Timberdoodle's review Learn more
Can your child identify different types of gear configurations and test them to determine how they operate; discuss what a gear ratio is and how it is calculated; compare and contrast how different gear configurations function; determine how different gear configurations change the amount of applied force, speed or direction of movement; and identify appropriate places where different types of gears are used? Can you? Well, you both will be able to after completing K'nex's Gears set. This set includes building instructions for six different real-world models, each model with relevant photo and key facts.

    a GREAT way for a child to learn physics February 10, 2011
    Reviewer: Rebecca from Federal Way, WA United States  
    As many books as we've read on the topic, nothing can do the job better than these kits! with detailed directions and a great case to keep them separate from all the other K'nex, this is definately a winner.

    Another winner from Timberdoodle! October 17, 2008
    Reviewer: Sandra from Boynton Beach, FL  
    I bought my 6.5 year old son this K'Nex set because I wanted a specific way to challenge him in new engineering and building methods.  He spends many hours with Legos during the day, but I would like his mind to be more well rounded.  This suited him perfectly.  I assigned one project at a time, and he was able to follow all the steps with minimal help from me.  He enjoyed doing it mostly on his own, but I enjoyed the opportunities to walk him through the challenge of thinking outside the box, and tackling a new sort of building toy.  They are also very well made, and next to impossible to break, with a sturdy reusable storage case.  Once again another winner from Timberdoodle.

    K'nex Simple Machines October 17, 2008
    Reviewer: susan mullens from bonaire, GA United States  
    I have four children ages 14, 12, 9, and 6.  You can't go wrong with K'nex simple machines.  The sheets show them what to do and they do it on their own.  My kids love to play with the gears and spin different, creative things of their own.
