This document discusses thermal energy and the different types of heat transfer. It explains that thermal energy is a measure of molecular kinetic energy and can be measured using thermometers in degrees Fahrenheit, Celsius, or Kelvin. The three main types of heat transfer are conduction, convection, and radiation. Conductors easily transfer heat through direct contact while insulators do not, and convection involves heat transfer through molecular movement caused by temperature and density differences, as seen in wind and boiling water. Radiation transfers heat through space without direct contact.

1. Thermal Energy
• 6th grade science

2. • Measure of kinetic
energy of molecules
• Thermometer
• Fahrenheit
• Celsius
• Kelvin

3. • Measurment related to
the quantity of
molecules.

4. • Thermal energy always moves from warmer
to cooler objects.
• Heat is the result of molecules vibrating
quickly.
• Heat is moving energy.

5. • The transfer of heat by
direct contact between
objects or particles.

6. • Heat transferred
through space.
• EXAMPLE: The
sun’s rays causing a
sunburn.

7. • Heat transferred by the
movement of
molecules within a
substance.
• Movement occurs
from warmer areas to
cooler areas.

8. • The movement of a substance that is caused
by differences in temperature and density.
• EXAMPLES: wind
boiling water
• NATURE WANTS
EVERYTHING TO BALANCE ! !

9. • Conductors are
materials that transfer
heat easily.
• Examples: metals like
copper and gold

10. • An insulator is a
material that does not
transfer heat easily.
• Examples:
• liquids and gases
• A jacket
