Biology is a life science, investigating the interactions of living things with living and non-living factors in their environment. Aboriginal and Torres Strait Islander Peoples have different methods for taking care of the land and producing medicine. When communicating in science, it is vital to use concise language that is suitable for the specific audience. When developing a research question you first must decide on the methodology because this can determine the style of the question. Maintaining a logbook is an essential requirement for scientific investigations. Key science skills are used in student investigations. Qualitative data is non-numerical data, whereas quantitative data is numerical data. Graphs are used to show relationships between variables. Precision, accuracy, repeatability, reproducibility and validity are concepts that must be used to evaluate the data and the methodology of an investigation. Systematic errors are consistent and repeatable, and reduce the accuracy of the data. Random errors are unpredictable and uncertain, and reduce the precision of the data. Outliers should not be dismissed, but evaluated, investigated and accounted for. Ethical approaches include consequences-based, duty- and/or rule-based, and virtues-based. Ethical concepts include integrity, justice, beneficence, non-maleficence and respect. There are ten assessment task types for Outcomes 1 and 2 of Units 1 and 2. Unit 1, Outcome 3 is a scientific investigation and Unit 2, Outcome 3 is an analysis of a bioethical issue. Examinations are another form of assessment for Units 1 and 2, assessing key knowledge as well as the key science skills. Preparing for an exam requires organisation and effective revision strategies.
