rates & equilibrium

Unit 7 Overview

Students look at ways to speed up and slow down reactions and how to impact equilibrium equations. Students begin by exploring the rates of situations that are familiar to many of them: cooking. They rank the rates of cooking eggs depicted in different pictures. Once they get the actual cooking times they are expected to explain using their own understanding of why these rates are different. Once they identified the parameters associated with rate change, they design an experiment to test these factors using chalk and acid. This mimics how increasingly acidic oceans will have impacts on calciferous creatures in the ocean. We then discuss the equilibrium associated with ocean acidification. Students use a model of equilibrium to develop their own definition of the term. Students then predict how different equilibrium reactions and test them in a lab. This will be brought back to ocean acidification and later tied to biological systems.
