Mobile catapult

The "Mobile Catapult" STEM kit offers an engaging blend of mechanical engineering and physics through the construction of a rolling catapult system powered by elastic energy. As children assemble this dynamic device, they will delve into the principles of energy conversion, learning how potential energy stored in stretched rubber bands can be transformed into kinetic energy to launch projectiles. This hands-on experience not only demonstrates the basic physics of energy storage and release but also introduces concepts such as tension, elasticity, and force. By adjusting the tension in the rubber bands and experimenting with different launch angles, students will gain insights into how these variables affect the range and trajectory of the projectiles, providing a practical understanding of projectile motion and the factors that influence it.

Additionally, the mobility of the catapult adds an extra layer of educational value, as learners explore the mechanics of wheels and axles. They will understand how these simple machines facilitate movement and reduce friction, enabling the catapult to be easily positioned and aimed. This aspect of the kit encourages young engineers to think about the interplay between static and dynamic physics principles, as they balance the stability needed for accurate launches with the ease of movement provided by the wheels. The "Mobile Catapult" STEM kit not only stimulates curiosity about medieval siege technology and modern engineering but also fosters problem-solving skills, creativity, and a deeper appreciation for the practical applications of physics in designing effective machines.
