Biology 1.1 Carry out a practical investigation in a biological context, with direction

Achievement criteria

The level of achievement that you will reach is decided by the way you carry out a practical investigation. Your investigation will involve planning, collecting and processing the data, and evaluating your results.

On this page: Achievement | Achievement with Merit | Achievement with Excellence

Achievement

• Carry out a practical investigation in a biology context, with direction will involve:

• developing a method with sequential steps for collecting data.  The collection method will include:
• identification of a range for the independent variable or sample (at least three values)
• measurement of the dependent variable (or the collection of field data) with units

• collecting, recording and processing primary data relevant to the purpose. The raw data must be within a range of values feasible for the context.
• reaching a conclusion based on interpretation of the processed data.

Achievement with merit

• Carry out an in-depth practical investigation in a biology context, with direction means the method is valid, the data is reliable and the conclusion is valid.  This will normally involve:
• a statement of the purpose written as a hypothesis.
• a method that includes:
• a valid range for the independent variable (or sample);
• a description of, and where possible control of, other significant variables that may affect the results;
• accurate measurement of the dependent variable (or collection of field data) with units and consideration of factors such as sampling bias, and/or sources of error
• collecting, recording, and processing of data to enable a trend or pattern (or absence) to be determined
• a valid conclusion based on interpretation of the processed data that links to the purpose of the investigation.

Achievement with excellence

• Carry out a comprehensive practical investigation in a biology context involves:
• Justifying the choices made during the in-depth investigation ie
• Evaluating the reliability of the data
• Or evaluating the validity of the method
• AND explaining the conclusion in terms of applicable biological ideas.
