Since most students are working remotely, there a few ways to overcome the challenges of not being able to physically work together in their teams. In the event your students have trouble building a physical prototype, you can consider creating a digital prototype, which can serve as their final one for their Pitch. For 3D prototype models, we recommend Tinkercad, which runs in a web browser or an app. It is known for its simplicity and ease of use. Other digital solutions may include: a curriculum, website, and video games to name a few.
