12/21

Objective:  SWBAT practice solving problems involving gas laws and thermal expansion.

Warm Up:  Pick up three pages and staple.  Answer question number 1.

12/20

Objective:  SWBAT calculate the thermal expansion of a solid

Warm Up:  Determine the energy given off when 5 kg of water is cooled from 80 oC to -15 oC.

12/19

Objective:  SWBAT understand heat transfer

Warm Up:  Pick up 6 (yes 6!) handouts.

Convert -  36 oC to oF
                 75 oF to oC
                 95 oC to oF and to K

12/15

Objective:  SWBAT review for tomorrow's midterm exam.

Warm Up:  Get out your review packet.
Draw a graph that depicts the potential energy of a pendulum vs. time.  Superimpose over that graph the kinetic energy of the pendulum over time.

12/14

Objective:  SWBAT review for Friday's midterm.

Warm Up:  get out your midterm packet (I gave them out last Friday).  Answer question 1.

12/13

Not much to post this week.
Yesterday we reviewed (while many of you were having group pictures taken).

Today is the Chapter 11 test on Fluids

Wed and Thursday we will review for the midterm.

Friday is the midterm.

Next week we will start Ch 12, so if you are going to be gone, please get the syllabus ahead of time so you can work on the homework assignment.

12/9

Objective:  SWBAT solve problems involving fluids.

Warm Up:  In a car lift, compresses air exerts a force on a piston with a radius of 13 sm.  This pressure is transmitted to a second piston with a diameter of 1.04 m.  What force must the compressed air exert to lift a 1.2 x 10^4 N car?

12/8

Students who were absent yesterday and want 15 more minutes to finish their FRQ's from Tuesday should come today during A lunch to finish them.

Objective:  SWBAT determine the bouyant force on an object experimentally.

Warm Up:  Pick up one lab packet and SILENTLY preread the procedure.

12/07

The day that will live in infamy....

Objective:  SWBAT calculate the volume of water needed to float a boat.

Warm Up:  Pick up your orange reference sheet and equation sheet.  You will have 10 minutes to finish your FRQs from yesterday.

12/5

Objective:  SWBAT prepare for tomorrow's test


Warm Up:  A 0.500kg object is attached to a spring of spring constant 30N/m and

released from rest at t=0 from a position 0.25m from equilibrium.

Find the equation that describes its x‐location as a function of time.

12/2

Objective:  SWBAT understand the factors that affect simple harmonic occillators.

Warm Up:  Turn in your Ch 10 HW.  What is the period of a 1 m long pendulum n the moon?  If I moved the pendulum to the earth, what would I need to do to it so that it would have the same period here on earth?

12/1

Yesterday Dr. Lewin entertained us by deriving the equations for the ocillation of a mass-spring system and for the period of a pendulum before becoming a human pendulum bob.  The links to MIT courseware are to the right in the blog and the video lectures (even though they contain a little calculus) are excellent ways to review before a test or for the AP exam!

Objective:  SWBAT develope and test a method for determining if a spring and a rubber band obeys Hooke's Law.

Warm Up:  Pick up a lab packet.  Do the prelab activity for Part 1.
