*Fill in the blanks for these Key Elements
Unit I Can Statements
1. _Light__ energy from the sun is mostly transmitted through
I Can develop a model of the water cycle.
I Can describe how water enters and leaves the atmosphere.
I Can describe the difference between temperature and heat.
I Can describe the three ways that heat moves(transfers).
I Can model radiation, conduction, and convection.
I Can conduct an investigation focusing on recording and analyzing
data to determine if thermal energy can be transferred from
one object to another.
I Can conduct an investigation to explain what happens if hot air
and cold air are next to each other.
I Can create a model using evidence from data to describe what
happens to air when it is heated and cooled.
I Can make observations to determine how storm clouds are
different from other clouds.
I Can analyze and interpret data to identify patterns from an
actual storm and can construct an explanation to tell why the
storm happened.
I Can construct and use a model to describe how the Earth’s air is
heated by conduction.
**You should be able to explain what each of these I Can statements
is referring to by giving examples.
**Things to study:
Vocabulary definitions
All bellringers
the air before reaching the __ground__, and the ground
___absorbs__ some of the light energy that reaches it.
2. Molecules transfer __thermal__ energy from one end of an
of an object to another and to other objects by _collisions__
between molecules that transfer the kinetic energy of one
molecule to another (__conduction_).
3. The _air__ at the Earth’s surface is primarily heated by the
transfer of __thermal_ energy from the ground below it.
4. _Less__ dense air rises when surrounded by more dense things.
The __more__ dense air moves in to take its place. The
movement of air masses is called _convection__.
5. Air _pressure_ at a location is related to the total weight
of the air above that location. Low-density air columns have _less_
pressure and high-density columns have _more_ pressure.
6. A __front_ is the boundary between large air masses.
7. Air masses move when _high_ -pressure air pushes into the
space of __lower_-pressure air. At the surface, higher
differences in pressure over smaller distances result in stronger
_winds__.

Read over any notes & Key Elements from water cycle, heat
transfer and weather information!
8. Air masses move when _more_ dense air slides underneath
less dense air, causing the __less_ dense air to be lifted
upward. This _less_ dense air is unstable as it is forced
upward. It transfers __energy_ to the surrounding air and
cools as it rises.
9. Movement of air masses causes _changes_ in weather in
predictable ways.
10. Complete the table.

11. What is the difference between a weather event and weather
condition?
-conditions are things that act together to create an event such
as temperature, air pressure, wind, humidity, precipitation, etc
-events are the culmination of conditions –storms, tornadoes, etc
12. Heat always moves in what direction?
-heat moves from warmer areas/objects to cooler areas/objects
13. Why is air considered to be matter?
-it is made of molecules, has mass and volume
14. What are the processes that water goes through the water
cycle to change its state of matter?
-evaporation -liquid to gas
-transpiration – liquid to gas
-condensation –gas to liquid
-precipitation -liquid to liquid/solid
Earth and its atmosphere.
*Be sure to be able to show/label -radiation, conduction,
convection, temperatures, air pressure, heat sources,
air molecule arrangements, arrows for movement
-class models
