This week the grade 12 students finished their studies on complex numbers. They learned how to perform computations on complex numbers, and how to represent these values in Cartesian, polar, and exponential form. Most importantly though, was the understanding that complex numbers are just as “real” as real numbers are.
The AP Physics students worked on their first experiment of the year: an investigation of the behaviours of cans of soup with various consistencies, when rolled down ramps of varying inclinations. Students explored lab equipment such as sonic rangers to optimize the collection of data, which they will analyze to study the cans’ energy and fluid dynamics.
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.
