Look at a line of connected gears driving a conveyor belt to an oven. Examine the direction that each gear turns: clockwise or anti-clockwise. Look for patterns as more gears are added into the line. Turn a conveyor belt in a clockwise direction by choosing the direction of the first gear (driver). Record the direction that wheels rotate in cases where the total number of gears is odd or even. Identify the relationship between the direction of rotation of the first two gears and the total number of gears in the sequence. This learning object is the first in a series of six objects that progressively increase in difficulty.
Objective
1. Students distinguish between clockwise and anti-clockwise rotation.
2. Students identify a number pattern involving odd and even numbers.
