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 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.
