What to Look For
Many children will pull the rope in the direction they want the
object to move and be surprised when it moves the opposite
Children will construct which way to pull the rope in order to
get the object to move in the direction they desire.
Two children may pull in opposite directions and have to
negotiate with one another in order to get the object to move.
Questions to Extend Thinking
How can you move the bucket?
What do I have to do to move the bucket over here?
Why did the bucket move this way when you pulled that way?
What happens if you pull the rope in this direction?
Add a second pulley to create a double pulley. This decreases the
amount of strength needed to move the objects.
Integrated Curriculum Activities
Incorporate a large horizontal pulley into a gross-motor area after
the children have had experience with the small pulley (see
Plan a math activity where one child decides how many objects
are to be transferred by the pulley and another child fills the
order. See More Than Counting, by Sally Moomaw and Brenda
Hieronymus, activity 7.13.
Add a small piece of colored tape to the rope to help children
visualize which direction the rope is moving.
