Category Description for Pathfinders Wooden Model Kits:

The main purpose of these all-natural, untreated wood kits is to demonstrate scientific principles in action. Heres how they work: each kit comes as a set of pre-cut wooden pieces, which are assembled according to illustrated black and white instructions. Once you finish putting everything together, the set becomes a fully-functional scientific or historical representation. The catapult, for example, stands at 8 tall, 5 wide, and can fling small objects over 15 feet. But its not just a glued-together wooden frame with a rubber band attached; these kits are put together almost precisely how the real thing was, using only authentic parts. Small wooden pegs (miniature versions of the huge pegs used in the real deal) connect crossbars, supports, and pieces of the frame just as nails would in modern-day building projects. A tiny rope strung through the middle and wound by torsion bars gives the catapult its power, allowing it to hurl miniature stand-ins such as fruit, marshmallows, or even tiny rocks in the exact same way several-hundred-pound projectiles were once thrown in medieval times.

The attention to detail and precise engineering of these kits is absolutely wonderful. While this level of complexity increases the time it takes to put together these kits (about 1 to 2 hours), it also drastically improves the functionality and realism. Kids can learn not only how modern and medieval inventions were put together, but they can also see the scientific principles in action that make them work. The creator of these kits even suggests combining the medieval siege weapons with math and physics lessons to learn about trajectories and graphing. The hydraulics-powered Robotic Arm is a great example of a scientific principle in action. Using three different syringes on a control panel of sorts, the arm can be used to move up and down, turn, and grab objects between two foam panels.

All kits are fully interactive. Catapults and trebuchets throw things, bridges can turn and lift using cranks and other wooden controls, and hydraulic machines can be controlled by liquid-filled syringes. These kits are also made to be supplemented with other toys; kids can use LEGO figures or other toys to man siege engines or operate bridge controls as a miniature train or other vehicle starts to cross. For more advanced builders and artists, all kits can be painted piece-by-piece to look even better.

For my son who loves bridges.

Student project in engineering class so students have a basic idea of how the design works. They will then model their own variation and operate it with hydraulics.
