Prototyping
Teaching STEM
A prototype is a working model that is used to test a design solution and is typically what is built or created during a student “Design & Build” challenge.

Design Planning
Teaching STEM
A design plan lays out ways in which students will develop and test the agreed-upon solution to a Design & Build challenge.

Idea Generation
Teaching STEM
When searching for a solution to a design problem in the Design & Build process, many different ideas should be considered. Students may generate ideas to solve problems independently as well as in small and large groups.

Problem Identification
Teaching STEM
The first step in the Design & Build process is the identification of the key problem to be solved or need to be addressed.
