Pinball Machine Design
	Poor (N/A)	Fair (N/A)	Good (N/A)	Very Good (N/A)
Engineering design	Poor Design does not allow for play.	Fair Design attempts to allow for play but needs outside manipulation to work.	Good Design allows for play but still has problems.	Very Good Design allows for play and functions very well.
Reasoning Materials and design explained (notebook)	Poor Reasoning present but shows a lack of effort and insight into the design. Necessary components are absent. Obvious flaws to design.	Fair Reasoning present but does not reflect the design or is very disconnected. Missing key explanations of design or materials chosen.	Good Reasoning present but needs more details.	Very Good Well described reasoning behind design and material selection. Shows well thought out with attempts made to better the product after initial testing and design.
Engineering process Followed process of design, build, test, refine to problem solve	Poor Failed to follow the basics of the design process.	Fair Followed design process but didn't want to make necessary improvements or adjustments in design or materials.	Good Followed design process made some improvements but gave up before machine worked well.	Very Good Followed design process continued to make improvements seeking to make machine work very well- not just good enough.
