Raft Blueprints	4		3	2		1
Blueprint - Details	All assigned details have been added. The details are clear and easy to identify. The blueprint looks like the model.		Almost all assigned details (at least 85%) have been added. The details are clear and easy to identify.	Almost all assigned details (at least 85%) have been added. A few details are difficult to identify.		Fewer than 85% of the assigned details are present OR most details are difficult to identify.
Blueprint - Accuracy	Structures are drawn accurately with precise measurements. All assigned structures are measured accurately.		Most of the assigned structures are drawn accurately and are measured. All assigned structures are measured accurately.	Few of the assigned structures are drawn accurately and are recognizable. Few of the assigned structures are measured accurately.		None of the assigned structures are drawn AND/OR measured accurately.
Blueprint - Labels	Every item that needs to be identified has the materials and the label. It is recognizable which label goes with which structure.		Almost all items that need to be identified have materials and labels. It is clear which label goes with which structure.	Most items that need to be identified have labels. It is clear which label goes with which structure.		Few of the items that need to be identified have labels OR it is not clear which label goes with which item.
Raft Construction and Success	4	3			2	1
Testing - prototypes	Clear evidence of troubleshooting, testing, and refinements based on data or scientific principles.	Clear evidence of troubleshooting, testing and refinements.			Some evidence of troubleshooting, testing and refinements.	Little evidence of troubleshooting, testing or refinement.
Construction of Raft	Structure functions extraordinarily well, holding up under atypical stresses.	Structure functions well, holding up under typical stresses.			Structure functions pretty well, but deteriorates under typical stresses.	Fatal flaws in function with complete failure under typical stresses.
Material Usage	Appropriate materials were selected and creatively modified in ways that made them even better.	Appropriate materials were selected and there was an attempt at creative modification to make them even better.			Appropriate materials were selected.	Inappropriate materials were selected and contributed to a product that performed poorly.
Explanation of Content	Explanations by all group members indicate a clear and accurate understanding of scientific principles underlying the construction and modifications.	Explanations by all group members indicate a relatively accurate understanding of scientific principles underlying the construction and modifications.			Explanations by most group members indicate relatively accurate understanding of scientific principles underlying the construction and modifications.	Explanations by several members of the group do not illustrate much understanding of scientific principles underlying the construction and modifications.
Raft Building Procedure	4	3			2	1
Procedure	Procedures are listed in clear steps. Each step is numbered and is a complete sentence.	Procedures are listed in a logical order, but steps are not numbered and/or are not in complete sentences.			Procedures are listed but are not in a logical order or are difficult to follow.	Procedures do not accurately list the steps of the experiment.
Measurements and Materials	All measurements and materials are shown and the results are correct and labeled appropriately.	Some measurements and materials are shown and the results are correct and labeled appropriately.			Some measurements and materials are shown and the results labeled appropriately.	No measurements are shown OR are inaccurate or mislabeled. OR materials are specified
Spelling	One or fewer errors in spelling, punctuation and grammar in the report.	Two or three errors in spelling, punctuation and grammar in the report.			Four errors in spelling, punctuation and grammar in the report.	More than 4 errors in spelling, punctuation and grammar in the report.
Clarity of instruction	Procedures appear to be replicable. Steps are outlined sequentially and are adequately detailed.	Procedures appear to be replicable. Steps are outlined and are adequately detailed.			All steps are outlined, but there is not enough detail to replicate procedures.	Several steps are not outlined AND there is not enough detail to replicate procedures.
