Analyzing the data allows them to draw conclusions about how changes in the design or launch parameters affect performance. This process involves testing, data collection, and analysis to find the most effective design.Īfter launching the projectiles, kids can measure and record the launch distances at different angles or with different weights. Kids can experiment with different designs, sizes, and materials to optimize the catapult’s performance. They also explore geometric principles when determining the launch angle and trajectory of the projectile. Kids use mathematical concepts to measure and cut popsicle sticks accurately. Kids must consider factors like stability, tension in the rubber band, and the angle of launch to optimize the catapult’s performance. Kids explore the mechanical aspects of how levers work and how the components of the catapult interact to achieve a specific function.ĭesigning and building a functional catapult requires problem-solving skills which is the engineering component. Learn more about how a catapult works below.Ĭreating a popsicle stick catapult uses technology as it involves designing a simple machine. These Popsicle stick catapults make a great STEM activity! Building a catapult involves understanding basic science concepts such as force, motion, and energy transfer.
