HW Tuesday night/Wednesday night

Galileos and Einsteins: Tuesday night
Newtons: Wednesday night

(Due on Thursday for all)

Complex circuits and power practice.  I will post the steps in the folder to review how to solve complex circuits.

Reminder that the quarter closes Thursday and all work must be turned in!

Circuits test on Tuesday April 7th.

End of Q3 and Monday night HW

Updated grades are in Aspen- many of you are missing work and there are only a few days left until the quarter closes!

Please check your folders and make sure that you have all your assignments completed and turned in.

If you have any questions please ask me in class, by email or during X block.

Monday night HW:
Parallel Circuit Practice in the Electric Current folder.

TEST on circuits will be on Tuesday April 7th.  This will include a practical where you must build a circuit and use a multimeter.  You may come during X block for extra practice if you like.

By Monday morning...

As some of you know already, I will be taking a personal day on Thursday.  For the next few nights AND during class on Thursday you should work on the following assignments.  You can do them in any order you want; they just need to be done by Monday morning.

Newtons Tuesday night should do V = IR practice (see previous blog post)

1. Complete the graphs, slope calculations and questions for the Ohm's Law lab (document title is V vs I graphing).
2.  Complete "Graphing Practice for Current."  Remember to properly label axes, use consistent scales, calculate slope.
3. Complete "Series Circuits Problems."  Remember the chart!  The chart is FAIL-SAFE if you check your work!
4. AND....complete "More Series Circuits Problems."  Lots of practice!!

Galileos- I will see you next on Monday.

Einsteins- I will see you Tuesday afternoon, then again on Monday.

Newtons- I won't miss any class time with you- we have lots of time together coming up! Tuesday, Wednesday and Friday.  But you should still have all this done by Monday (we might be able to spend some time on Friday working on this).

If you get all this done and you are looking for something to do:

Check Aspen to make sure you have everything turned in.  All the columns with assignments are posted, even if the grades aren't.  You should make sure that for every column heading in Apsen you have that assignment turned in to your folder.

HW Monday/Tuesday night

Remember, a weird schedule is coming up because of MCAS.

Monday night HW for Galileos and Einsteins: V=IR practice.  Newtons will do this Tuesday night.

Weekend HW- March 20th

Happy Spring!

HW for the weekend: Basic Ohm's Laws problems in the Electric Current folder.  Don't forget units!!

Circuits Day 2 HW

Galileos and Einsteins- Wednesday night; Newtons- Thursday night

Please read on The Physics Classroom, Current Electricity, Lesson 2 "Requirements of a Circuit," also here.  In your notes answer the following questions:

1.  Explain how having a closed loop is requirement of a circuit.  How is this similar to water flowing in a pipe?



2.  Explain how having an energy source is a requirement of a circuit.  What is the analogous component in a water park ride?

HW after electrostatics quiz

Read the following section in The Physics Classroom:

Physics Tutorial: Current Electricity: Lesson 2: What is an Electric Circuit?  Also here.

Questions to answer while reading:

How is electric potential similar to gravitational potential?  Hint: imagine the charges "falling" from the top plate to the bottom plate.

Why would charge flow more easily through the "charge pipe" (wire) than through air?

To keep current flowing, what must happen to the charges once they "fall" down to the negative plate?

Define an electric circuit.

Electrostatics Test on Tuesday

Study guide is in the folder.  Answer key will be posted Monday morning.

Anyway who wants an opportunity to do test corrections later MUST have a completed study guide turned in to his or her Drive folder on Monday morning at 7:45.

Wednesday night HW

Electrostatics study guide- in the folder.  Answer key will be posted Sunday or Monday.  Test for all sections on Tuesday.

Coulomb's Law HW

Galileos and Einsteins- Monday night, Newtons Tuesday night HW:  Complete the Coulomb's Law practice problems in the Electrostatics folder.  Be sure to write out each problem before solving.

Weekend HW March 6th

In Ch 32 Electrostatics (in the Electrostatics folder), read section 32.3 (pp 504-507) about Coulomb's Law.  This should look very familiar to you!  Then answer questions 11-15 from the end of the chapter.

Information for while I am out, Thursday March 5th (Newtons only)

Today you will do the Electrostatics Pie Plate lab.  It is in the electrostatics folder.

Work with the person you sit with.  Each pair should have a piece of fur (in place of the wool), styrofoam plate, and pie plate with cup and pith ball (bit of foil).  Using your notes on the skunk analogy and the types of charging, explain each of the steps as instructed in the lab.


If you finish, go here, then click on the orange "run in HTML5."  Charge the balloons and sweater by friction, then see if you can figure out why they stick to the wall.

HW: read and notes on CH 32 (in the folder) pages 508-514.

Tuesday night HW

HW tonight for all sections: complete the "HW friction and contact" sheet.  Use your notes and CH 32 (sections on insulators and conductors, charing and friction) if you need other resources.
