Explanation of Le Chatelier's Principle: Why Does It Work?

Created by

Chemistry students must be able to use Le Chatelier's Principle on equilbria and can usually successfully make predictions with it without understanding why it works. By setting up an equilibrium with varying concentrations and using the kinetic energy distribution to explain temperature effects, thePrinciple becomes more understandable. Effects of volume changes, surface areas, solids, catalysts, Keq and liquids are illustrated. Students can then apply the Principle in various situations. A 12

Physics can be fun and understandable to middle school students! This experiment is simple to set up and allows students to observe and measure motion and the effects of friction on a marble. This product starts with an introductory activity to convert friction into another form of energy by rubbing hands together. Students observe a demonstration of a marble moving on a smooth surface, like the classroom floor, and then the same marble moving on a material that increases friction. Repeated tria
