3.14Pulling Left,Moving Right
The horizontal pulley allows children to explore the possibilities
for reversal of direction when moving a load. Two pulleys are tied
to 6-inch hooks at each end of a pegboard divider or the back of a
shelf. Children discover that when they pull the rope in one direc-
tion, the load moves in the opposite direction.
This activity is appropriate for either
preschool or kindergarten children.
