Expectations Overall Expectations: CHV.01P demonstrate an understanding of chemical reactions and the symbolic systems used to describe them; CHV.02P investigate chemical reactions encountered in everyday life and their practical applications; CHV.03P demonstrate an understanding of how chemical reactions relate to technological products and processes commonly encountered in everyday life. Specific Expectations: CH1.01P recognize the relationships among chemical formulae, composition, and names; CH1.02P demonstrate an understanding of chemical reactions, including conservation of mass, and their representation through balanced chemical equations; CH1.03P describe, using their observations, the reactants and products of a variety of chemical reactions, including synthesis, decomposition, and displacement reactions (e.g., the burning of magnesium, the production of oxygen from hydrogen peroxide, the reaction of iron in copper sulphate); CH1.04P describe qualitatively, using their observations, how factors such as heat, concentration, light, and surface area can affect rates of chemical reactions; CH1.05P classify substances as acids, bases, or salts based on their characteristic properties (e.g., reactions with indicators and with metals), names, and formulae (e.g., HCl, NaOH, NaCl); CH1.06P demonstrate an understanding of neutralization through investigation of simple acid-base reactions; CH1.07P describe how the pH scale is used to identify the concentration of acids and bases; CH1.08P name and write the formulae for common ionic and molecular compounds (e.g. H2SO4, NaNO3, CO2, NaOH). CH2.01P through investigations and applications of basic concepts select and use appropriate apparatus, and apply WHMIS safety procedures for the handling, storage, disposal, and recycling of laboratory materials (e.g., wear safety goggles and aprons; use proper techniques to handle, dispose of, and recycle acids, bases, and heavy metal ions; describe procedures to be followed in an emergency); CH2.02P through investigations and applications of basic concepts formulate scientific questions about acid-base neutralization reactions and outline experimental procedures to answer the questions; CH2.03P through investigations and applications of basic concepts demonstrate the skills required to plan and conduct practical experiments on acid-base neutralization reactions, and collect data using appropriate instruments and techniques in a safe and accurate manner (e.g., an experiment to neutralize a dilute solution of sodium hydroxide with dilute hydrochloric acid and extract the sodium chloride produced); CH2.04P through investigations and applications of basic concepts select and integrate information from various sources, including electronic, print, and community resources, to answer the questions chosen; CH2.05P through investigations and applications of basic concepts analyse the data and information gathered to clarify aspects of the questions chosen (e.g., data on changes in the acidity, fish populations, and clarity of Ontario’s small lakes over the years); CH2.06P through investigations and applications of basic concepts communicate the results of the investigation, using a variety of oral, written, and graphic formats (e.g., use molecular models to represent chemical reactions); CH2.07P use the pH scale to determine the acidity or basicity of some common household substances (e.g., vinegar); CH2.08P conduct experiments to determine the factors that affect the rate of a chemical reaction (e.g., temperature, surface area of a solid, concentration of a solution); CH2.09P represent simple chemical reactions using word equations, balanced chemical equations, and, where appropriate, molecular models. CH3.01P use scientific nomenclature to identify common consumer products (e.g., identify ingredients in food products or cosmetics from the labels); CH3.02P investigate applications of acid-base reactions in common products and processes (e.g., compare the effectiveness of different brands of antacid tablets by quantitative analysis; prepare soap from lard and sodium hydroxide and compare its lather formation with that of commercial soaps); CH3.03P relate chemical reactions (including the rates of reactions) to familiar processes encountered in everyday life (e.g., acid-base reactions in film processing, food processing, fabric and hair dyeing, agriculture, wine making, pulp-and-paper and mineral processing) and identify careers that require knowledge of such processes (e.g., environmental engineering, swimming-pool maintenance); CH3.04P research the methods of chemical disposal used in Canada and the environmental and individual health and safety consequences of inappropriate disposal methods (e.g., examine the effects of dumping car batteries, tires, plastics, paints, or metals in landfill sites). Assignment Assignment Design a WHMIS poster illustrating the dangers of three household chemicals found in your home. Include information regarding exposure, spills, storage and reactivity. choose one of the following topics: food spoilage corrosion of metal surfaces oil spill in water forest fires Determine the factors affecting these reactions.
