practice test.
HW: Study for the test. Go over the vocabulary and major topics.
Physics B (Monday)
Bellwork:
1. How is the current affected by adding bulbs to a series circuit? Parallel? Is the same true for resistance?
2. What happens to the potential energy of a positive charge as it is move further from another positive test charge?
3. What has to be done in order to move a charge from a low potential to a higher potential?
Review major concepts.
Finish the series and parallel circuit lab.
We will wrap-up most of the material tomorrow.
HW: finish the summary questions for the lab.

Physical Science B
Bellwork:
1. Find the number of protons, neutrons, electrons for the following elements:
a. 30 Mg
18
b. 107 Ag
47
2. Whenever charges are moving for either an electrical discharge or flowing current, what type of charge is responsible?
Objective:
Be able to explain Coulomb's Law. Basically, explain how the force between charges relates to the size of the charge and distance between the charges.
Quiz: Atomic Number Quiz
Please take out your electric field homework. We will check and go over the homework on the whiteboards
When finished we will use the computer model to look at Coulomb's Law.
HW: Activity, computer air hockey. Use concepts of interacting charges and the forces between the charges to complete the activity.
Here is the link:
