Chemistry 1.1 Carry out a practical chemistry investigation with direction
Achievement criteria
The level of achievement that you will reach is decided by the way you carry out a practical science investigation. Your investigation will involve planning, collecting, and processing the data, and interpreting your results.

Achievement
Carry out practical chemistry investigation, with direction.
A practical chemistry investigation will involve:
- developing a method to collect data
- identification of a range for the independent variable or sample
- measurement of the dependent variable or the collection of data with units
- collecting, recording, and processing data relevant to the purpose
- a conclusion based on the processed data.
Achievement with merit
Carry out an in-depth practical chemistry investigation.
An in-depth investigation will include:
- All criteria for achievement
- a valid range for the independent variable or sample
- sufficient repetition to show reliability of the data
- ways of controlling other variables that may have a significant effect on results
- the collection of data with consideration of factors such as sampling, bias, and/or sources of error
- techniques that increase the accuracy of the measured values of the dependent (and independent variable)
- collecting, recording and processing 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 chemistry investigation.
A comprehensive investigation will include:
- all criteria for merit
- justification of the choices made to increase the accuracy during the investigation
- justification of the conclusion in terms of the processed data and the purpose of the investigation
- links between the investigation findings and applicable chemistry ideas.
