IB Biology SL Internal Assessment Example

What is the effect of simulated hot wind on the transpiration rate of five Australian native plants (River Red Gum, Kangaroo Paw, Grevillea 'Peaches and Cream', White Correa, and Common Fan Flower), as measured by a change in percentage loss ( %) in mass (g)?SL

A.3Methodology description

Criteria Feedback

The student places the investigation in a clear biological context and explains why the question matters.
The student's method is detailed enough that another student could broadly follow the procedure.
The student justifies some important design choices, such as using percentage mass change for different species.

The student's research question is a little imprecise in how it defines the dependent variable.
Some key controls are not explained well enough, especially the temperature and airflow at the leaf surface.
The selection and standardization of samples could be described more clearly to strengthen validity.

Criteria B: Data Analysis

B.1Communication of data recording and processing

Good

B.2Consideration of uncertainties

Poor

B.3Data processing quality

Poor

Criteria Feedback

The student presents the raw data in a reasonably organized way with units and repeated trials.
The student attempts multiple forms of processing, including percentage change, summary statistics, graphs, and statistical testing.
The student shows awareness that uncertainty matters by including balance precision and error bars.

There are some important inconsistencies between the raw data and the processed values.
The student's uncertainty treatment is not always appropriate for the quantities being analysed.
The communication of the results is not consistently precise, especially where labels, calculations, and interpretations do not always align.
