Reflection: Developing a Conceptual Understanding The Energy of Phase Changes - Section 3: Explain


As I presented notes to my students I noticed several things.

  1. Within the notes I did not give good examples in terms of significant figures, with several only having 1 significant figure so students would be rounding their answers a lot.  I will make sure to change this for next year.
  2. The video questions were hard to get from this one video.  I will try to find a better phase change video for students to better visualize what happens during phase changes with the particles and when temperature increases or remains constant.
  3. The amount of information in this set of notes was a little bit overwhelming for students.  For next year I will move the concept of enthalpy to the previous notes on energy diagrams so that there is less content in these notes.

The Energy of Phase Changes

Unit 5: Unit 6: Energy
Lesson 4 of 9

Objective: Students will be able to explain how energy plays a role in phase changes and be able to perform calculations using latent heat of fusion and vaporization through taking notes, working with partners, watching a video, performing a lab, and answering practice questions.

Big Idea: The phase of matter depends on the energy of the particles, and phase changed require either the absorption or release of energy.
