Chemistry 1.1 Carry out a practical chemistry investigation with direction
Achievement criteria
A practical chemistry 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
- collecting, recording, and processing data relevant to the purpose
- a conclusion based on interpretation of the processed data.
Achievement
- Carry out a practical chemistry investigation.
Achievement with Merit
- Carry out a quality practical chemistry 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
- the collection of data with consideration of factors such as sampling, bias, and/or sources of error
- collecting, recording and processing of 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 and evaluate a quality practical chemistry investigation.
- To evaluate means that you will justify the conclusion in terms of
the method used. Justification will involve, where relevant,
consideration of the:
- reliability of the data
- validity of the method
- chemistry ideas.
