Unit EQ: What skills are basic necessities for understanding technology?
LEQ: How do you choose the correct measuring tool?
Activating Strategies: Display all the different measuring tools and have a student choose one of them based on the teachers scenario of a problem. Example " Your family just bought a new entertainment center. Which room can we put it in? Which measuring tool would be the best to use?
Acceleration/Previewing/Vocabulary:
Volume, Distance, Pressure, Area, Volume, Electrical Properities, Speed.
Bench Rule, Sonic Tape, Tape Measure, Multimeter, Spark Plug Guage, Air Pressure Guage, In & Out Calipers, Torpedo Level
Teaching Strategies and Distributed Guided Practice/Summarizing Prompts:
Inform students they will be working in our lab. SAFETY is always the most important thing to remember when working in the lab.
There are 7 Stations that everyone should be completing. Teacher will review the proper use of each tool as it relates to the lab station. When we enter the lab:
Form a big circle, nobody's view should be obstructed.
Please follow along on the lab instruction sheet.
Please adjust your circle as teacher moves from station to station.
Review the workstations (in order from #1 - #7) explaining what the student is expected to do.
Point out common mistakes at each station.
Name of tool used and correct unit of measure must be included.
Only 1 item measured at each station except wire continuity (Station #5 - complete all 4)
Students may work collaboratively to measure all the products. *NOTE - all students need to operate/measure with all the tools for better understanding.
Assemble students back in classroom and check to see that each student has completed the lab including correct name of the tool used to measure and the units of measure for that tool
Pressure Guage - PSI (pounds per square inch)
Spark Plug Guage - metric mm or decimal inch
Calipers - inches/fractions
Mutilmeter - volts or ohms
Sonic Tape - Feet - ft. - ' and Inches - in. - "
Discuss with students the common problems that students experience with this lab
Pressure Guage - making a tight seal on the valve.
Spark Plug Guage - forcing the guage into the gap and stretching/spreading the actual gap of the spark plug
Multi meter - reversing polarity
Sonic tape - unreliable - measurements very inaccurate.
Summarizing Strategies:
Ask some simple recall questions from the measurement lab.
What unit of measure is used when testing a battery? (Volts)
Which is more accurate a sonic tape or a tape measure? (Tape Measure)
