Innovating Science® - Equilibrium and Le Chatelier's Principle

Students will investigate equilibrium and Le Chatelier's principle through four different experiments. They will apply various stresses to different chemical systems at equilibrium, then use their understanding of Le Chatelier's principle to explain their results. Kit contains enough material for 15 groups. Teacher's Guide and Student Study Guide Copymasters are included.
