Introduction (20 %)

Relevant terms and lab techniques are described or defined.

A connection is made between these terms and the specific lab investigation.

The lab purpose is clearly stated.

The above concepts are connected in a cohesive paragraph or two.

2.3

Hypothesis (5 %)

Is clear, concise and represents an appropriate educated guess.

Can be tested.

Has supportive reasoning for the prediction.

3.4

Procedure (10 %)

Is presented as a narrative (in paragraph form).

Describes the method of data collection or product design.

Mentions any equipment, chemicals and software used.

Is concise, but explained in enough depth that the experiment could be replicated.

Data/Data Analysis (25 %)

Data is organized/displayed in computer-generated tables and graphs.

Data display is visually appealing, easy to follow, and reflects relevant patterns/trends.

Data includes qualitativeobservations that follow the table of quantitativevalues.

Quantitativevalues are presented with appropriate units and correct # of significant digits.

Calculations are shown with units and significant digits.

Data analysis is included, demonstrating important patterns or trends in personal & class data.

(this mayinclude: %-error, mean, median, mode, R2)

Conclusion (40%)

The purpose and hypothesis are revisited with a discussion of underlying presumptions (on

what chemical basis did you make your original hypothesis?)

The hypothesis is assessed (supportedor not) with a direct link to relevant data/findings.

Data analysis values (sec 4.6) are referred to in order to discuss precision and accuracy error.

Valid sources of error, including procedural sampling and measurement error, are discussed

Human error (speculated mistakes or calculation error) is NOT included as a valid source.

The cited error sources can be used to explain your results relative to the expected results. Recommendations are offered for future modifications/adjustments of the experimental

design based on the error sources.

Any assigned Lab Questions are answered.

The lab is tied in with other chemical applications (concepts or common everyday uses).

Relevant Chemical Themes (from class flowcharts) are discussed.

The discussion is focused, sequential, and eloquent.
