Problem Statement

1	2	3	4
>Statement of problem is irrelevant or erroneous >Limited or no relevant explanation	>Problem partially identified with partial validity >Limited relevant explanation	>Problem sufficiently identified with some validity >Basic relevant explanation	>Problem is appropriately identified >Precise, clear and relevant explanation

Experimental Hypothesis

1	2	3	4
>Unreasonable association between problem and predicted results >Results are not operationalized >Defends or challenges established knowledge >Scant use of scientific concepts and vocabulary	>Association between problem and predicted results >Made attempt to operationalize key variables >Hypothesis has some relationship to established knowledge but is not supported >Scientific concepts and vocabulary used, but contains errors	>Reasonable association between the problem and the predicted results >Key variables are operationalized >Hypothesis has a reasonable relationship with established knowledge; this relationship is generally supported >Scientific concepts and vocabulary used without significant error	>Association between the problem and the predicted results is direct and relevant >All variables are clearly operationalized >Hypothesis clearly refutes or defends established knowledge and is fully supported >Student demonstrates facility in the use of scientific concepts and vocabulary

Experimental Design

1	2	3	4
>Design is not relevant to the hypothesis >List of materials and controls incomplete >Some procedural components generally described but are not replicable >Safety concerns are not specified, are irrelevant or are not appropriate to the experiment	>Design has general relevance to the hypothesis >List of materials and controls is nearly Complete, missing at least one important item >Description makes it possible to replicate the experiment if researcher makes some inferences >Safety concerns miss at least one important consideration; procedures will result in some risk to student safety if not revised	>Design is adequate to test the hypothesis >List of materials and controls is complete and some description provided >Description makes it likely that the experiment can be reliably replicated >All major safety concerns are adequately addressed; procedures adopted are likely to produce a safe experiment -- some further refinement could minimize possible discomfort to the student	>Design is a well-constructed test of the stated hypothesis >List of materials and controls is complete and Thoroughly described >The description of the experiment is complete, insuring that it can be replicated >Safety concerns are fully addressed and procedures for conducting the experiment insure that there is little or no risk of safety or discomfort to the student

Data Collection & Analysis

1	2	3	4
>Data are inaccurate >Data are haphazardly recorded >Data table missing	>Most data are collected but checks are not placed on measurement to insure accuracy >Data are recorded in a manner that threatens reliability >Data table incomplete or contain inconsistencies	>All significant data measured with some checks placed on measurement for accuracy >Data recorded effectively >The data table is relevant to the task requirements	>All significant data measured, checks are placed on measurements for accuracy >Data recorded effectively and efficiently >The data table well-designed to the task requirements

Data Display

1	2	3	4
>Graph form inappropriate >Data points missing or incorrect >Inappropriate labeling >Intervals inappropriate	>Graph form is appropriate >All data points included, some inaccurately plotted >Labeling lacks clarity >Intervals are appropriate	>Graph form is appropriate, multiple graphs used as warranted >All data points included and accurately plotted >Labeling clear >Intervals appropriate >Graph visually designed to assist reader	>All graph forms are appropriate, multiple graphs used as warranted >All data points accurately plotted >Labeling clear >Intervals appropriate >Graph visually compelling, highlights conclusions of the study

Conclusion

1	2	3	4
>Inconclusive, or conclusion not warranted by data analysis	>Conclusion too general or over-reaches the data analysis >Conclusion uses the language of the experiment but does not translate conclusion to its relevance to the original problem	>Conclusion precise, related to the hypothesis >Conclusion uses operational terms of the experiment and attempts to translate the conclusion to make it relevant to the original problem >The conclusion related to general interest and other studies	>Conclusion precisely stated, relates directly to support or non-support of the hypothesis >Conclusion uses operational terms and suggests how the conclusion has relevancy in resolution of the original problem >Conclusion relates the study to general interest, other studies that have been or could be conducted
