Featured in PASCO’s Physics through Inquiry Teacher Guide
Features over 30 inquiry based labs covering the core topic areas of mechanics, electricity and magnetism, optics, thermodynamics and more.
Use a stainless steel temperature sensor to observe physical changes in a system undergoing a phase change.
- Understand that adding thermal energy to a substance does not necessarily increase the substance’s temperature.
- Explore the idea that the “internal energy” of a substance is the sum of the average kinetic energy (temperature) and potential energy of the molecules in that substance, where the potential energy is associated with the phase or state of matter in which that substance exists.
- Understand that any transfer of heat during a phase change will produce only the phase change without changing the temperature of the substance.
Students gain experience conducting the following procedures:
- Observing physical changes in a system undergoing a phase change.
- Relating observations of a phase change to features of a graph.
- Identifying and annotating important features of a Temperature versus Time graph.
