5.0 (1 rating)

The "Catapult Engineers" project is a hands-on, project-based learning experience for 5th-grade students to explore the scientific principles of angles, forces, and projectile motion by designing and building catapults. Through activities such as historical reenactments, constructing basic models, conducting experiments, and refining their designs, students investigate the impact of variables like angle and force on projectile distances. The project emphasizes applying the scientific method and engineering design process, encouraging students to hypothesize, test, analyze data, and communicate their findings effectively while meeting standards like TEKS 5.6.D and 5.7.B.
