Data & Results The Evidence
3 Well written paragraph(s) introducing reader to the data presented and referring to the figures and tables ?
3 Data presented in table form for all solvents (1 or several tables). Include captions ?
3 Ln (Ksp) vs. 1/T plot with fit, labels, and caption ?
3 ?G vs. T plot with fit, labels and caption ?
3 ?H and ?S determined from the above plots. Compare in general sense to energetics and entropy expectations in the dissolution process [Check – some may put this in the discussion section] ?
3 s vs. T 3 plots of water, 1m, and 2m for each solvent ?
3 Equations presented as necessary to follow the transition from data to results in logical progress. ?
deduction (-2) Students that did not attend lab must identify source of data and make it clear they did not measure it.
3 Overall quality. Section is mostly text. This section is a narrative of the data. Allows readers to easily follow the data and validate its accuracy. ?
0 24 Data & Results Total ?
Discussion & Conclusion The Claim
3 Do solubilities at constant temperature follow simple pattern. Compare with Theory/expectations ?
3 Does it seem to matter which common ion is present in the solvent? Depends on results obtained but shouldn’t matter ?
3 Is KNO3 solubility behavior different in NaCl – describe. (depends on results) ?
3 A detailed and specific discussion of the results and uncertainties.
3 Describes if the evidence supports the scientific claim or conclusion.
3 Provides additional evidence that supports claim. (literature)
3 Is able to identify assumption and uncertainties in equipment and propagation of uncertainties through calculations
3 Describes how these uncertainties impact the final answer (too high/too low/why?)
3 Discusses if the experiment worked well and describes how the design of the experiment or their execution of the experiment could be improved.
3 Correctly state if hypothesis is supported or not, Revised hypothesis if necessary that fits evidence.
