2007年3月1日 · The K'NEX Education Intro to Simple Machines: Levers & Pulleys set is designed to introduce students to the scientific concepts associated with two types of Simple Machines – levers and pulleys. Students are provided with the opportunity to acquire skills using a hands-on, inquiry-based approach to information and concepts.

Two triple-pulley blocks make it easy to build machines with mechanical advantage up to 6:1. Build all three classes of levers with our pair of 20-cm levers, or combine gears, levers, and pulleys together to show how rotating machines work.

Discover how eight simple machines work as you construct a balance, wheelbarrow, scissors, a block and tackle, and more. You'll understand how all three classes of levers work and see …

Build 8 different replicas of real-world models, one at a time with K'NEX Levers and Pulleys. This elementary physical science kit includes building instructions with real-life photos and key facts for each model

2019年5月1日 · Through 26 model-building exercises, you'll investigate all six classic simple machines — wheels and axles, levers, pulleys, inclined planes, screws, and wedges — as well as gears. and then move onto larger, more complex models to push the machines harder and see how they can work together.

2013年10月1日 · This wooden machine has a sturdy wooden construction ideal for classroom use. This apparatus can model how the use of several pulleys increases one's mechanical advantage. Students can use this both qualitatively and quantitatively and its design lends itself easily to inquiry based activites.

Students will explore through hands-on investigation 1st, 2nd and 3rd Class levers along with fixed, movable and combination pulley systems. Includes building instructions for 8 different models with real-life photo and key facts.

TecQuipment's Simple Machines Kit Package (ESB3 - Package) contains one of the Pulley, Drive Systems, Gear Trains and Centrifugal Force Kits, plus four Work Panels (ES1). Demonstrates the mechanical advantage of different combinations of pulleys and a …

This economical version of our Forces & Simple Machines Kit, this set is ideal for introducing students to the concepts of changing force by levers and pulleys, and the notion of mechanical advantage. The manual describes experiments with the three types of levers, single and double pulley systems, and shows the characteristics of each machine.

Explore the mechanics of simple machines with this 5-in-1 kit from Learning Resources! Build a lever, pulley, inclined plane, wheel and axle, and wedge all at once. Perfect for hands-on STEM learning.
