Whiteboard WS 1

I checked the homework and we spent most of the period whiteboarding it.  You can double check your answers here.  I also collected the hovercraft lab.  We also did a practice quiz and corrected it.

HW: WS 2; Study for quiz on WS 1

Hovercraft Lab

I debriefed the Circular Motion station lab and collected it.  Most of the period was spent collecting data for and completing the Hovercraft Lab.  The last 20 minutes students were able to work on the homework.

HW: Unit V WS 1; finish lab if you didn't finish it in class

Circular Motion Stations Lab

We finished up our study of projectile motion with a quiz and watching the Mythbusters episode "Bullet Fired vs. Bullet Dropped".  We started our study of Circular Motion by investigating a number of activities set up at the lab stations.  If you were not at school, please

1.Download the lab by clicking here, and print out a copy.

2.  Copy the background information about the 3 main points of circular motion.
•An object in circular motion is always acted on by a force directed toward the center of the circle.
•If the force is removed, an object will travel in a straight line tangent to the circle due to inertia.
•Because there is a force acting toward the center of the circle, there is also an acceleration acting toward the center of the circle.


3.  Carefully read through the description of each activity and make a prediction about the results, or how you can most effectively get the experiment to work.

4.  Then watch each video posted at Mr. Hammack's site and describe the results of the experiment.  (For Experiment 8 you will need to use your own heavy textbook).

5. Using the background information at the beginning of the lab, see if you can explain your results.

The lab will be collected at the next class period.

HW: Finish lab if necessary

Bullseye Lab

I checked the homework and we read the article about the Mars orbiter that failed due to a metric mishap.  Most of the period was spent completing the Bullseye lab.

HW: Correct WS 1; Finish and Correct WS 2; Quiz on WS 1 and the first page of WS 2

Projectile Motion Simulations

We got new seats and I passed back papers.  I also checked the homework and we went over it.  We learned more about projectile motion by using an online simulation.  Click here for the link.

After that we took more notes on projectile motion and completed the Cancun Problem.

HW:  Finish WS 1

Acceleration Test

I gave a brief review and collected homework packets.  I gave 70 minutes to complete the test.

HW:  Projectile Motion Anticipation Guide (Part 1) and Snowboarder Problem on back side

Review for Acceleration Test

I checked the review sheet and worksheet 3.  We did the Reaction Time Lab and corrected quizzes 1 and 2.  I gave time for students to correct the review sheet and we went over worksheet 3.  We then took a practice quiz on instantaneous velocity then graded it right away.

HW: Correct Youtube Physics; assemble HW packet; study for test; complete practice test (due tomorrow at tutorial for ALL periods!)

Youtube Physics

We took the quiz on WS 2, then watched the Mythbusters Penny Drop episode.  The second half of the period we did the Youtube Physics activity.  You can watch the videos here:

HW: Finish Review Sheet (Due Tuesday for Orange Day Classes, Wednesday for Black Day Classes); Test on Thursday (Orange) and Friday (Black)

Free-Fall and Terminal Velocity

I checked Worksheet 2.  You need to correct it in preparation for the quiz next time.  We also corrected the Kinematics Curves Quiz and took the quiz on Worksheet 1.  The majority of the period we discussed the results of the pumpkin drop, and free-fall with and without air resistance.  The best example of free fall without air resistance is the experiment the astronauts did on the moon.

For periods 1 and 3 I also lectured on Average vs. Instantaneous Velocity.

Periods 1 & 3
