Design and Modeling invites students to explore the design process as they take on real-world challenges in creative and hands-on ways. Right from the start, students are introduced to a central problem and continue making meaningful connections to it throughout the unit. Along the way, they learn how to communicate their ideas through sketches, 3D models, and simple mathematical representations. Students discover how these models can be used to simulate real situations and gather useful data. Working in teams, they research, identify needs, and collaborate with stakeholders to design and build a toy or game for a child with cerebral palsy. Through testing and iteration, they refine their creations—gaining valuable insight into how thoughtful design can make a real impact.
