My kids spent the whole afternoon building the lever models and testing how different fulcrum positions changed the effort needed. The pieces click together solidly enough that the finished constructions don't fall apart when they get excited. This is exactly the kind of hands-on investigation the d

This kit has held my third grader's attention for hours as she figures out how each lever and pulley actually moves real weight around. The included hands-on models make abstract concepts like mechanical advantage click into place without any screen involved.
