This document outlines activities for teaching students about acid-base reactions including demonstrations and experiments to engage students and help them explore and explain concepts. It discusses using red cabbage indicator paper to determine if solutions are acids or bases. Students would then use pH probes to measure temperatures changes during neutralization reactions to determine if they are endothermic or exothermic.
