The grade 12 chemistry students studied acid-base equilibrium. They completed two separate titrations using hydrochloric acid and acetic acid against a sodium hydroxide base. The pH values were recorded using a pH meter and Vernier LabQuest. The resulting titration curve was studied and the molar concentrations of the acids were determined.
The Marc Garneau co-ed volleyball team finished their last regular season game with a victory over Parkdale Collegiate Institute. The team trained in the mornings at 7:00am and after school until 5:00pm with a community coach. They will be moving on to the playoffs in the following week.
The grade 12 linear algebra class studied the linear dependence and independence of vectors. They generalized the definition to Nth dimensional space and attempted to use their new knowledge in geometric proofs using vectors. For their assignment, they submitted a problem set of 30+ formal vector proofs.
The grade 12 chemistry students studied factors influencing rates of reactions. During a lab, they mixed a thiosulfate solution with hydrochloric acid and timed how long it took for precipitate to form under different initial concentrations and temperatures.
