Eisco Garage Physics Catapult - Build Yourself - Premium 3/4" Pine

<b>The Eisco Garage Physics line is aimed at students interested in STEM concepts included physics and engineering. Each kit engages learners to discover new ideas about the physical world through assembly and play.</b><br>Catapults were one of the most influential elements of siege warfare over the last 2500 years. This model is closest in design to the Onsager catapult which was used by Romans to launch combustible projectiles at their targets. This kit is designed to be easy to build and fun to use, allowing students to literally play with the physics of catapults! Shoot ping pong balls over 20 feet and explore 12 different catapult geometries. Students can experiment with different arrangements until they find the optimal configuration! Educational topics covered in the kit include force, acceleration, center-of-mass, vector components, Hooke’s law, parabolic trajectories, and class 2 levers. Kit designed for exploration under the supervision and guidance of a scientifically-minded adult.<br><br>Kit includes catapult base, catapult left and right sides (symmetric except for counter-sinks), catapult lever arm, 8 rubber bands, 4 wood screws, 3 dowels, 1 c-shaped screw hook, 1 ping pong ball, cardboard storage box and instructions for assembly and experimental activities.
