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. 3. Timeline for Summative Tasks Topic Summative Task Approx. week ending Materials and Particle Theory Poster – “An Everyday Chemical” Term 1 week 3 Particle Theory, Atomic Structure, Periodic Table, Equations Test Term 1 week 5/6 Atomic Structure Essay – “Historical Development of Models of the Atom” Term 1 week 6 Metallic and Ionic Bonding Test Term 1 week 10 Covalent Bonding Test Term 2 week 3 Organic Chemistry Experiment Design Fermentation Term 2 week 5 Organic Chemistry Test Term 2 week 7 Exam Term 2 week 8 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. 5.
