Week of 9-8

This week is all about motion - we finished notes on relative motion Monday (see older link) and worked some practice problems involving relating motion of two objects to one another.
Tuesday we did graph analysis and motion maps in our notes - copy from a peer if you missed it - they don't translate to the computer well.

Wednesday we are graphing the (fake) data from our motion maps yesterday - showing what acceleration looks like on both a position - time graph and a velocity - time graph, and showing how the slope and its units from each graph relate to what is happening to the object.

We also did a short activity with a wheel and axle, and described its motion with a graph sketch and a motion map, and reviewed the density topic.

Thursday we worked on this worksheet and watched a video clip on acceleration and what it means

Friday we will have a quiz over material from this unit; graphs, motion maps, and relationships involving position, speed, displacement, velocity, and acceleration.

Read p. 76-80, p.80#1-7  Due Thursday
Ranking Task W/S Page 1 AND Page 2 (handed out in class Wed) Due Friday - be sure to show some calculation or explanation!

Exam on Measurement, Density, and basic Motion will likely be next Wednesday

Thursday, 8-4

Today in class we will get to our motion notes (see previous post for a link) and work heavily with graphing the motion of different objects - it was supposed to be the focus of yesterday's "graphing motion" activity with the ping pong balls in the tubes, but I think many missed the point; I will be repeating today at the end of the slideshow to make sure we all understand the concept.

If we have time at the end of class we will discuss the answers you gave on the "growing and graphing" WS from Tuesday, and maybe the answers to today's homework that is turned in.

HMWK for Monday:
P. 879 #21-26
Show work with units!

Density Lab (optional online density lab as well)

Today we had our density lab; groups worked well to determine the density of 4+ unknown objects' densities, and checked answers somewhat by performing a "float" test.

Here's a copy of the lab handout in case you are one of the many who left yours in the classroom.
HMWK: Lab and Post-lab are due on Wednesday 

Optional Assignment (or think of it as a lab make-up for those absent or who had trouble with today's lab): Density Lab Simulation
Due no later than Monday, 9/8.  Print out your answers, or print out the sheet and answer it.  If you don't have a printer at home, see me in class and request a copy.

In class tomorrow we will discuss answers to the homework turned in on Friday, see what happens with your objects from the lab today and water/oil.  :)
We'll also take notes on graphing (and scientific method)

Next HMWK:  Due Thursday:
Read p. 22-26
p. 26#1,2b,5
p. 34#4,6,10

Measurement and Density

In class today (Tuesday) we finished up notes on measurement (see previous post for a link) and completed a measurement activity - the numbers on your worksheet need to be correct when you turn them in tomorrow.  One objective of this course is for you to be capable of using measurement tools properly to accurately represent a particular value; you will have some physical measurement question(s) on the end-of-unit exam.  (this skill will also be very useful in future labs/careers/life!!)
We also attempted another estimation; this time the length of the courtyard at school is the question.  Assuming no rain...  ? we will measure it tomorrow to see who's closest.
Wednesday in class:
Books will be passed out for those wanting regular texts.  Keep these at home!  

We will start notes on Density and have some fun activities and demonstrations mixed in as well Wed-Friday.

Homework:  will help give more background for density and wrap up some of the measurement topics we've reviewed so far:
Due on Friday: Read p. 14-21 in the text; work p. 21 #1,2,4,5    
Recommended extra problems:
P. 32 (chapter review) problems 2,4,9, 12-17 (except 15), 23,24, 27-29.
If you have any questions, you may come in and ask or see my teacher's edition to the textbook anytime!

On Friday in class we will go over answers to the homework, try some conversions between units, and see density demonstrations.  

August 28th (next Thursday in Science Club) we will try to measure a HUMAN's density!  Come and see, and bring extra clothes or a swimsuit!  :)
