Exam Review

Work on the "Final Exam Review" in the MCAS practice folder.  You should come in tomorrow with any questions that you have.

All work must be turned into your folder by the end of the school day on Monday, June 15th.

And finally, congratulations on being (almost) done!  Have a great summer!

-Mrs. Darlington

No homework!

No homework!!  Except to get a good night's sleep and eat a filling breakfast in the morning.

Remember to bring a pencil, calculator and book (or other non-electronic thing to do if you finish early).

Room assignments:
Galileos: A214
Newtons: A 203
Einsteins: A209

It will be fine.  And over soon.

MCAS review

Congratulations on being all done with learning new physics stuff!  We will spend a few days of review and practice for the MCAS next Tuesday and Wednesday.  Tonight do the 2012 MCAS, posted in the MCAS review folder.

Please Note: There is an error in the BHS planner.  MCAS will be on Tuesday and Wednesday, NOT Monday.  The schedule will remain as is in the planner with a Monday morning X block.

Quiz on Heat Wed all sections

Quiz for all sections on Wednesday.  By then, you should complete "Q=mcdeltaT joules" problems, "more q=mcdeltaT problems," and the Heat Study Guide.

UPDATE: Answer Key to study guide posted in Heat folder

HW due Thursday

Galileos and Einsteins- Tuesday night, Newtons Wednesday night:  Heat Homework in heat folder.

Heat HW Monday night

Heat Transfer Practice, in Heat folder.  Remember to put all work in your folder when done.

HW after Heat Day 1

Thursday Night for Galileos and Einsteins, Friday night for Newtons:

Read in The Physics Classroom, Tutorial, Thermal Physics, Lesson 1: Methods of Heat Transfer.

Remember that hot things have more KE than cool things, and that heat flows from hot things to cool things.  This lesson describes three ways in which the heat can be transferred.  For each method: conduction, convection and radiation, describe how the KE of the atoms in each substance is changed.

HW after Waves test

Final Unit coming up!

HW: Go to The Physics Classroom, Physics Tutorial, Thermal Physics. Read "Temperature and Thermometers," and "What is Heat?" up to 'The Zeroeth Law of Thermodynamics.'  Open a note in Notability and answer the following questions:

1.  How does The Physics Classroom define temperature?
2.  What happens to the volume of liquid in a thermometers when the temperature increases?
3.  How is a Celsius thermometer calibrated?
4.  Write out a table with the following temperatures in both F and C (you may have to look some up):
 a. temp at which water freezes/melts
 b. room temperature
 c. human body temperature
 d. temperature at which water boils/condenses

5. What is the Kelvin scale?  How large is a Kelvin degree compared to a Celsius degree?
6. What is absolute zero?  What happens at that temperature?
7. What term describes both how coffee cools down and soda (pop!?!?) warms up?
8.  What is thermal equilibrium?

Weekend HW: Wave review

Now posted in Waves folder.  Test Tuesday.  Extra help Tuesday morning X block for whoever wants it.

Wed/Thur night HW

Due Friday: Practice Test waves.  Reminder that there will be a real test first half of next week.

Tuesday night HW

All sections- do the "Electromagnetic Spectrum HW" sheet found in the Waves folder.

Test on Waves sometime early next week.

EM Spectrum

Due Tuesday all sections: EM Spectrum Research, in the Waves folder.  Nasa link here.

Tuesday/Wednesday night

Due Thursday for everyone:

Waves and Sound practice.

Reminder that we will be going outside on Thursday.  Dress accordingly.

Monday April 27

All sections-Finish up the Wave Properties Part 2 packet.

The Doppler Effect

Galileos and Einsteins, Thursday:

I am home with my son who is sick.  Please look in the Waves folder for lecture slides on The Doppler Effect, and fill in the notes on "Notes to go with Doppler Effect."  You should also review these images and animations below.

Imagine each of these dots is bobbing up and down on the surface of water, creating waves.

The dot on the left is does not move side to side as it bobs.  The dot on the right moves right.

Here's another view:

Now observe what happens to the frequency in front of the source vs. behind the source.

A similar effect can happen with sounds waves:

In the beginning the engine of the car is making sound, but the car is stationary.  Any observer would head the same pitch (frequency) sound.  Once the car starts moving to the left, the sounds waves to the left (in front of the car) are compressed, and the waves to the right (behind the car) are stretched.  How would an observer in front of the car hear the engine, compared to one behind the car?

Google a video of the Concorde producing a sonic boom.

No homework over vacation...have a nice break!

Same HW Wednesday night

If you didn't finish last night's HW, or if you did it and had questions, or if you did it and DIDN'T have questions but its a good idea to review...do Qs 1-8 on the wave calculation worksheet.

Pretend it's a test!  Show your work!  Include units!  Who knows, maybe there will be a quiz coming up!

Monday/Tuesday night

First night of Waves HW:

Use the "Slides on Waves and Vibrations Properties" document to complete question 9-17 on the "Waves Calculation Worksheet."  Then complete the second half of "Waves Calculation Worksheet," using the equations from the lecture slides.

Due Wednesday for everyone.

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.

Test Corrections and HW on Electrostatics

First- Energy Test corrections.

You may do test corrections up to a 37/52 if you earned less than 37/52.  To earn points back you must record your work on another piece of paper or on a Notability document.  Please turn the original test back as well.

For MC problems- indicated correct answer as well as an explanation OR calculation showing the correct answer.  MC problems that are not explained will not get credit.

Problem # 1( Roller Coaster):  Show all work.  You must set up the energy problem with a table, like you did in the Roller Coaster HW problem (go back in look in the Energy folder at that document, if necessary.)

Lab Practical:
Recall you had a cart going down a ramp.  You task is to find the velocity of the cart as it passes the blue tape marked on the ramp.

1.  Explain what three measurements you need to make.

2.  Set up a table as in the roller coaster problem.

3.  Either use the measurements you originally made, or make up some reasonable numbers to plug in.

4.  Show your work in the three energy calculations that are needed to solve this problem.

And now for the homework....


In complete sentences answer Qs 1-10 at the end of Ch 32 in the electrostatics reading.  Put this in your drive folder.  Galileos and Einsteins are doing this over the weekend; Newtons are doing this Monday night.

HW Thurs night Feb 26

Please go to the new Electrostatics folder, open Ch 32 and read pages 500-504 (sections 32.1-32.2).  Import this into Notability so you can highlight and take notes.

Things to focus on:

Three parts of the atom
Locations of these parts
The charges of these parts
How charges interact with other charges

Course selection, HW

Make sure you are logged in to Drive on your iPad.  Click here to indicate what science course you want to take next year (this is not the official sign-up- just a way for you to tell me what you would like for next year).

HW Tuesday night Galileos and Einsteins, Wed night Newtons: UG practice in the Energy folder.

HW Monday Feb 23rd

Read and answer the Sally Ride questions, both located in the Energy folder.  Remember that Drive is not super on-top of things, so search for the documents by name if they don't show up (Sally Ride article, Sally Ride questions).

Turn the questions in to your Drive folder when finished.

Energy Quiz Thursday/Friday

Like I said last week, we are still having the quiz on Energy at the end of this week.  There is no new material to learn this week, only review.

You should have finished up the stations lab if you had class today (Tuesday) or in class on Wednesday at the latest.

Check the answer key for the "More Conservation of Energy Problems."  Correct your work as needed (show all your work!!!) and turn in to the folder.  That will be graded.

Optional (but recommended) review guide is also in the folder.  I will post the answer key Wednesday after school.

Weekend HW

All sections- complete "More Conservation of Energy Practice."  Reminder that we will have a quiz on Work, Power and Energy on Thurs/Friday EVEN IF there is a snow day Monday. (Update: I'm revising my probability of snow day down to 50%.  They'll probably be able to clear the roads as it falls.  However, heaviest snow still forecasted for Monday.)

We will have one day to finish the stations activity next week.  Between the stations and the weekend HW, you will have plenty of practice for the quiz.

HW night of 2/4 and 2/5

Galileos and Einsteins- Wednesday night, complete the Rollercoaster and Pendulum problems.  The right-side up Pendulum problem is in the document called "Energy Pendulum Problem.pdf."


Newtons- this is your HW for Thursday night.

HW night of Feb 3

Newtons- please do the front page of "Understanding Energy" worksheet.  You will finish it the next night.

Weekend HW

Galileos and Einsteins, please do the "Understanding Energy" worksheet from the Energy folder over the weekend.  Remember to turn it into your Drive folder when you are done.

Rube Goldberg video

First Day of Quarter Three

Physics- all sections:   Please complete the calculations and questions for the Horsepower Lab.  All sections' data tables are posted in the Energy folder in the Shared Docs folder.

**If** school is canceled more than one day please finish the Work and Power practice (also in the Energy folder).


REMINDER that Drive isn't always finding all the documents that well- if you can't find the Energy folder or a document there try searching by name: HP lab Galileos/HP lab Newtons/HP lab Einsteins.

Momentum Study Guide Info

To qualify for momentum test corrections, your completed study guide MUST be turned into your Drive folder by 2:30 today (Thursday afternoon).  I will be putting the answer key in the shared folder at 2:30.

Momentum- quiz update

HW due Thursday is practice, "Cons mom probs" (conservation of momentum problems).  I also recommend starting the Momentum Study Guide.

UPDATE: The momentum quiz is going to be moved up a day so we can have two days of exam review.  Galileos and Einsteins will take the quiz Friday; Newtons will take it Monday.

First Day Back

Welcome back, everyone!  I hope you all had a restful break.

I did a lot of grading over break.  All assignments through December are in Aspen.  If you have NTI (not turned in) for an assignment, check the following:

• Did you do it in Notability, but forget to turn it in to Drive?
• Did you turn in as a PDF?  I can't open other formats.  Go back to Notability, choose PDF when you send it to Drive.
• Did you not do it....?  Find the assignment in Drive, complete and turn in ASAP.

Homework tonight: MCAS momentum problem, found in the Momentum folder.  Complete and turn in to Drive.  Make sure today's Conservation of Momentum Activity is turned in as well (the in-class assignment).

ALMOST FORGOT: Test corrections are due as well.  If you got below 51/68 AND you completed your study guide before the test you can do corrections (you will have a green R on your test). Correct MC questions and write one sentence explaining the correct answer.  Redo any open response  that were incorrect.  Turn in before the end of the quarter (next Thursday).

Reminder that there will be a quiz on Momentum on Tuesday January 14th.  This will cover momentum and impulse (from before break) and conservation of momentum.
