Tuesday - Thursday, 9/30

Thursday/Friday Homework!! speed, acceleration, velocity. (get it here) due Monday.

Also, we had an experiment in class; the effect of (Your chosen IV) on (some measurement of speed). Students were to select their own IV and DV, create a hypothesis and procedure, and then measure in class today. Labs will be set up as follows;

Left page: Instructions:

How ____ affects / relates to ______

Hypothesis

Procedure

Data

Graph

Analysis/Conclusion

How to improve future tests (criticisms of your procedure or results that you could improve on with more time/resources)



Finish your lab by next week.

Friday: Matching graphs to descriptions (speeding up, constant velocity, etc. to Position - Time and Velocity - Time graphs)



Yesterday (wednesday) we worked practice problems in class, went over homework, and practiced using acceleration due to Earth's gravity to solve motion problems.





Tuesday we practiced problem solving and had homework (get it here) due Wednesday.

Monday, September 27, 2010

Friday and Monday, 9-27

Friday: We worked practice problems and did whiteboarding with ranking tasks, as well as going over the homework from Thursday.

Monday: Wheel and Axle lab (in class) and whiteboarding - Acceleration concepts!

Tuesday we will have homework in the form of a worksheet; it will be posted here later.

Physics: Graph racing and Hang time lab today. Finish as homework. Labs collected tomorrow.

Thursday, September 23, 2010

Thursday, 9/23

Today in class:
Practice converting units,
How to find slope of a graph (for yesterday's lab)
Notes: Changing Velocity
Homework: Read p. 76-80, p.80#1-7

Wednesday, September 22, 2010

Wednesday, 9/22

Answers to last night's practice w/s:
1. 130 km/h
2. 2 m/s
3. 24,000,000km or 24 million km 2.4x10^7 km, or 24 Gm
4. 0.085s
5. 18.5m
6. 34,545s (9.6h)


Announcement - Time Vault from 1998 to be opened tomorrow in room 314 at 7:10am. Read the (uncensored and previously unread) comments from 1998 teens after school in Science & Discovery Club. 2:30-3:30


Lab today: BB in a glass tube - analyzing its motion and how slope affects it.
Finish graphing on your own; we will discuss the post-lab analysis portion tomorrow in class and I will work a couple of examples.
Get a copy of the lab instruction sheet here.
Were you absent? Here's the makeup version of the lab.

Physics students: Labs will be collected tomorrow. You should have five; BB, calculating g, wheel and axle, human R/T, and the lab practical from today: finding time that a falling object interrupts a sensor beam.

Monday and Tuesday, 9-20/21

Monday: Discuss Friday's Exam (re-trying concepts from unit 1) and do test corrections to study in notebook.
Homework was p.93#23,25-27. #26 is referring to problem #25, not 13. You may correct it in your text. #25 is bonus; it's a tough problem.

Tuesday: Warm up problem: if A = 5 m/s and B = 10s, what is C if C = A/B ?

(0.5 is easy... the unit is the trick. Key here is to make the unit in the denominator (s) into a fraction (s/1) and multiply the numerator by its reciprocal. We'll see this new unit more in class soon.)

Discuss answers to homework

Class meeting - suggestions to improve class
Common suggestions from all classes:
Slow down / explain better (you have to tell me when...and I'm happy to!)
Fridays: Avoid homework, emphasize labs
No tests on Mondays
Use "whiteboard" activities more
Topic lists (in lieu of study guides) several days prior to exams
Extra credit - this won't completely happen, but I do have some upcoming optional assignments

Some classes had some extras; I'll try to make as many ideas as possible work.


Homework (optional) work practice problems on worksheet (here). Answers will be given out tomorrow.

Tuesday, 9-14

Freshmen: We will work on ranking tasks in class tomorrow and hopefully do a couple more practice density or conversion problems. Remember you can still come by to study or see your first exam after school.
Seniors: Nice job on the exam today. Tomorrow we will meet in the A+ computer lab for some graph matching fun.

Monday, September 13, 2010

Monday, 9-13

Physics: Exam tomorrow. Rank the ball diagram on your worksheet by velocity in preparation for the exam. We will be meeting in the computer lab again on Wednesday to do some graph matching (fun) after the exam.

Freshmen: Tonight's homework is to read p. 76-77 and work problems 21-26 on p.879.
PLEASE come in after school to look over your exam from last week; you can copy down questions and correct answers and get help if you don't know how to get a particular answer.

Weekend Homework

Freshmen: Remember you will have a second exam on Sci method, Density, Measurement, Conversions, and SI this Thursday - so study! You may come by before or after school any day to look at the last exam - the one Thursday will be similar but different.
Seniors - Exam 1 Tuesday, Weekend problems:
p.69#1-3,5,11,17,20,23,35,43,53. Make sure you give each one a solid try before Monday.
