Four activities that make connections between the science of clouds, art and literacy: Available at Windows to the Universe (www.windows2universe.org), a National Earth Science Teachers Association educational project. Students exploreClassroom Activitythe conditions needed for clouds to form.Cloud in a Bottlethe different types of clouds.Cloud Viewerclouds in the sky and write poetry about nature, including clouds and weather.Our Poetic Planethow Western artists have represented clouds in landscape paintings.Clouds in ArtCloud in a BottleIn this activity, students learn how clouds form by making a cloud in a bottle. There must be three main ingredients present in order for clouds to form: Moisture there must be sufficient water vapor in the air to build a cloud Cooling air the air temperature must decrease enough for water vapor to condense Condensation nuclei tiny particles such as dust provide surfaces on which water molecules can gather and condense into water dropletsCloud in a BottleUse a Fizz-keeper and matches to create a cloud Record the initial temperature of the bottle.Pump the Fizz Keeper 20 times. Record the temperature. Pump the Fizz keeper 20 more times. Record the temperature. Repeat this two more times so you have recorded the temperature after 60 and 80 pumps.Unscrew the Fizz Keeper and record the temperature of the bottle.Now pour a small amount of water into the bottle. Light a match and drop it into the bottle. Quickly screw the Fizz Keeper on the bottle and repeat steps 1-3 above.What happened after you unscrewed the Fizz Keeper the final time?* If using air freshener, do not use a match! Keep the matches separate from air freshener when putting out supplies.Discussion: How Do Clouds Form?There are four main ways clouds form:Surface HeatingMountains and TerrainAir masses being forced to riseWeather fronts (cold or warm)

All of these processes involve the cooling of air and the presence of condensation nuclei. Eventually, enough water vapor will condense upon condensation nuclei to form a cloud. The water droplets may fall down to Earth in the form of rain or snow. The sun heats the Earth, which heats the airThe warm air is lighter and less dense and begins to riseWhen it rises, it expands because of the lower pressures that exist at higher levels in the atmosphereWhen air expands because of a drop in pressure it also coolsThe cooling air cant hold all the water vapor, so it begins to condense into water dropletsEventually, enough moisture condenses out of the air parcel to form a cloudCumulonumbus, cumulus, and stratocumulus clouds form this way

Cloud Formation Due to Surface Heating

Some clouds form when air encounters a mountain range or other types of terrainThe air rises over the mountain and cools, and forms a cloudCumulonimbus and cumulus clouds form this way

Cloud Formation Due to Mountains

Some clouds form when air at the surface is forced to rise. This happens from three different processesIn a low pressure system, wind moves into the center from all directions (from high to low pressure). When it meets at the center there is no where to go but up.Air is forced to rise when it is traveling over land that slopes upward. The air cools as it rises, and eventually clouds will form.Weather fronts produce clouds by causing air to rise when the lighter warm air flows over the heavier cool airAll cloud types are formed by these processes, especially altocumulus, altostratus, cirrocumulus, stratocumulus, and stratus

Clouds Formed by Air Being Forced to Rise

Weather fronts occur when two large masses of air collide at the Earths surface these can cause clouds to formWarm fronts produce clouds when warm air replaces cold air by sliding over itWarm fronts produce many types of clouds: altocumulus, altostratus, cirrocumulus, cirrostratus, cirrus, cumulonimbus, nimbostratus, stratocumulus, and stratusCold fronts occur when heavy cold air displaces lighter warm air, pushing it upwardCold fronts produce cumulus, cumulonimbus, nimbostratus, stratocumulus, and stratus clouds

Cloud Formation Due to Weather Fronts

Cloud TypesClouds can be divided into groups mainly based on the height of the clouds base above the Earths surface

Cloud #1This is an image of cirrus clouds. These clouds are thin, wispy, and feathery.

Cloud #2This is an image of cumulus clouds. They are puffy white or light gray clouds that look like floating cotton balls, have sharp outlines, and have a flat base.

Cloud #3This is an image of stratocumulus clouds. These clouds are low, lumpy, and gray.

Cloud #4This is an image of altocumulus clouds. These clouds can be in groups or rows.

Cloud #5This is an image of cumulonimbus clouds. These clouds are large, have an anvil-shaped top, and are associated with thunderstorms.

Clouds in ArtClouds in Art Interactive

Students explore how Western artists have represented clouds in landscape paintings while honing their cloud identification skills and making their own cloud paintings. Our Poetic PlanetStudents make observations of clouds and weather and write poetry about nature about what they observed.

Our Poetic PlanetPoetry about clouds, weather, and other aspects of the Earth can be very descriptive. Poetry is a form of expression that allows students to write about their observations about the natural world. Share published poems with students Discuss different types of poetry Create a word wall with your class to give them descriptive words to use in their poems (good strategy for learning readers and English language learners)Science and Literacy for English Language Learners Science process skills are almost the same as language learning skills. Science provides great content that serves as a back bone for language acquisitionScience Process Skills Observing Predicting Communicating Classifying AnalyzingLanguage Learning Skills Seeking information Comparing Ordering Synthesizing EvaluatingExamples of Poetry about Weather and CloudsFOG
