Stoichiometry is one of the most important—and often most challenging—topics in Grade 11 chemistry. Students must combine chemical equations, mole conversions, molar mass and ratios in a single problem. Missing one step can affect the entire calculation. The good news is that most stoichiometry problems follow the same basic process. Once students understand the sequence […]
SCH3U Grade 11 Chemistry is often a student’s first course dedicated entirely to chemistry. It introduces abstract scientific ideas, mathematical calculations, laboratory investigations and new terminology — all at a considerably faster pace than Grade 10 science. Students who succeeded in earlier science courses may initially be surprised by the level of detail and problem-solving […]
Ontario’s MTH1W Grade 9 math course introduces students to a wide range of concepts, including algebra, linear relations, geometry, data, coding and financial literacy. It also asks students to solve unfamiliar problems, explain their reasoning and connect mathematics to real-life situations. For many students, the greatest challenge is not a single unit. Difficulties often arise […]
