Part of Lesson Plan: **5 Gases (updated) by Michael Fleming

Activity Overview / Details

Explain to the students that they will now go out in the shop and perform the same 5 gas analyzer procedures you demonstrated the previous day. They will work in teams and each student must be involved in testing the vehicle.  In other words, each student must handle and operate the analyzer. Remind them to calibrate the machine and to test the open air and gas tank filler neck. Explain to them that they may not disconnect sensors until they have completed the lab exercise and been stamped off.

Before the labsheet is passed out, go over safety. Have everyone place their safety glasses on their face. Talk about the dangers of carbon monoxide poisoning, in that all cars must be outside the shop. Also explain the wheels should be chucked, the parking brake applied and the car is placed in neutral or park.
