Levers and Pulleys Simple Machines Lesson

A door is a type of lever. Depending on where you push on it, it takes more or less force (effort) to move it.  Some examples of a lever include the back side of a hammer, catapult, shovel

 

Lever Experiment for Kids

simple lever experiments for kids

We tried an experiment to show how levers work. We used a ruler, Lego Duplo as our fulcrum, and a book. Then the kids pushed down on the opposite end.

We experimented how moving the fulcrum (the tension point in the middle of the ruler) made lifting the book either harder or easier depending on which way you moved it. Having the fulcrum closest to the object we were lifting made it easiest .

This video does a great job of explaining how a lever words and comparing it to another simple machine.

Ever since our Medieval Ages history unit my kids are even more into castles. So we just had to make the common middle ages lever – a catapult.

 

Pulleys for Kids

A pulley is a simple machine with one or more grooved wheels connected by a rope. It is used for lifting, lowering, or moving objects. Some examples of pulleys include cable cars, ski lifts, playground zipline, and more.

   

Pulley Experiments for Kids

single pulley hands on experiment for kids

We made a simple pulley to send messages back and forth across the room. This kids thought it was hilarious!

Multiple pulleys make jobs easier

Then we tried an experiment using several pulleys. By having more than one pulley it made the job easier.

This experiment allowed our 4 year old preschooler to pull the rope at the end so that despite mommy and daddy pulling the sticks apart, they went together easily with just her little bit of effort.
