The Leonardo Da Vinci catapult model is scaled to size and fully functions to demonstrate the launching power of the catapult, a historical military device. The catapult flings soft clay balls (included) up to 15 feet to reproduce a realistic discharge, and is made of wood for durability. The model requires assembly. Mechanical models are typically built by hobbyists and model builders for personal use, or can be used as educational aids or projects in classroom settings. Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology. Whats in the Box?
