| 1. [i] Images, sketches, or drawing [4] |
|---|
| +1 | open circuit |
| +1 | closed circuit |
| +1 | short circuit |
| +1 | quality point for high quality drawings |
| 2. [if] Image formatting [3] |
|---|
| 3 | image, sketch, or drawing that is clear and informative with correct labels OR image fully appropriate to laboratory, original, explanatory, captions as appropriate, and distinguishes bulb base components accurately |
| 2 | Sketch is clear and complete, only a minor issues such as a mislabel, unoriginal, or lack of a necessary caption |
| 1 | Sketch is confusing, unclear, not well done, or inappropriate image, image copied from Internet without citation of source |
| 3. [dc] Data tables content conductors [2] |
|---|
| +1 | electrical conduction data |
| +1 | heat conduction data |
| 4. [tc] Conductors table format and layout [3] |
|---|
| 3 | Clear, concise, well thought out, informative. Includes both electricity and heat, both clearly labeled. |
| 2 | Missing borders or other minor format inconsistencies, or missing either heat or electricity data, or confusing, or unclear, or uses two tables or other less efficient presentations such as text, or lack of appropriate labels makes single table unclear |
| 1 | Incomplete, runs off edges of page, lacks minimal margins |
| 5. [dΩ] Data tables content current versus voltage: ohms [3] |
|---|
| +1 | per amperage, voltage coordinate pair [(0, 0) is a theoretic construct and was not measured, therefore not counted in analysis. Typically discussed on lab hand-back.]
|
| 6. [tΩ] Table: current versus voltage |
|---|
| 3 | Clear, concise, well thought out, informative |
| 2 | Missing borders, or missing units, or other minor format inconsistencies, reversed column order in whole or part (values often reversed) (order should be current then voltage for graph slope to be resistance) |
| 1 | Missing both dimensions and units, unclear, confusing, poorly done, highly incomplete |
| 7. [g] Graph format [3] |
|---|
| 3 | Graphs xy scattergraph, correct axis labels, current versus voltage |
| 2 | Missing a label or other element, or reversed current (x) and voltage (y) axes |
| 1 | wrong graph type or other serious errors |
| 8. [a] Data analysis [7] |
|---|
| +1 | heat versus electricity conduction |
| +1 | linearity analysis |
| +1 | slope |
