5. Lab
A1 Uniform Motion
Discuss
lab background and design of air table and spark apparatus. Air table will
reduce (but not eliminate) friction. Focus on safety and breakage as well as
twisted tubes and operation of control pedal. Emphasis that
the air table is a precise instrument and not a ÒtoyÓ.
Focus
student attention on areas of lab report to complete. Evaluation will be
discussed later (as will the Lab Appendix B).
Do
Lab A1 in groups of 4.
Cycle
the students through the lab and monitor their use of equipment.
Approximately
8 – 10 minutes per group.
6.
Graphing
Process

handout outlining graphing process. Students are to read and note examples.
Do
Exercise A2 while waiting turn to do lab.
