The grade 12 chemistry class conducted an experiment to find the rate law of the reaction between sodium thiosulfate and hydrochloric acid. Students determined the reaction rates by observing how quickly the mixture became cloudy. A second experiment was completed to determine the effect of temperature on the reaction rate as well.
TOPS students participated in MGCI’s annual Winterfest Activity Day to relax after a busy semester. Winterfest offers students the opportunity to try fun, new activities with their peers. Some of the options available this year were rock climbing, skiing, a downtown scavenger hunt, and a visit to the Toronto International Film Festival.
The grade 12 chemistry class performed two titration experiments using a standardized solution of potassium iodate they had prepared. Based on the data gathered, students applied their stoichiometry knowledge to determine the concentrations of unknown sodium thiosulfate and iodine solutions.
The grade 12 AP physics presented their summative project on Friday. Students built one pixel cameras that could scan a 300 pixel by 300 pixel image in under 10 minutes. Successful groups also attempted to produce a coloured image using filters.
