I developed this SIOP cooperative activity when my students were struggling with acids, bases, indicators, and pH calculations.
Students are given a question and its answer printed on cardstock. They read their question to a partner, wait for an answer and sign off on a checklist as to the partner's level of understanding. They trade questions and work their way through the room (hence, cocktail chatter). The questions cover hydroxide and hydronium ion concentrations, characteristics of acids and bases, indicators, etc.
This quick activity (15 minutes or less) made a huge difference for student understanding.
