Teach students about pulleys and gears with a variety of physics equipment. Experiment with simple machines and fundamental forces and discover the mechanical advantage of pulley systems.
These pulleys and gears are to illustrate mechanical advantage. They are light duty, but work perfectly for STEM projects and science studies. You can also choose complete experiment kits from Engino that are built around pulleys for kids.
For a less expensive choice, kids can build their own simple pulley system with only a few science tools (rope, pulleys, gears). And you can find them all here! Plus, you get discount pricing on bulk quantities of 10 or more.
Start with an introductory lesson and some hands-on activities with pulleys for kids setting up a block and tackle. Then move into more advanced pulleys and gears. Find single pulleys, double parallel and double tandem, and even triple parallel and triple tandem pulleys.
Note: We've found that the single pulleys work best when the string is weighted. Without weight, you may encounter string slippage. But attaching a 50-gram weight to the string allows proper function.
We get it. Science can be messy. But Home Science Tools' products and service can handle it.
Our products are durable, reliable, and affordable to take you from the field to the lab to the kitchen. They won't let you down, no matter what they're up against. Whether it's (over)eager young scientists year after year, or rigorous requirements that come once-in-a lifetime.
And if your science inquiry doesn't go as expected, you can expect our customer service team to help. Count on friendly voices at the other end of the phone and expert advice in your inbox. They're not happy until you are.
Bottom line? We guarantee our products and service won't mess up your science study—no matter how messy it gets.
