IB Physics HL Internal Assessment Example

What effect does different temperatures have on the electrical resistance of a nichrome wire, and how far do experimental departures from theoretical calculations reflect limitations in the temperature coefficient of resistance model?HL

Official IB Result

IB Grade: 7

Criteria A: Research Design

6/6

Criteria StrandsPro

A.1Research question context

Excellent

A.2Methodological considerations for collecting data

Good

A.3Methodological considerations

Good

Criteria Feedback

The student posed a focused research question that clearly identifies the material, variables, and theoretical comparison.
The student placed the investigation in a relevant physics context by explaining why nichrome is suitable and how the TCR model applies.
The student's method includes several thoughtful controls, repeated measurements, and a generally reproducible procedure.

The justification for some design choices is incomplete, especially the use of water temperature as a proxy for wire temperature.
Some important methodological decisions, such as temperature spacing and the treatment of self-heating, are stated more than they are fully explained.
A few details would still need tightening for full reproducibility, including the exact temperature-maintaining procedure and clearer standardization of equilibration conditions.

Criteria B: Data Analysis

5/6

Criteria StrandsPro

B.1Communication of data recording and processing

Excellent

B.2Consideration of uncertainties

Moderate

B.3Data processing quality

Poor

Criteria Feedback

The student's raw data are organized clearly and consistently, making the measurements easy to trace.
The student communicates the processing route from voltage and current to resistance in a way that is mostly understandable.
The student shows awareness of uncertainty and includes several relevant processed quantities rather than only raw readings.

The uncertainty treatment is incomplete, especially because temperature uncertainty and repeat-spread are not properly incorporated.
Some processing steps contain mistakes or inconsistencies, including the theoretical resistance calculation and the reporting of the fitted relationship.
The graphing and presentation of processed results would be stronger with uncertainty bars and a clearer regression statement.
