Physics 1.1 Carry out a practical physics investigation that leads to a linear mathematical relationship, with direction
Achievement criteria
A practical physics investigation will involve:
- a statement of the purpose – this may be an aim, prediction, or hypothesis based on a scientific idea
- identification of a range for the independent variable or sample
- measurement of the dependent variable or the collection of data
- a method that can be followed
- collecting, recording and processing data relevant to the purpose
- identifying the trend and relationship between the variables
- a conclusion based on interpretation of the processed data.

Achievement
- Carry out a practical physics investigation. This involves:
- A method that outlines the basic steps to collecting the data
- Identifying a range and number of values
- Collecting the primary data, with correct units
- Drawing a relevant graph, based on the data
- Identifying the trend from the graph.
Achievement with merit
- Carry out an in-depth practical physics investigation.
- The method of your investigation will include describing:
- a valid range for the independent variable or sample
- a description of and/or control of other variables
- techniques used to improve accuracy of the measured variables
- the collection of data with consideration of factors such as sampling, bias, and/or sources of error
- collecting, recording and processing of data to determine the trend and relationship between the variables.
- a valid conclusion based on interpretation of the processed data that links to the purpose of the investigation and identifies the equation of the relationship.
Achievement with excellence
- Carry out a comprehensive practical physics investigation.
- Justifying the accuracy improving techniques used
- Justifying the limits to the independent variable
- Justifying why a variable needs to be controlled
- Link a physics idea and the investigation findings
- Reliability of the data and validity of the method.
