Benchmark Descriptions
• SC.4.P.11.1 – Recognize that heat flows from a hot
object to a cold object and that heat flow may cause
materials to change temperature.
• SC.4.P.11.2 – Identify common materials that
conduct heat well or poorly.
Energy is all around us!
• You can hear energy as sound when
someone talks.
• You can see energy as light from the sun
or a lamp.
• You can feel it as heat warms things up.
What is the Transfer of Energy?
Energy can move from one object to another.

What are some transfers of energy
taking place in our classroom, in our
school or at home?
What is Thermal Energy?
• Thermal energy is the total of all the kinetic
and potential energy of the atoms in an object.
• When any form of matter gets warmer, the
kinetic energy of its atoms increases.
• The object’s particles move faster, so its thermal energy
increases.
• A change in thermal energy can lead to a change in phase or
state of matter.
• Temperature is a measure of thermal energy.
ESSENTIAL CONTENT
Heat (Thermal) Energy
• Energy of moving particles
• Energy moves from a warmer are/object to a
cooler area/object.
• Flow of heat energy may cause objects to
change temperature.
• Thermometers are used to measure the
temperature of how hot or cold something is.

How Does Heat Move?
• Thermal energy flows from warmer
substances to cooler substances.
• Heat can be transferred from one object to
another.
