STEM-ID Engineering Explorations introduces the Engineering Design Process. Below is a 2-3 week module that covers the concept of prototyping a product.   

Students work with a partner and each designs a desktop holder for their partner’s cell phone per their partner’s requirements. Students must document the problem and the requirements and design a solution that meets their partner’s approval. They render their design using 3-D modeling software and test the dimensions. Final solutions are 3D printed for additional testing and presentations.
