Grade 10 Academic Science (SNC 2D1)Introduction to ChemistryWelcome to Chemistry!As we move forward through the chemistry unit, we will review concepts you covered ingrade 9, such as physical and chemical properties, pure substances, mixtures and chemicalchanges.We will also touch on new topics such as: why chemicals react, characteristics of chemicalreactions and how these reactions can be represented. We will also analyze various safetyand environmental issues related to chemical reactions and how chemical reactions can beused to address environmental challenges.Ensure that you take the time to learn the material, do the practice work, ask for help soonerrather than later and use the assessment checklist to ensure that all items that allassessments of your learning are completed and submitted.Good Luck!Page 3

Assessment ChecklistThroughout this course, we will use various assessment methods to provide “formativeassessment”. That is, assessment FOR and AS learning. These are used to provide feedbackand self reflection to improve your learning and understanding.However, some items are used as an assessment OF your learning. These are listed in thechart below. You should keep track of these items and ensure that all of them are completedand submitted on time according to the class expectations (see first day handout).ItemKeep inWorkbookor Hand-inTotalMarksHousehold SubstancesBook5Density WorksheetsBook4Bohr Diagrams and Ionic ChargesBook4Overall completion of Module 1Book4Hand-in10Book6Nomenclature QuizHand-in11Lab: Testing IonsHand-In10Bonding Gizmo (Ionic or Covalent)Hand-In8Overall completion of Module 2Book4Lab: Conservation of MassHand-In8Lab: Synthesis and Decomposition RxHand-In8Lab: Single and Double Displacement RxHand-In8PH GizmoHand-In8Lab: Acids and BasesHand-In8Book4Hand-InTBD------TBDAlien Periodic TableIonic Charges and Chemical FamiliesOverall completion of Module 3Big Idea Chemistry ProjectUnit TestPage 6DueDateYourMark
