A room temperature first aid pack rapidly becoming cold serves as the investigative phenomenon for this series of investigations. Students investigate physical and chemical changes in matter that result in the absorption or release of thermal energy. Using a calorimeter containing a known mass of water, student groups measure the change in temperature of the water caused by dissolving 2 salt compounds. The changes in temperature are used to calculate the heat of solution for each salt. In a second investigation, students measure energy changes that occur in a combustion reaction. Through these investigations students are tasked with making sense of chemical and physical processes to answer the driving question, “Why do some changes in matter result in a change in temperature?”

Time Requirement
Total, 120 minutes. Teacher prep, 30 minutes. Pre-lab as homework. Two investigations, 60 minutes. Assessment, 30 minutes.

Digital Resources
Includes 1-year access to digital resources that support 3-dimensional instruction for NGSS. Digital resources may include a teacher manual and student guide, pre-lab activities and setup videos, phenomenon videos, simulations, and post-lab analysis and assessments.
