Session S63a (Wednesday, 9:30am, Wartik 107)

P692: A very cool investigation: A guided inquiry laboratory

Ryan Schoenborn (Bloomingdale High School, USA)

High school chemistry students often struggle with concepts related to thermochemistry and enthalpy. The misconceptions related to heat and temperature are well documented. This lab, developed as part of the Target Inquiry Program at Grand Valley State University, requires students to use thermochemistry to determine how many disposable ice bags are required to induce therapeutic hypothermia for an accident victim. Using a guided inquiry format, this lab helps students understand the difference between heat and temperature as they investigate the concept of enthalpy of dissolution. Facilitation tips and sample student data will be provided.
