Timberdoodle's review Learn more
Does the wheel turn the axle, or the axle the wheel? How does the size of a wheel and axle affect the work performed? Why are inclined planes, wedges and screws categorized together and how do they make work easier? By building seven different real-world models, like a well, paddleboat and hand drill, your children will learn the answer to these and other pre-engineering questions. 194 pieces for grades 3 - 5.

    These are so great!!! October 19, 2010

    I am amazed at how these K'Nex unlocked understanding and creativity in my boys!  They can build with them for hours.  I love that they are able to follow the well-designed pictured instructions.  I feel that these K'Nex gave my boys something valuable in their construction abilities and understanding that I would not have been able to give them on my own.  They are fantastic!
