Investigation 6 (annotated)

1

PE: Personal engagement is assessed holistically. This investigation is appropriate for an IA and the student does an adequate job. However, it is also a standard high school lab, and the student's lack of input in the design, processing and presentation of the results, and the limited depth of understanding, earn the student a 2 level of achievement for PE.



2

CM: The report is nicely organized and flows well. Communication is assessed in a holistic way, so there is no single item to demonstrate this criterion.



3

EX: A thoughtful reflection.

EX: Minimal background information is given. The constant is defined as an invariant quantity to 10 decimal places.

EX: This is not appropriate here. The purpose of the IA to is determine the constant.

CM: The student does not mean this, but such a confusiondoes not affect the overall quality of this report.

EX: We know that the student will notperform the investigation in a vacuum. Morebasic research is needed.



4

EX: Ten Amperes is rather high for high school work butthe student is being careful.

AN: Uncertainties are missing for key values. Given the purpose of this IA, such informationwould normally be essential. For example, the ammeter is an analogue scale.



5

AN: Standard deviation is used instead of propagating uncertainties. This does not align withthe purpose of the IA. Also, there is a mismatch of significant figures with final values.

EX: We do not need to knowthe obvious.

AN: Missing units.



6

CM: Units "A" and missingunits for SD and mu(air) .



7



8

AN: An appropriate graph but no error bars, andintercepts to think about.

AN and CM: The student is wrong about proportionality.



9

EV: Again we see the weakness due to lack of deep understanding. Thepurpose of the investigation was to establish the constant for air, andprocessing uncertainties to see how accurate and precise one could get.

AN and EV: Now the student's attention goesto uncertainties.

EV: Yes, but Vernier's Lab Pro does do this.



10

EV: An appropriateobservation. This informationshould have been involved inthe data processing.

EV: No extensions are mentioned.



11

CM: Easy to followreferencing. HyperPhysics isan excellent resource.
