REVISION / SUPPORT

Planning

A] A testable hypothesis is formulated independently and stated in a concise form. The nature of the problem is explained using relevant, detailed Biological knowledge, principles and concepts.

B] The choice of apparatus and materials is fully justified. It is clear how and why the number and types of measurements were chosen and they will generate useful, reliable results. The planned procedure describes how all the variables are to be controlled.

C] There is thorough assessment of the risks and the plan allows the investigation to be carried out safely and with due regard to living things and the environment where appropriate.

Implementing

A] Apparatus & materials are handled competently. A wide range of techniques are used with a high degree of skill.

B] The investigation is very well organised and carried out methodically with meticulous attention to safety at all times. Due consideration is given to the well being of living organisms and the environment.

C] Measurements are made to a high degree of precision and with attention to detail. Recordings are repeated and accurately linked to the hypothesis. All original raw observations are methodically and accurately recorded in a suitable table with headings and SI units.

Analysis

A] A high degree of competence is shown in the presentation and tabulation of raw and processed data. Appropriate graphs are carefully selected to display important trends patterns and comparisons directly related to the hypothesis. There should be no repetition and error bars or SD bars should be used as appropriate. SI units are used accurately at all times.

B] Trends and patterns in the data are clearly recognised and commented on. All apparent anomalies or inconsistencies are described.

C] Coherent, logical and comprehensive explanations of the results are given using carefully selected, appropriate Biological knowledge and terminology.

Evaluating

A] Variability of the results and any anomalies are used to assess how reliable and precise the experimental data is and the conclusions that have been drawn from them. The critical analysis shows an awareness of the tentative nature of the results of a single investigation.

B] Limitations of the experimental techniques employed, and their influence on the results, are discussed in detail. Proposed suggestions for further investigations would provide considerable additional evidence to support the conclusion or for the need to extend the enquiry.
