Slide 2
Get ready! Take out your lab worksheet from yesterday.
(relative humidity lab)
Slide 3
Yesterday Address yesterday mistake: dew point chart, instead
of relative humidity chart
Slide 4
Slide 5
Clouds Condensation and Precipitation
Slide 6
Weather and Climate Unit MYP Unit Question: What should I wear
today? Area of Interaction: Environment Learner Profile:
Communicator
Slide 7
Weather and Climate Unit Standard: Understand how the
distribution of land and oceans affect climate and weather Learning
Target: Today I am learning about condensation and dew point
because they are necessary for cloud formation.
Slide 8
A Quick Lab 1.Room-temperature water in a plastic cup water
level near the top. 2.Observe the outside of the container. Record.
3.Lets add 2-3 ice cubes. 4.Are there any changes on the outside of
the plastic cup? 5.What is the liquid on the container? Where did
it come from?
Slide 9
Condensation The water came from the surrounding air, and
droplets formed as a result of condensation.
Slide 10
Water Cycle - Condensation

Slide 11
Condensation Condensation is a process by which gas, such as
water vapor becomes a liquid. The air must be saturated = relative
humidity of 100% Condensation occurs when saturated air cools.

Slide 13
Dew Point Dew point is the temperature at which a gas condenses
into a liquid. Air is saturated at its dew point. It must have a
surface to condense on.

Slide 15
What is a cloud? It is a collection of millions of tiny water
droplets or ice crystals suspended in the air. It forms when the
air is cooled and condensation occurs.
Slide 16
Clouds Evaporation Water converts to vapor as it evaporates and
rises up into the atmosphere.
Slide 17
Clouds Condensation Water vapor will condense on tiny particles
in the air to form water droplets known as condensation.
Slide 18
Clouds Cloud formation: A cloud is essentially a huge mass of
water droplets or ice crystals suspended in the atmosphere.
Slide 19
Clouds Clouds are classified by form and altitude.
Slide 20

No two clouds are exactly alike, and they are always changing their
shape. The reason we have different types of clouds is that clouds
formation takes place at different heights and temperatures.
Slide 21
Cirrus Cumulus Stratus
Slide 22
Cumulus Cumulus means heap, like a pile = cumulus puffy
Indicate fair weather
Slide 23
Cumulonimbus Tall, dark and very puffy and large (billowing)
Thunderclouds! May produce rain, hail, lightning, thunder &
tornadoes Nibo/ nimbus = likely to produce precipitation
Slide 24
Stratus Stratus = layers spread out, like a blanket or sheet
Lowest of the clouds
Slide 25
Nimbostratus Dark stratus clouds that usually produce light to
heavy, continuous rain.
Slide 26
Are fogs and clouds the same? There is no basic difference
between a fog and a cloud. A fog is a stratus cloud that formed
near the ground. They are caused by a cold current of air from
above striking down upon the warmer surface of the land or
water.
Slide 27
Cirrus Mainly composed of ice crystals Thin and wispy, feather
like Fair now, but can get thicker = indicate a change in weather
Cirrus = hair
Slide 28
Precipitation
Slide 29
Refers to water in any form that falls from the atmosphere/
clouds. Rain Sleet Snow Hail
