ST JOHN’S GRAMMAR STAGE 1 CHEMISTRY
ASSESSMENT OVERVIEW – SEMESTER 1 2006
1. Learning outcomes
At the end of the program in Stage I Chemistry, students should be able to:
 manipulate apparatus and record observations in chemical experiments;
 design investigations to test chemical hypotheses;
 obtain information about chemistry from a variety of sources;
 demonstrate knowledge and understanding of chemical concepts;
 analyse and draw conclusions from chemical data;
 develop solutions to chemical problems;
 use knowledge of chemistry to make informed personal, social and
environmental decisions;
 communicate ideas and reasoning, using chemical terms and conventions.
2. Assessment
Assessment in Stage I Chemistry consists of the following assessment components
and criteria for judging performance:
Assessment Component 1: Practical Work
Criteria:
experimental design skills
 identify the purpose of a given experiment;
 identify the independent and dependent variables;
 identify factors that need to be held constant;
 describe the procedure to test a hypothesis.
practical skills
 following instructions accurately and safely;
 recognising and responding to hazards;
 manipulation of apparatus;
 making accurate and honest observations;
 cooperation with others.
presentation
 choice of format for the recording and presentation of data;
 correct use of chemical terms and units;
 logical presentation of information.
interpretation and evaluation
 analysis, interpretation and evaluation of an experiment and suggestions for
improvements;
 identification of sources of error;
 describing the pattern of results and drawing valid conclusions.
Assessment Component 2: Tests
Criteria:
knowledge and understanding
 correct use of chemical terms and units;
 use of chemical terms and units in describing and explaining concepts and
processes;
 logical sequence of information in students’ work;
application
 appropriate selection of chemical information to address problems and
unfamiliar situations;
 application of knowledge of chemistry to problems and unfamiliar situations;
 use of knowledge of chemistry to make personal and informed social and
environmental decisions.
analysis
 drawing valid conclusions from chemical data;
 evaluation of the reasonableness of the solution to a problem
Assessment Component 3: Assignment
Criteria
research skills
 use and documentation of sources;
 analysis of sources for relevance, bias and credibility.
understanding
 correct use of chemical terms and units;
 effective use of chemical terms and units in describing and explaining
concepts and processes;
 sequencing information in a logical manner.
application
 application of knowledge of chemistry to problems and unfamiliar situations;
 use of a knowledge of chemistry to make personal and informed social and
environmental decisions;
 discussion of the impact of human practices and decisions on the environment;

identify and discuss alternative points of view on chemical issues.

4. Assessment Grades
The SACE grade will be based upon summative tasks only, with tests weighted to
50%, practicals 25% and assignments 25%.
The “Fermentation” practical will form part of a practical portfolio, which will be
assessed summatively.
The school assessment grade will be based upon tests weighted to 55%, practical
reports to 20% and assignments to 25%.
The exam grade will be shown as a separate grade at the end of the semester.
The SACE Deadlines Policy will be strictly adhered to.
