1. Investigating
Heat and Temperature

2. LabsLabs
 Lab 1: Hot and Cold
 Lab 2: Tracking the Heat

3. Hot and Cold:Hot and Cold:
Comparing Heat and TemperatureComparing Heat and Temperature

4. Objectives:
 The student will illustrate and
explain the results of addition or
subtraction of thermal energy on
the motion of molecules
 Distinguish between heat and
thermal energy

5. Key Terms:Key Terms:
 Heat
 Temperature
 Thermal Energy

6. Heat
 The energy transferred between
two substances which are at
different temperatures

7. Temperature
 The
measurement of
the average
kinetic energy of
the molecules of
a substance

Kelvin

Celsius

8. Thermal Energy
 The term used
to describe the
total energy of
the particles
that make up a
substance in an
energy
exchange

9. Essential Learnings
 Hot and cold are relative terms,
defined by the individual much like
large and small, and they are not
scientific terms.

10. Essential Learnings
 Molecules of all substances,
regardless of their state of matter
(solid, liquid or gas) are in constant
motion and have Kinetic Energy
 Temperature is directly related to
the rate of motion of molecules
 It is the measure of average kinetic energy

11. Essential Learnings
 Thermal energy is defined as the
energy of a substance, both its
average kinetic energy (temperature)
and the kind of molecules in the
substance

12. Essential Learnings
 Heat is energy that is transmitted
between substances based on
differences in the kinetic energy of
their molecules
 Heat moves from “hot” to “cold”

14. Objectives:
 The student will investigate and
understand processes that transfer
energy between substances
 Understand that thermal energy
is the total energy of the particles
that make up a substance

15. Objectives:
 The student will investigate and
understand processes that transfer
energy between substances
 Understand that heat is the
transfer of energy from one
object of higher temperature to
one object of a lower temperature

16. Objectives:
 The student will investigate and
understand processes that transfer
energy between substances
 Understand that temperature is a
measure of the average kinetic
energy of the particles in a
substance

17. Key Terms:Key Terms:
 Thermal Equilibrium
 Conduction

18. Thermal Equilibrium
 Term used to describe the
equalization of temperatures between
a substance and its surroundings.

19. Conduction
 The transfer of thermal energy
through direct contact

20. Essential Learnings
 When two materials are in contact,
energy is transferred from the one
with the higher temperature to the
one with the lower temperature by
conduction due to the kinetic
energy of the particles in contact

21. Essential Learnings
 The vibrating molecules from the
object with the higher temperature
come in contact with the molecules of
object with the lower temperature.
 Energy is transferred causing the
cooler object to “warm up” as
molecule vibration increases

22. Essential Learnings
 Materials at Thermal Equilibrium
have the same temperature; objects
come to thermal equilibrium with their
surroundings
 Room temperature objects don’t feel like
room temperature because of human body
temperature, insulators and conductors.

23. Essential Learnings
 Hypothermia is a medical condition
when a human’s body temperature
drops from its normal body
temperature to one much lower
because of the lost heat to the
surrounding environment
