This week, the grade 9 math class continued their study of money, exploring the intricacies of compound interest. Students learned about converting between nominal and effective interest rates, calculating changing compounding periods, as well as instantaneous compounding. They will soon go on to study logarithms.
This week, the grade 9 science class continued their study of electricity and circuits. Students drew circuit schematics including electrical components like resistors and switches. They explored electric current, potential difference, and resistance in circuits. They will soon go on to study the differences between series and parallel circuits.
