K'Nex - Intro To Simple Machines: Gears

Discover how six simple machines work as you construct a bicycle, egg-beater, crank fan, and more. Learn about three different types of gear configurations (spur, crown, and sprocket) and how they function, then use this knowledge to create your own machines!

This kit comes with 198 snap-together pieces and a project guide, all in a sturdy plastic storage case. Includes a CD containing the 39 page teachers' guide.

Key science concepts that can be taught and learned with this kit include:

• Identify 3 different types of gear configurations and test them to determine how they operate
• Discuss what gear ratio is and how it is calculated
• Compare and contrast how different gear configurations function
• Determine how different gear configurations change amount of applied force, speed or direction of movement
• Identify appropriate places where different types of gears are used

From the Manufacturer

Sprocket Gears! Spur Gears! Rack & Pinion! And More! The K'NEX Education Intro to Simple Machines: Gears set is designed to introduce students to the scientific concepts associated with gears. Students are provided with the opportunity to acquire skills using a hands-on, inquiry-based approach to information and concepts as they build, investigate, discuss, and evaluate scientific principles in action.

The Teacher's Guide provides the information and resources needed to build students' understanding of scientific concepts and channel their inquiries into active and meaningful learning experiences. Extension activities to explore the concepts more deeply are also included.
