Gear Ratio Instructors Sheet

 

Preparing:

 

        · Gather all materials needed for each set.  Each set should include a pegboard, 4 different sized gears, 4 shafts coupled with pins attached to twisty ties, 4 washers, 3 paper plates, paint, and finally the activity sheet. 

 

 

Set-up at classroom:

 

        · When you arrive at the classroom split the children into groups of two or three (use your discretion) and give each group a packet. 

       

        · Give an introduction on gears and the use of gears in everyday life.  (Please refer to the yellow handout on this introductory information.)

 

        · Show the children how to attach the gears on the pegboard.  This is done by putting the shaft through the gear, placing the washer underneath the shaft, and finally positioning the shaft through the pegboard and clipping it with the pin. 

 

        · Finally explain the object of the exercise and go through the activity sheet with them and explain any questions that they have with the exercise.
