Electrical Transformers

This week, students from Ms. Patrascu’s Grade 12 TOPS Physics class unearthed the mysteries behind electricity as they created a transformer in class. Students were able to witness a magnetic field induce a measurable charge by placing a solenoid in a current-carrying loop of wire. This process, which transforms alternating current to direct current, powers homes all across the world!

Acid-Base Titration

Is it sulfuric acid or is it hydrochloric acid? Is it nitric acid or could it be acetic acid? This week in Grade 12 chemistry, each student was given an acid at random. By titrating the acid with a base until it was neutral, students were able to perform calculations to determine the molar mass of the unknown acid.
