Monster Truck Lab (Orange: 11/29)

We recorded position-time data for a toy monster truck as it ran along a meter stick.  We graphed the data and found the slope of the line represents both the speed and direction of travel.  In physics, these two pieces of information are called velocity.  We also found the y-intercept represents the starting position of the truck.

HW:  WS 1 i

Unit 3 Exam (Orange: 11/22 Black: 11/23)

I collected the Unit 3 Homework Packet and gave the Unit 3 test.

Monster Truck Lab (Black: 11/19)

Today we started the next unit for periods 2,4, and 6.  We recorded position-time data for a toy monster truck as it ran along a meter stick.  We graphed the data and found the slope of the line represents both the speed and direction of travel.  In physics, these two pieces of information are called velocity.

HW:  WS 1 is due AFTER the Thanksgiving break.  Study for Unit 3 test on 11/22.

Exploratorium Field Trip (Orange: 11/18)

Today was our field trip to the Exploratorium in San Francisco.  The alternate assignment is as follows:

Visit the Exploratorium Website.  Select 4 online exhibits that are of interest to you.  Write a one paragraph summary of each exhibit.  What is it about?  What did you learn?  Why did you choose it?  Bring me your summaries next week (November 22 or 23).

HW: Study for your test!!  Do the practice test and get a blank copy of the review sheet here.

Unit 3 Homework Packet

The following items should be in your homework packet.

Unit 3 Worksheet 1a (blue)
Unit 3 Worksheet 2 (tan)
Unit 3 Worksheet 3 (purple)
Trigonometry Review (green- periods 2,4,6 have a stamp)
Unit 3 Worksheet 4 (salmon)
Unit 3 Worksheet 5/Review Sheet (grey)
Notes: Newton's First Law Paul Hewitt Lecture or Alternate Assignment
Practice Quiz (corrected in red = 100 pts, not corrected = 50 pts)

Stamped items = 100 pts; unstamped but corrected = 50 points

Review Day (Orange: November 16 Black: November 17)

I stamped the Review Sheet and gave time to go over it in class.  You can check the answers here).  You can also download a blank review sheet if you would like to practice the problems additional times.  I also gave the practice quiz, since I did not have time to give a real quiz.  Please correct your practice quiz the same way you would a real quiz in class.  If your practice quiz is not corrected, you will only get half credit for it in your homework packet.

The test will be Monday, November 22 for period 5 and Tuesday, November 23 for periods 2,4,6.

You can download a practice test here.  Answers to the practice test will be available at tutorial only starting on Friday, November 19.

HW:  Study for the test (Review Sheet, Practice Test); assemble HW packet

More Trig and Solving for Forces at Angles (Black: 11/15)

I checked the homework (Trig Review Worksheet) and gave class time for WS 4.

HW:  Review Sheet

Mrs. Peters out- Review Day (Orange: 11/12)

Mr. Rann covered for me.  He checked WS 4 and gave time to work on the Review Sheet.

HW:  Finish Review Sheet

Looking at Forces from a New Angle (Orange: 11/9 Black: 11/10)

I checked and went over the homework.  There will be a quiz on WS 3 during the next block, so be sure to check your answers here.  I also gave the quiz on WS 2.

Many forces that we encounter on a daily basis act on the object at an angle.  For example, pushing a broom or pulling a wagon.  Therefore, we need to understand basic trigonometry functions and how to resolve forces into their components.  We discussed this in class and did a few practice problems.

HW:  WS 4, quiz on WS 3

We are about to accelerate (Orange:11/5 Black: 11/8)

I checked and we whiteboarded Worksheet 2.  I also gave a quiz on the Force-Mass lab.  Most of the period was spent working on problems where an object is accelerating and the sum of the forces is no longer zero.

Here are the answers to WS 2, sorry for the poor quality...My scanner isn't working.

HW:  WS 3; Quiz on WS 2

Force Diagrams with Numbers (Orange: 11/3 Black: 11/4)

We debriefed and turned in the Force-Mass lab.  We also reviewed extensively for the quiz by going over WS1a, then took the quiz on drawing force diagrams.  The remaining half of the period was spent learning how to solve force diagram problems when given numerical values.

HW:  WS 2

Force-Mass Lab (Orange:11/1 Black:11/2)

Today I checked and went over selected problems on WS1a.  You have two options to correct the answers for WS1a.  You can click here for a simple pdf document with the answers, or you can download the PowerPoint that shows you step by step how to solve each problem.  There will be a quiz on Wednesday (period 5) and Thursday (periods 2,4,6) on drawing force diagrams.

Most of the period was spent collecting data for the Force-Mass lab and learning how to make a mathematical model from two variables.

HW is to complete WS2 #1a,2a and #4a.
