Students will create and design their personal keychains. Students will learn about 3D modeling using TinkerCAD and printing technology using 3D printers. The goal is to learn how to design a 3D model, apply concepts such as additive and subtractive design, and print using our 3D printers. In addition, students will gain 21st-century skills including creativity, critical thinking, collaboration, and communication. Every student will storyboard and present at the end of the session. The classes will educate kids about 3D printing and computer science. Students do not need to have 3D experience.
