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  Either use the measurements you originally made, or make up some reasonable numbers to plug in.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