Finding Atomic Weight Using Matrices

Activity Overview

Students are introduced to the key concepts of solving Linear Systems through the use of matrices. They will also look at the relationship between one equation and another equation. Later they will be exposed to multiple methods for using matrices to solve complex systems.

Before the Activity

This investigation offers many possible extensions depending on the level of the students. This investigation is most appropriate for Algebra II and Pre-Calculus students. The investigation has a direct application to chemistry.
Teacher should spend some time practicing this investigation with the calculator in advance of presenting it themselves.

During the Activity

This investigation is intended to be teacher-led. This lesson is best presented after the students have a general understanding of matrices and matrix operations.
