Heat and light - lesson 3

Heat and Light Lesson 3

You are going to learn how thermal energy travels through objects. It can be: 1. Conduction occurs when two objects are in contact. 2. Convection occurs when thermal energy travels through a gas or liquid 3. Radiation is when energy transferred from the Sun to the Earth.

Use your Natural Book, read on page 22, after that, copy the three definitions and draw a picture to show an example ot each concept. For example:

Now you are going to learn how some material can be: Conductor or insulator. Read page 23 (Natural Book) A thermal conductor is a material that transfers thermal energy. For example: a pan A thermal insulator is a material that doesn't transfer thermal energy. For example: wood
