  Nothing for now...

1.  We broke up into teams in the back of the room and went over the answer key to the worksheets that were assigned as homework

2.  Mr. Kleiner gave a short lecture to introduce a new formula Vavg = (Vf + Vi)/2

3.  We performed a lab to determine the value of the acceleration of gravity, also known as g.

homework: read sections 4.5 to 4.9 in the book.  There will be a reading quiz on tuesday.  You can use your notes, as always.

1.  We went over the answers to chapter 4 worksheet 1.  Those who did not want to participate in a discussion of the answers could work in the back on a challenging problem worksheet

2.  For the rest of class students worked on either the challenging worksheet or the regular worksheet.

homework: You can choose to do either of the two worksheets, but one of them is due tomorrow!

1.  We took a Reading Quiz #3 covering 4.1 to 4.4 in the book

2.  Mr. Kleiner gave a lecture covering the following: speed, velocity, acceleration, vectors, scalars, dimensional analysis, scientific notation on calculators.  We investigated m/s² which is a common unit for acceleration.  We wanted to know what the s² means mathematically and conceptually.  We also focused on understanding that velocity and acceleration are vectors.  Hence, a change in direction even at constant speed (such as a car going in a circle at 60mph) is still classified as acceleration.

Homework: Finish Chapter 4 worksheet 1.

1.  We went over the homework problems from chapter 3

2.  We spent 5 minutes silent time flipping through our books to get a feeling for what we will be covering this year in physics

3.  We read an article about the origin of the SI and MKS system.  How do we define a Kilogram?  What is a second?

4.  We spent the rest of class reading 4.1 to 4.4 in the book silently.

Homework: Prepare for reading quiz on 4.1 to 4.4 from the book.

1. We took the reading quiz covering pages 33-40 in the book

2.  Mr. Kleiner encouraged students to get started with physics on the right foot. If any student is worried about this class or having difficulty with the class then see Mr. Kleiner now…do not wait until it is too late to ask for help.

3. Mr. Kleiner gave a short lecture on volume, density, frame of reference

4. We watched the Eureka episode 2 video on Mass

5.  We learned how the inertia of a very massive object can be used to stabilize a skyscraper during an earthquake.  Check out the following link: http://blog.longnow.org/2008/06/25/728-ton-pendulum (period 1 missed this, so ask me to see this tomorrow in period 1)

6. For the rest of class students worked with partners to perform the homework problems

Homework: Problems 12,16,17,18,20,21,23-27,32,33,37,38,40 from chapter 3

1.  We turned in the mass vs weight lab

2.  We took a quiz on page 13,16,17,28-32 reading assignment

3.  We had a lecture on mechanical equilibrium, net force, inertia, and friction.  We read about Galileo from the book and discussed some of the interesting ideas from his story (persecution for ideas, longevity of aristotle’s ideas even though they were wrong, becoming blind during scientific research).

4.  We went into the hallway and examined newton’s first law by observing a book and a ball as they were at rest and and as they moved across the floor.

5.  We watched the eureka video on inertia.

Homework: Read pages 33-40 in the book.  Open note (not open book!) quiz on Monday.

1.  The homework assignment “what is the difference between mass and weight” was stamped by Mr. Kleiner, followed by a discussion (5 min)

2.  We reviewed what we learned from the falling objects mini lab from yesterday.  Most students did not know before this lab that mass has no impact on how fast an object will fall.  An elephant and a baseball will fall from the sky at the same rate.  The only thing that does impact how fast things fall is air resistance, which is related to the surface area of the object.

3.  Mr. Kleiner gave an explanation of a spring scale and a balance

4.  We performed the mass vs weight lab.

Homework: The mass vs weight lab is due tomorrow.  Also, read pages 13, 16, 17, 28-32 in the book.  There will be a quiz tomorrow to confirm that you read the book and understand what you read.  You may use any notes you took about the assigned reading during the quiz (this is to encourage you to take notes!)

1.  Reviewed answer key to warmup drills worksheet.

2.  Took a survey to see who has a computer connected to the internet at home

3.  Introduced the class to the trigonometry summary sheet.

4.  Expectations for class materials requirements were specified.

5.  Performed the falling objects mini lab.

Homework: What is the difference between mass and weight?  Bring in your answer hand written.  You can put your answer on the same sheet of paper you used for the hadron assignment.

1. Mr. Kleiner checked the hadron homework (5 min)

2. We discussed the hadron and the LHC. Most students still did not know what a hadron was even though it was assigned as last night’s homework. Students need to learn to understand what they read and write, instead of simply turning in a definition with words that they don’t comprehend (10 min)

3. Lecture on scientific notation, rearranging equations, plugging and chugging equations, and sin, cos, and tan. (25 min)

Homework: Complete the warmup drills worksheet handed out in class.

1. Introduction to the field of physics (10 min)

2. Discussed the syllabus and rules addendum (15 min)

3. A little about Mr. Kleiner (5 min)

4. Discussed the LHC and watched the following video (15 min):

Homework: Research the word hadron. Turn in a sheet of paper with a hand written explanation of a hadron that is thorough (more than one sentence!)
