Lesson 10: Heat Transfer

Heat Transfer

Introduction

Hello scientists! Did you know that heat transfers, or moves?  In fact, heat moves from warmer areas to cooler areas through the transfer of thermal energy.

Visual

Take a look at these images, and think about the questions below.

 

• If you leave a cup of hot chocolate on a counter for a while, what happens to the temperature of the drink?
• If you leave a cup of iced tea out, what happens to the temperature of the drink?
• Why do you think that hot things get colder when they are left out, and cold things get hotter?

Assignment

The important thing to remember with heat transfer, is the energy always flows from HOT to COLD.

For today's activity, think about the following scenarios.  Write your thinking in your science journal. 

	How would your hands feel after holding a bowl of steaming hot soup?  Would there be any heat transfer? Which direction?
	How would your hands feel after throwing snowballs? Would there be any heat transfer?  Which direction?
	How would your hands feel after touching another object the same temperature as your hand? Would there be any heat transfer?  Which direction?
