Students used exothermic and endothermic salts to design prototypes of items that would heat or cool upon the salt dissolving, including a cooling headband (seen here) and and infant bottle warmer. This group's final report is linked below as well and shows an organized and well thought out product proposal, including interpreted data sets.

These are "A+ Explanations" that small groups wrote for AP free response questions and presented to the class. The instructions they were given are below: A+ Explanations Must: -Include step-by-step work and/or labeled diagrams where needed -Have a “why” for every “what” -Use academic language and vocabulary from the class A+ Explanations Might: -Use arrows, words, or different colors to connect explanation to answer

Students solved AP free response questions as a group, put their responses on a poster, and present to the class. These posters were hung up alongside explanations from other classes to showcase different ways to solve and explain problems. Both of these posters show clear explanations, but organized in different ways.
