Which One Doesn't Belong - Energy and Chemical Reactions

The Which One Doesn't Belong - Energy and Chemical Reactions Concept Builder targets a learning goal in which students relate endothermic and exothermic reactions to a variety of representations. Each question has the same format: three to four representations are presented and learners must identify the one representation that is not like the others. Representations include chemical equations with an energy term, energy level diagrams, system-surroundings diagrams, information about ∆H, and verbal descriptions of temperature changes, energy levels, and heat flow. There are a total of 36 questions in this Concept Builder. They are organized into 12 different Question Groups and spread across the three difficulty levels. Question-specific help is provided for each of the 12 situations. Questions in the same Question Group include the similar types of representations. The built-in score-keeping makes this Concept Builder a perfect candidate for a classroom activity.
