Build a model or prototype of the proposed solution, as part of a team.

Building should include

• using detailed drawings (e.g., paper and pencil, computer-aided design)
• building a simple model
• assessing the model for possible problems
• producing your model or prototype
• testing the model or prototype

• physical testing
• experimenting
• evaluating how it meets criteria
• evaluating appropriateness of materials
• improving the design.

Process/Skill Questions:

• What are ways a group could split up responsibilities?
• Why is building a model/prototype important?
• What possible problems might the team encounter during a model/prototype build?
• What factors might influence design improvements?
• What tradeoffs were made in the design solution?
