Mrs. GallPhysical Science Classes

FRIDAY, DECEMBER 11: DATA IS DUE TODAY! 200 POINTS

Friday December 11, 20091. Warmup: Is a light wave a compression

wave or a transverse (longitudinal) wave? 2. WORK WITH YOUR TEAM TO FINISH

YOUR CHOSEN LAB FROM WEDS. AND BEGIN CREATING A POSTER OR VISUAL AID TO SHARE IN CLASS ON MONDAY. (200 points) (Present today if prepared, 10 e.c.)

3. ALL SCIENCE FAIR DATA IS DUE TODAY.(200 points)

WAVES: TRANSVERSE, LONGITUDINAL, COMPRESSION You will not need any materials or preparation for this demonstration, except

that you will need some room. Have most of the students stand in a row at one side of the classroom, facing

out into the classroom. Let some of the students stand across the room from the line so that they can see the "waves".

Starting at one end of the line, have the students do a traditional stadium "wave". If they don't know how, have them all start slightly bent forward with hands on knees. Explain that the student on the end will lift both arms all the way over their heads and then put both down again. Each student should do the same motion as soon as (but not before) they feel the student beside them do it.

If they do it well, the students watching should see a definite transverse wave travelling down the line of students.

Starting with the same end student, next have the line make a longitudinal wave. Have the students start with their arms out straight in front of them. As the wave goes by, each student will swing both arms first toward, and then away, from the next student in line.

Let the students take turns being the first in line, being in line, and watching the line from the other side of the room. Let them experiment with different motions: hopping in place, swaying to the left and right, taking a little step down the line and back, doing a kneebend, etc. Which kind of wave does each motion create?

PHYSICS: Lab Presentation due Monday December 14: 200 points choose lab from list below. (or create your own

Friday December 11, 20091. Warmup: What is an ion? An atom, radical,

or molecule that has gained or lost one or more electrons and is charged

2. Oxidation: Magnesium burning3. Thirty element names and symbols quiz

Monday 12/144. Homework due Mon. P.165 #1-135. Memorize p.171 table 1 for quiz on Weds.6. Science Fair Data is due today: 200 points

12/2 Science Fair Notes page 14 Your DATA must be collected by December 11. The DATA TABLE that you use to turn in your data

will be a very organized, well – labeled list of all information gathered.

Observations and Measurements will be organized into a data table.

Additional Notes taken during the experiment should also be saved and turned in on December 11.

Full credit will be 200 points for your complete data table and notes turned in on December 11.

If you have not yet collected data… Turn in a labeled data table with no

observations or measurements filled in. At the bottom add comments:

When will you collect data? Any other information that will convince me that

you know exactly what to do, how to do it, and you have a plan.
