Thermal energy can be transferred between objects in three ways: conduction, convection, and radiation. Conduction involves the transfer of thermal energy between objects in direct contact with each other. Convection is the transfer of thermal energy through the movement of liquids or gases. Radiation involves the transfer of thermal energy through electromagnetic waves that can pass through empty space between objects.

2. THERMAL ENERGY travels between
objects that have different
temperature

from WARMER to COLDER
3 WAYS THERMAL ENERGY CAN
TRAVEL

3. CONDUCTION
Transfer of thermal
energy between two
objects that touch each
other

4. How does CONDUCTION
happen in this picture?

5. How does CONDUCTION
happen in this picture?

6. CONDUCTOR
an object that lets
thermal energy pass
through it easily
METALS are the best
kind of conductors

7. INSULATOR
an object that DOES
NOT let thermal
energy go through

8. CONVECTION
transfer of thermal
energy by movement
of a gas or liquid.

10. How does
CONVECTION happen
in a hot air ballon?

11. RADIATION
transfer of thermal
energy by waves.
transfer of thermal
energy through
empty space.

12. How does RADIATION happen in this picture?

13. How does RADIATION happen in this picture?

14. Dark objects absorb
more radiation
Light objects absorb
less radiation
