Physics 3.1 Carry out a practical physics investigation with guidance, that leads to a mathematical relationship
Achievement criteria
The criteria for each level of achievement is based on your ability to collect data, process data, and present the evidence of the experiment, with the method and conclusion, in a written report.
Achievement
- Carry out a guided investigation that leads to a non-linear mathematical relationship.
- Evidence for Achievement may include:
- data relevant to the aim based on the manipulation of the independent variable and the consideration of other variable(s) that could affect the results
- uncertainties in raw data appropriate to the measurement
- a linear graph, including an error line, based on the data and relevant to the aim
- a conclusion that links to the aim and is drawn from information calculated from the linear graph.
Achievement with Merit
- Carry out a guided investigation that reliably leads to a non-linear mathematical relationship.
- For Achievement with Merit, evidence may include:
- accurate data relevant to the aim based on the manipulation of the independent variable over a reasonable range and number of values
- a description of the control of other variable(s) that could significantly affect the results
- the use of techniques to improve the accuracy of measurements
- appropriate uncertainties in raw and plotted data
- a linear graph with error bars and appropriate error line, based on sufficient data, relevant to the aim
- a conclusion that is relevant to the aim, based on the data, and is drawn from information calculated from the linear graph, including a processed uncertainty
- a discussion that evaluates the quality of the results.
Achievement with Excellence
- Carry out a guided investigation that reliably and validly leads to a non-linear mathematical relationship.
- For Achievement with Excellence, evidence may include:
- accurate data relevant to the aim based on the manipulation of the independent variable over a reasonable range and number of values
- a description of the control of other variable(s) that could significantly affect the results
- the use of techniques to improve the accuracy of measurements
- uncertainties appropriately calculated in all processed data
- a linear graph with error bars and appropriate error line, based on sufficient data, relevant to the aim
- a conclusion that is relevant to the aim, based on the data, and is drawn from information calculated from the linear graph, including processed uncertainty
- information calculated from the linear graph is correctly rounded
- a discussion that shows critical thinking, evaluates and explains the validity of the results, and considers relevant physics theory.
