Q2 - pg. 13
• Daily Goal: We will be able to compare and
contrast convection and conduction.
• Homework: Gist
Science Starter:
1. Explain how Kongming Lanterns work.
2. Do you think that all heat is transferred
Conduction
***WRITE THIS DOWN***
• Conduction is the transfer of
energy from one molecule to
another.
• This transfer occurs when
molecules hit against each other
• Conduction takes place in solids,
liquids, and gases
Let’s learn the sign for
conduction!
Conduction
**WRITE THIS DOWN**
Conduction is
heat energy
transferred
through
direct contact
Examples:
Pan on stove
Conduction
• The fast particles (the hot ones) will transfer
some of their kinetic energy to the slow particles
(the cold ones). This will make the slow particles
move faster (and therefore have more heat).
• This happens most often in solids, because in
solids the particles are packed closely together.
Examples of Convection
• What are some examples conduction that you
can you think of?
• Make a list of examples in your notebook.
Write down at least 4.
• We will make a list of your ideas. Add to the
list in your notebook if someone mentions an
example that you don’t have.
In your notebook, create a chart that
looks like this:
Conduction
Convection
In your notebook, categorize each of
the following examples as either
conduction or convection:
• The heat you feel from a fireplace
Frying a pancake
A Warm Breeze
Your hands being heated by hand
warmers
Touching a hot handle of a pan
In your table groups, you will:
• Create a poster-sized Venn diagram comparing
and contrasting convection and conduction.
• Each of you will have a team role.
– At least 3 comparisons in each section (9 total)
– At least 3 examples of convection and 3 examples
of conduction
– Illustrations of each example

by waves.

• When we feel heat around these
items, however, we are feeling

molecules)
• Radiation is the transfer of energy by
electromagnetic waves.
does NOT require any matter. (It can happen
in empty space!)
• The best (and most common) examples of
radiation are from the sun and from heat
lamps.
• Draw one of those on your foldable. Make
sure to label the direction of heat transfer
(from hot to cold).
Heat transfer
• Can we have 3 methods of heat transfer at
once? YES!
Definition:
Transfer of heat through
space in the form of
electromagnetic waves
Example:
Beachgoer gets sunburned
• The heat you feel from a
fireplace
• This type of heat transfer
causes techtonic plates to
move
• boiling water
• Heat you feel from a hot
stove
• Frying a pancake
• fast particles colliding with
slower particles

air travels this way
transfer through solids
transfer through space
moves as a wave
moves as a current
sun rays reaching earth
occurs with fluids
a coil on an electric stove
this type of transfer is
affected by color
