Lesson 7PulleysLesson SummaryThis is a two day lesson to introduce and explore pulleys.Day 1: Building PulleysDay 2: Language Connection: retelling the story of The Frogs in the WellIllinois Goals and StandardsSCieNCe:12.D Know and apply the concepts that describe force and motion and the principles thatexplain them11.B.1a Given a simple design problem, formulate possible solutionsLanGUaGE aRts:1.B.1a establish purposes for reading, make predictions, connect important ideas, and link textwith previous experiences and knowledge4.B.1a Present brief oral reports, using language and vocabulary appropriate to the messageand audienceLesson Objectives• identify examples of pulleys• identify situations where pulleys make work easier• Explain how a pulley makes work easier• identify force being applied to a pulley to cause motion50 • Lesson 7: Pulleys
Day One● Time Allotment50 minutes● MaterialsTwo cans of paintRopeHook or rodPull, Lift, Lower by Michael DahlPer Pair of StudentsRulerScissorsPulley and cordEraser or other small item● Advance PreparationBorrow two cans of paint from the school engineerSet up a pulling station by tying rope to the handle of a paint can and looping the rope over apulley hung from a hook or rod. The book, How Do You Lift a Lion, has a helpful diagram ofa simple pulley set up.● VocabularyPulleyGrooveWheel● Background InformationA pulley is a simple machine that has a grooved wheel on which a rope can move. Pulleys makelifting objects easier.When you need to move a heavy weight, it is naturally easier to pull down than to pick up. Pullingdown uses your body weight and so requires less physical force. A pulley allows a load to moveupwards even though the force is downwards.The groove on the wheel reduces the amount of friction a rope encounters. A rope run through apulley will be moved more easily and last longer than a rope slung over a tree branch or a door.Pulleys help people move objects to high places while they stay standing on the ground. A flagpole is an example of this. With a pulley attached to the top of the flagpole, the flag can be raised tothe top by someone standing at the base.Sometimes people don’t do the pulling. Machines, like cranes, use mechanical force to pull but stillrely on pulleys to make work easier.Chicago Children’s Museum • 51
