Heat Transfer: How Does Heat Move?

Heat Transfer: How Does Heat Move?

Learning Objective

At the end of the lesson, you will be able to describe the three methods of heat transfer and provide examples of each.

Introduce the learning objective to the students.

What do you already know about heat transfer?

Slide 1: Introduction

Heat transfer is the movement of thermal energy from one object to another. It occurs in three ways: conduction, convection, and radiation.

Introduce the topic of heat transfer and briefly mention the three methods.

Slide 2: Conduction

Conduction is the transfer of heat through direct contact between particles of matter. It occurs mainly in solids.

Explain the concept of conduction and provide an example for better understanding.

Slide 3: Convection

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs in liquids and gases.

Explain the concept of convection and provide an example for better understanding.

Slide 4: Radiation

Radiation is the transfer of heat through electromagnetic waves. It can occur in empty space or through transparent mediums.

Explain the concept of radiation and provide an example for better understanding.

Slide 5: Interactive Element

Let's test your understanding! Drag and drop the examples of heat transfer into the correct category: conduction, convection, or radiation.

Engage students with an interactive activity to reinforce their understanding of the three methods of heat transfer.

Slide 6: Examples of Conduction

Examples of conduction include touching a hot stove, heating a metal spoon in hot soup, or walking barefoot on a hot sand beach.

Provide specific examples of conduction to solidify students' comprehension.

Slide 8: Examples of Radiation

Examples of radiation include feeling the warmth of the sun, using a microwave oven, or heat from a fire.

Provide specific examples of radiation to solidify students' comprehension.

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.
