- Developing a statement of the purpose written as a hypothesis linked to a scientific concept or idea - Using a method that describes: a range for the independent variable, the measurement of the dependent variable and the control of some other key variables - Collecting, recording, and processing data relevant to the purpose of the investigation - Interpreting and reporting on the findings - Reaching a conclusion based on the student’s processed data which is relevant to the purpose of the investigation - Identifying and including relevant findings from another source. |
- Using a method that describes: a valid range for the independent variable, the valid measurement of the dependent variable and the control of other key variables with consideration of factors such as sampling bias and sources of errors - Collecting, recording, and processing data which enables a trend or pattern (or the absence of a trend or pattern) to be determined - Reaching a valid conclusion based on the student’s processed data which is relevant to the purpose of the investigation - A discussion of the biological ideas relating to the investigation that is based on the student’s findings and those from other source(s). |
- Justify the choices made during the sound investigation, ie evaluating the validity of the method or reliability of the data and explaining the conclusion in terms of the biology ideas relevant to the investigation. |
