• Actually, rather than thinking of black as
absorbers of heat, darker colors are better
absorbers of light and thereby become
better radiators of heat.

• RED SLIDE: These are notes that are very
important and should be recorded in your
science journal.

-Nice neat notes that are legible and use indentations
when appropriate.
-Example of indent.
-Skip a line between topics
-Don’t skip pages
-Make visuals clear and well drawn.

• RED SLIDE: These are notes that are very
important and should be recorded in your
science journal.
• BLACK SLIDE: Pay attention, follow
directions, complete projects as described
and answer required questions neatly.

 New Area of Focus: Light and Temperature.

• What’s light?
– Sounds like an easy question but is it?

• Answer! Light
– The form of radiant energy that stimulates the
organs of sight, having for normal human
vision wavelengths ranging from about 3900 to
7700 ångstroms and traveling at a speed of
about 186,300 miles per second.
• One ångstrom = 10-8 cm (0.00000001 cm).

 Light: An energy wave.

• What’s the point here?

• Answer! The black paint absorbs light instead
of reflecting it toward the eye, allowing an
athlete to see clearer in sunny conditions.

 Black absorbs all colors of the spectrum
while white reflects.

• Activity! Temperature change and Albedo.
– Fold a piece of white construction paper and
black construction paper in half.
– Staple sides to make a pocket.
– Place thermometer bulb in each pocket equally.
– Safely place under light (60 Watt or greater) so
both sides receive equal light.

– Q’s: Which color will absorb more light and
thus have a higher temperature?
• Use data in your response
– Q’s: Which color will reflect more light and
thus have a cooler temperature.
• Use data in your response.

– Q’s: Which color will absorb more light and
thus have a higher temperature?
• Use data in your response
– The black colored paper absorbed more light
and thus had a higher temperature. The final
temperature of the thermometer in the black
paper was ____ greater than the white.

– Q’s: Which color will reflect more light and
thus have a cooler temperature.
– The white colored paper reflected more light
and thus had a lower temperature. The final
temperature of the thermometer in the white
paper was ____ less than the black.

• Will the light be reflected or absorbed in
the picture below?

• Cloud cover reflects light into space.

• What are these?

• Volcanoes can control global climate /
light.

• Snow and ice caps.
– How would loss of ice caps dramatically warm
the planet?

• The Oceans then warm b/c light is absorbed
instead of reflected back into space. Ice Melts

• Wear sunscreen on the slopes

• Wear sunscreen and eye protection on the
water as light is reflected here as well.

 Albedo: The reflectiveness of a surface.

 Dark colored materials heat up quicker
than light colored materials. So air above
dark colored surfaces heats up quicker.

 Temperature: A measure of the average
kinetic energy (motion) of individual
molecules in matter.

High Temperature
Fast molecular motion
Low Temperature
Slow molecular motion

• The kinetic theory of matter:
• Atoms and molecules (particles) are in
constant motion.
– The higher the temperature - the higher the
speed.
– Increased heat energy make atoms and
molecules move faster.

• Which of the pictures below represents hot
and cold on a molecular level?
A B

• Answer: Molecules move faster when hot,
and slower when cold.
Hot Cold
A B

• This is really cold.
– Absolute zero has no molecular motion.
– Never been reached.

 0 Degrees Celsius is the freezing point of
water.

 0 Degrees Celsius is the freezing point of
water.
 100 degrees Celsius is the boiling point.

• When it’s hot, the liquid inside the
thermometer will expand and rise in the
tube.

• When it’s hot, the liquid inside the
thermometer will expand and rise in the
tube.
– The opposite happens when it is cold.

• Activity! Please convert 95 degrees
Fahrenheit into degrees Celsius.
– Formula is on the next slide.

• Activity! Please convert 95 degrees
Fahrenheit into degrees Celsius.
– Formula is on the next slide.
“The Fahrenheit
Scale makes me
angry!”

• To convert 95 degrees Fahrenheit
temperatures into Celsius:
– Begin by subtracting 32 from the Fahrenheit
number.
– Divide the answer by 9.
– Then multiply that answer by 5.

95 - 32 = 63.

95 - 32 = 63.
Then, 63 divided by 9 = 7

95 - 32 = 63.
Then, 63 divided by 9 = 7
Finally, 7 times 5 is 35 degrees Celsius.
