Levers: A Mechanical Science Kit
The power of the lever is basic to mechanical engineering. Kids can learn how levers are used to increase force and lift heavy objects when they play with Engino's Levers: A Mechanical Science Kit. With a 36-page activity book and six or more working model projects, hands-on learning helps to cement an understanding of the technological principles of energy transfer and how the use of levers can change the direction of motion. Build a seesaw, a lever crane, a wheelbarrow, and more.
