The purpose of this project is to immerse middle school students in the practical exploration of energy transformation through the construction and experimentation of popsicle stick catapults. By engaging collaboratively, students will strengthen their abilities in decision-making and leadership while gaining a historical and scientific perspective on mechanical design principles. This hands-on experience will bridge ancient technologies with contemporary engineering challenges, fostering critical thinking and innovation.
Learning goals
Students will develop a comprehensive understanding of energy transformation by constructing and experimenting with catapults, furthering their grasp of potential and kinetic energy principles. They will engage in collaborative design and decision-making processes, enhancing their problem-solving and teamwork abilities. Through historical exploration, students will link past engineering feats with current technological applications, deepening their appreciation for the evolution of physics and engineering in society. Additionally, students will practice critical feedback and reflection, improving their capacity to critically evaluate and refine their own work and that of others.
Competencies
Collaboration - Students co-design projects with peers, exercise shared-decision making, strengthen relational agency, resolve conflict, and assume leadership roles.
Products
Students will create functional popsicle stick catapults, demonstrating their understanding of energy transformation through meticulously altered designs for improved efficiency. Alongside the physical models, students will develop research-backed poster presentations detailing their design process and historical context associated with catapults. The timeline installation will feature replicas of historically significant catapults, paired with insights from students on how these innovations informed modern engineering. Additionally, each student will maintain a reflection journal documenting their learning journey, challenges faced, and the evolution of their understanding of potential and kinetic energy.
Launch
Begin the project with a dynamic 'Physics in Action' demonstration, where students observe first-hand transformations of energy through a series of interactive experiments showcasing potential and kinetic energy. This will lead into a 'Catapult Design Lab', fostering collaborative brainstorming, sketching designs, and testing prototype structures using diverse materials. With these activities, students will engage thoroughly as they draw initial connections between real-world physics concepts and the design and operation of catapults, setting an exciting foundation for their project.
Exhibition
Host a 'Catapult Carnival' where students showcase their catapults along with interactive stations demonstrating energy transformations. Each student will lead explanations and live demonstrations, engaging visitors in Q&A sessions to deepen understanding. Activities will also include a launching competition to highlight precision and modifications, fostering an immersive environment for students to articulate their learning journey and for the audience to appreciate the science behind catapults.
