How algebra helps us model the invisible decay of radioactive atoms
In short: This video demonstrates how exponential and logarithmic functions allow us to track physical phenomena like radioactive decay. It moves beyond basic equations to show how math tackles significant questions about the natural world.
The lesson uses the decay of cesium-137 as a practical application for Algebra II concepts. By studying these functions, students learn to model how quantities change over time at rates that are not linear.
This transition from Algebra 1 to Algebra 2 represents a shift toward solving 'big questions' of the universe, including complex numbers and conic sections, using adaptive technology designed to identify specific learning gaps.
