2008 Grade 9 Science Exam Topic Review Sheet You know that it is the end of the year when… Exam Review Sheets start appearing! Here is a list of the topics that we covered during our studies of Chemistry, Biology and Physics this year. You will find this list very similar to the review sheets that were handed out before each test. Good News: Astronomy is NOT included on your final examination! (Although it will be part of the Summative…) Also note: You will be given a periodic table and an electrostatic series with your examination. Chemistry Review Topics 1. Physical properties and chemical properties Definitions and examples 2. Physical change and chemical change Definitions and examples Evidence for a chemical change Corrosion (definition, examples) and Combustion (definition, examples, fire triangle) 3. Particle theory of matter 4 postulates Particles and the states of matter (closeness, attraction, types of motion…) Particles and changes of state 4. Classification of matter Definition of matter Pure substances vs. mixtures (homogeneous mixtures vs. heterogeneous mixtures) Elements vs. compounds Molecules vs. atoms Definitions and examples 5. The symbolic language of chemistry – elements 32 symbols/elements Rules about using the symbols 6. Generating Gases in a chemical change Chemical properties involved in the gas tests (oxygen, hydrogen, carbon dioxide) 7. The symbolic language of chemistry – compounds Predicting scientific names eg. Calcium chloride Naming the elements in a compound Naming the numbers of atoms in a molecule 8. Making molecular models How many bonds can C, H, O, N, Cl form? Structural drawings Why is nitrogen unique Why build models? Relationship to combining capacity 9. Atomic structure 3 particle types – location, charge and mass Atomic number – definition, reading it from the periodic table Mass number – definition, reading it from the periodic table Standard atomic notation
