Modeling Projectile Motion with Quadratics

The video tutorial covers the study of quadratic functions by 9th and 10th graders, focusing on real-life applications. Students build catapults to launch M&Ms, modeling the parabolic paths using quadratic functions. They are tasked with designing and constructing their catapults, measuring data, and refining their models. A competition is held where students use their models to hit a target. The project not only teaches quadratic functions but also incorporates elements of engineering and problem-solving, making learning engaging and practical.
