Identifying Ions

Grade 12 chemistry students completed a lab experiment that involved finding the ion composition of two unknown solutions. Students performed various qualitative tests on the solution, such as precipitate, flame, and ash tests. Using the results of these tests, they were able to determine the elements in the aqueous solution.

Badminton Regionals

This week, three TOPS students competed in the Toronto Regional Badminton tournament. Students competed against other schools in the district, vying for the chance to go to the city championships. All three students made it to the city championships and are excited to attend!


The grade 12 Algebra and Geometry class started their adventure into vectors. Students learned about vectors, dot products, their properties, and the steps to check if two vectors are orthogonal. These new topics enhance their existing mathematics knowledge and will be applied in greater complexity in the following units.  

AC Circuit Lab

Grade 12 AP physics students are working on their fourth lab of the year, which involves experiments that use alternating current. They have assembled a resistor-capacitor circuit, an inductor-resistor-capacitor circuit, a transformer, and a Helmholtz coil. Students are also simulating the fringe effects of two coils of wire to determine the magnetic field in three dimensions.
