Timberdoodle Co is thrilled to announce a brand new series by Engino Education called Mechanical Science. The series currently covers eight core subjects of mechanics: Levers, Linkages, Gears, Wheels & Axles, Inclined Planes, Pulleys, Cams & Cranks, and Screws. What sets Engino's Mechanical Science apart is not only the sophisticated, multifaceted Engino parts, but each set also includes both a superb building instruction manual and a forty-page activity book (with innovative experiments and detailed explanation of the different technological principles applied). With hands-on activities, interesting facts about a variety of subjects, and exercises and quizzes at the end of each experiment, these are the engineering sets homeschoolers have waited years for.
