Phase Changes

West Haven Public Schools

Unit Planning Organizer

Subject:   Integrated Science                                      

 Grade:    10

Unit 7:  Phase Changes (9.1)                                   

 Pacing:   2 weeks

Essential Question(s):

  1. How does a thermometer work?
  2. What determines whether or not a phase change occurs?
  3. Where does energy come from and where does it go once we use it?

 

Big Idea(s):

  1.  Kinetic Theory explains that molecules move faster and spread apart as a substance’s thermal energy increases
  2. Energy absorbed by or released from a system may change the phase of a substance
  3. Most available energy on Earth comes from the sun. Energy cannot be created or destroyed; however, it can change forms

 CT State Standards (includes West Haven’s “Priority” GLES’s in BOLD and “Supporting” Standards)

Describe the motion of atoms and molecules during phase changes

Analyze and interpret phase change diagrams

Compare and contrast deposition, evaporation, and sublimation

Compare and contrast freezing, melting, boiling, and condensation points

Compare and contrast conduction, convection and radiation and provide real world examples of each.

Explain the relationship between temperature and kinetic energy

Discuss the role of thermal capacity

Understand and explain that most of our energy comes from the sun

Describe the Law of Conservation of Energy as it relates to the Earth.
