Design & Engineering ChallengeFollow each step in the design & engineering process to develop a solution to the challenge.Place a check in each box as each step is completed. Fill in the blanks when necessary.

1. Identify The Challenge

Challenge: __________________________________________________________________________

2. Brainstorm Ideas & Solutions

Discuss design ideas.

Consider building components.

Sketch out design ideas on paper.

Choose the best design.

3. Build A Prototype

Use Kid Spark engineering materials to build a prototype.

4. Test & Improve The Design

Look for opportunities to improve the design. (Is it practical, proportional, etc..)
