By the end of this course your child will be able to identify all three classes of levers and different types of pulley systems and test them to determine how they operate. By comparing and contrasting how different levers and pulley systems function your children will more easily identify appropriate places where levers and pulley systems should be used. Real-life photos and key facts enhance the building instructions for the eight different real-world models. Models include: scissors, wheelbarrow, sailboat, block & tackle and more. 161 pieces for grades 3 - 5.

    Wonderful find. Highly recommended. August 23, 2010
    Reviewer: Rebecca from Cumberland, MD  
    I have two 'hands on' boys who love to build. When I wanted to teach them about simple machines I knew that building the machines would be an ideal way to make the concepts stick. Knex building sets make this easy to do. The set comes with all the necessary pieces, instructions and lesson plans. The pieces are durable and color coded so assembly is easy. The sets are ideal for families teaching multiple ages. My boys are six and nine. They easily built the models by themselves and then performed the simple experiments with my instruction. I plan to use these sets again when they are older because the lesson plans also include formulas for figuring out basic physic problems. Wonderful find. Highly recommended.
