Lesson Plan: Single Displacement Reactions with Test Tube Diagrams
In this lesson students will perform and analyze two single displacement reactions and prepare and manipulate Test Tube Diagrams to depict the activity at the molecular level. Using manipulatives representing individual ions, atoms and molecules for the various reactants and products, they will accurately represent species in the solid, gaseous and aqueous states by correlating the Test Tube Diagram to the complete ionic equation for each reaction. They will determine the reactants and products responsible for color, as well as identify which species is oxidized and which is reduced.
