Exploring Thermal Energy and Phase Changes

Exploring Thermal Energy and Phase Changes

Learning Objectives

Understand the changes of state from solid to liquid to gas, energy transfer, particle motion, and thermal properties.

What do you already know about thermal energy and phase changes?

Changes of State

Describe the changes that occur when a solid melts to form a liquid, and when a liquid evaporates or boils to form a gas.

Particle Arrangement

Explain the arrangement and motion of particles in solids, liquids, and gases.

Energy Transfer

Describe how thermal energy transfer may take place by conduction, convection, and radiation.

Convection in Everyday Phenomena

Explain the role of convection in everyday phenomena.

Emission and Absorption of Radiation

Explain how emission and absorption of radiation are related to surface and temperature.

Reducing Unwanted Energy Transfer

Explain ways of reducing unwanted energy transfer, such as insulation.

Specific Heat Capacity and Latent Heat

Understand specific heat capacity, latent heat of fusion, and latent heat of vaporization.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
