Procedure: Directions: Design an investigation to answer the following question: “How is temperature effected as phase change occurs?” Develop each component of the investigation including a hypothesis, procedures, data analysis, and conclusion. Implement your procedure only when it has been approved by your teacher. 42
Phase Changes Activity #5-Everyday Reactions Question to be Investigated: What exothermic and endothermic reactions do you encounter on a daily basis? Objective: C5.4d Explain why freezing is an exothermic change of state. Teacher Notes: This is a structured inquiry project that should be done when students have a strong understanding of exothermic and endothermic reactions and heat flow. Real World Connections: Students are tying in real world examples of heat flow in systems. Source: Buthelezi, T. et al. Glencoe Science Chemistry Matter and Change, Columbus, OH: The McGraw-Hill Companies, Inc.,2008. Procedure: Student Directions: Think about two exothermic and two endothermic reactions or processes that you encounter in your everyday life. Record the following information: • a description of each reaction or process • the direction of heat flow • the change in the enthalpy of the system • change in enthalpy of the surroundings 43
