Content Focus

Students are introduced to the quantitative nature of chemistry. Chemists must be able to quantify reactions in order to make predictions about yields and communicate with specific audiences for specific purposes using nomenclature, genres and modes unique to the discipline. Using the mole concept, students will have the opportunity to select and use appropriate mathematical representations to solve problems, make predictions and calculate the mass of reactants and products, whether solid, liquid or gas.

Students further develop their understanding of the universal language of chemistry. They are introduced to the idea that science is a global enterprise that relies on clear communication, international conventions, peer review and reproducibility.

Working Scientifically

In this module, students focus on designing and evaluating investigations that enable them to obtain quantitative data to help them solve problems related to quantitative chemistry. Students should be provided with opportunities to engage with all the Working Scientifically skills throughout the course.

Biblical Perspective

God is the author also of both the chemical world and of logic.  His creation totally depends upon God not just for its origin but also for its continued existence, as the Bible says, "He upholds the universe by the word of his power " (Hebrews 1:3).  The Bible speaks clearly of an all-knowing, all-powerful God who leaves nothing to chance: "The lot is cast in the lap, but the decision is wholly from the Lord" (Proverbs 16:33).  A study of quantitative chemistry enables us to better appreciate the wonderful world that God has created, as well as the Creator Himself.  To make sense of a list of observations we next try to fit the observations to a simple mathematical formula.  This allows us to more easily describe, analyse and predict the results of a chemical reaction.
