Unique Construction, Cool Collectible

K'NEX Education Intro to Simple Machines: Wheels and Axles and Inclined Planes is designed to introduce students to the scientific concepts associated with two types of Simple Machines: wheels and axles and inclined planes.

This Equal Mass Density Set is for specific gravity and density determinations.

Take your study of pulleys and engineering to the next level!

Vividly demonstrate centripetal forces with this exciting apparatus.

This model shows the internal structure and operating principles of an air cooled two-stroke engine.

This model shows the internal structure and operating principles of an air cooled two-stroke engine. All parts are aluminum and plastic. Ignition is shown via a small bulb. Carburetor and fuel supply are also sectioned. Hand crank is provided for manual operation. Mounted on a base.

Great for studying the simple harmonic motion of a torsional pendulum.

Demonstrate the extension of a spring in relation to the force applied to it.

The mechanics kit for whiteboard demonstrations includes more than 25 large, colored, and easily distinguished components stored in a case with foam inlay. More than 30 experiments can be set up in rapid time. Large components ensure that experiments can be viewed from a distance. Secure attachment is guaranteed by high-grade AlNiCo magnets, allowing quick and easy configuration of experiments. Measuring units, vector diagrams, and explanations can be provided right next to the experimental configuration on the blackboard.

Consists of two interconnected cylinders of different diameters based upon two graduated glass syringes of 10mL and 50mL, with cross-sectional area of 3 to 1.

Studying dynamic tension has never been easier with this simple form truss kit. The kit includes a half-meter truss with hooks on both sides, V-shaped clamp.Recommended stand and rod, item 470137-892 Required but not included are masses and spring scale.

This pulley is ideal for use with photogates sensors. Pulley is mounted on free-running ball bearings with minimum friction. Mounted on a removeable rod of 150 x 10 mm diameter.
Diameter 65 mm with spokes
Ideal for use with Photogates

Show the difference between three pendulums with different lengths.

Sturdy box for investigating frictional forces.

Intro to Engineering welcomes young children to the field of engineering with 25 experiments and building projects in five sections.
