Subject: Planning Notes re: GYM, Vernier Logger Pro & Motion Detector

Tech Tips
---------

* File/Open.../ (navigate to folder)
* Click <Collect> button [student moves in order to match graph]
* Experiment/Clear Latest Run (or Edit/Undo Collect)
* File/Open.../ (new matching file; DO NOT save changes!)

Lesson Sequencing & Lab Procedure
---------------------------------

> Brief discussion re: how motion detector works (using ultrasound)
> RSLG - "Graphing Your Motion - Interpreting Distance-Time Graphs"
Logger Pro/File/Open... in the following order:
* 35a_Graphing-Your-Motion_modified.xmbl - Intro activity; open-ended 
experimentation in order for students to become familiar with set-up
* Distance-Match-A.xmbl thru Distance-Match-F.xmbl - Record B-F in RSLG
data table

[Note: Distance-Match-A_modified.xmbl is a two-page "how we did it" file
(virtually identical to Distance-Match-A.xmbl); see Data Table on Page 2.]

* Distance-Match-2_modified_ver2.xmbl - Match graph of mathematical 
equation: (0.02*Time^2)
... or expressed as a function:
derivative("Position", "Time")

[Note: Distance-Match-2_modified_ver2.xmbl was modified for a starting
position of 1 m, slightly farther than the closest effective range of the
Vernier motion detector. ("The Motion Detector does not properly detect
objects closer than 0.45 meters due to the time it takes to switch from
ultrasound emission to ultrasound detection mode. The maximum range is
about six meters...." Reference: Vernier FAQs.)]
