1. The Heat is On !!
A Fourth Grade Lesson
Understanding How
Thermal Energy is
Transferred

2. Michigan 4th Grade Science Grade Level
Content Expectations
• S.RS.04.11 Demonstrate scientific concepts through various
illustrations, performances, models, exhibits, and activities.
• P.EN.E.1 Forms of Energy- Heat, electricity, light, and sound
are forms of energy.
• P.EN.04.12 Identify heat and electricity as forms of energy.
• P.EN.04.42 Describe heat as the energy produced when
substances burn, certain kinds of materials rub against each
other, and when electricity flows through wire.
• P.EN.04.43 Describe how heat is produced through electricity,
rubbing, and burning.
• P.CM.04.11 Explain how matter can change from one state
(liquid, solid, gas) to another by heating and cooling.

3. Michigan Educational Technology Standards
Grades 3-5
TECHNOLOGY COMMUNICATIONS TOOLS
By the end of Grade 5 each student will:
1. use basic telecommunication tools (e.g., e-mail,
WebQuests, IM, blogs, chat rooms, web
conferencing) for collaborative projects with
other students
2. use a variety of media and formats to create and
edit products (e.g., presentations, newsletters,
brochures, web pages) to communicate
information and ideas to various audiences

4. Let’s Jump Start Your Thinking
(What do we KNOW about heat?)
• When we are outside, we can feel the heat
from the sun
• If we touch a hot pan with our bare hand
we might get burned
• When we sit by a campfire we get warm
even though we are not touching the fire
• Other ideas……..

5. Lesson Objectives
(WHAT do we want to know about heat?)
• Students will understand that adding or
removing heat from a substance can change its
state of matter.
• Students will identify conduction as a physical
property of matter.
• Students will recognize that thermal energy
can be transferred from one object to another
through conduction, convection, and
radiation.
• Other things we want to learn about heat……

6. What is Heat?
• The transfer of thermal energy from one
piece of matter to another (Frank, 2000).
• It is transferred naturally from hot matter
to cold matter.
– If you hold an icicle in your hand long enough it
will melt
– When you walk in hot sand, your feet get warm

7. How is Heat Transferred?
• Heat is transferred in three ways:
–Conduction
–Convection
–Radiation

8. What is Conduction?
• The transfer of thermal energy by particles
of matter bumping into each other (Frank,
2000).
– Hot burner to metal pot
– Hot sand to your feet
– Hot cocoa to your cup
– Warm hand to ice cube
Other ideas…..
Conduction Animation

9. Conductors and Insulators
• Conductors – materials that easily conduct
thermal energy (Frank, 2000)
– Metals
– Copper Wire
• Insulators-materials that don’t conduct
thermal energy well (Frank, 2000)
– Glass
– Wood
Conductors and Insulators Game

10. What is Convection?
• Convection is the transfer of energy by
particles of a liquid or gas moving from one
place to another (Frank, 2000).
– Hot air is less dense and is forced up by cooler
air
– As the hot air cools, its density increases and it
sinks
– The process then repeats
Convection Animation

11. Examples of Convection
• The air being heated from a fireplace
• The air being heated from a furnace
• Boiling water
• The air being heated in a hot-air balloon
Other ideas……

12. What is Radiation?
• The bundles of energy that move through
matter and empty space are radiation
(Frank, 2000).
• Bundles of energy that transfer heat are
called infrared radiation (Frank, 2000).
Radiation Animation

13. Examples of Heat Transfer by Infrared
Radiation
• The sun heating our skin
• Warming your hands on the sides of a
campfire
• Heating Food with a Microwave Oven
Other ideas……

14. You’re the Expert Now
(What did we LEARN about heat?)
• Heat is the transfer of thermal energy from
one piece of matter to another (Frank, 2000).
• Thermal energy naturally moves from warm
matter to cool matter (Frank, 2000).
• Conduction and convection need moving
particles of matter in order to transfer energy
(Frank, 2000).
• Infrared Radiation transfers thermal energy
through matter and empty space

15. Quick Quiz
Conduction, Convection,
and Infrared Radiation
Name three ways that
thermal energy is
transferred.

transferred in liquids and
gases through which type
of heat transfer?

hot through which type of
heat transfer?
Convection
Radiation

16. Question of the Week
(Wiki Work)
You must go on the class Wiki and post a response to the weekly
question.
