About STEM Challenges: Click here to learn more about the 3 Stages of STEM. STEM challenges are an engaging way to incorporate the engineering design process into your classroom or after school program! These hands-on activities allow students to work in teams, apply the engineering design process, and connect science topics to real-world applications. The teacher will provide the structure to the project, but students will take an active role in designing and building their own device.

Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
