Ucar: Ozone Attack
In this activity, students observe how rubber bands deteriorate, developing cracks or pits, in locations with different ozone levels.
University Corporation for Atmospheric Research
Ucar: Ozone in Our Neighborhood
Students will experiment to understand variations in the amount of ground-level ozone between different places in their neighborhood, town, or city.

Ucar: Modeling Smog
For this activity, students create molecule models using marshmallows to understand and explain how smog forms.

Ucar: Modeling a Weather Front
In this demonstration, students observe how temperature changes can create a weather front, in particular how the mixing of warm and cold air can produce thunderstorms.
University Corporation for Atmospheric Research
Ucar: Make a Tornado
Students explore factors that influence why certain areas in the United States have more tornadoes than others and observe a model to visualize what is happening during a tornado.
University Corporation for Atmospheric Research
Ucar: Glaciers Then and Now
Students compare photographs of glaciers to observe how Alaskan glaciers have changed over the last century.
University Corporation for Atmospheric Research
Ucar: Get the Picture Severe Weather
Students review graphs and charts of severe weather data then answer "True and False" questions about the content conveyed.

Ucar: Clouds in the Air: Why Are They There?
An experiment that demonstrates why there are clouds in the sky. Start with air, invisible water vapor, particles we call condensation nuclei, and air pressure...the cloud comes later!

Ucar: Modeling Wind Dynamics and Forests
In this activity, learners will develop a model of a forest using plastic bottles and then observe and analyze changes in winds related to differences in forest density.
University Corporation for Atmospheric Research
Ucar: Satellite Storm Search
Students investigate a physical model to explore how satellite data impacts weather monitoring and forecasting.
University Corporation for Atmospheric Research
Ucar: Modeling Tree Transpiration
In this activity, students will observe and measure the water given off through transpiration by a plant in a small terrarium.
University Corporation for Atmospheric Research
Ucar: Balloon Inside a Bottle
Air takes up space. It's only when air in the bottle escapes that more air is easily added!
University Corporation for Atmospheric Research
Ucar: Raise the Roof on Urban Heat
Students use a simple model to explore how roof colors can impact the temperature of an urban area.
University Corporation for Atmospheric Research
Ucar: Flood Chances
Students test the hypothesis that a 100-year flood happens once every hundred years, learning how the probability of a flood does not mean that floods happen at regular intervals.
University Corporation for Atmospheric Research
Ucar: Cloud Viewer
Use the Cloud Viewer to explore the clouds and sky outside.
University Corporation for Atmospheric Research
Ucar: The Water Cycle and Climate Change
Water moves from place to place through the water cycle, which is changing as climate changes. Learn how the water cycle is changing as global temperatures rise.
University Corporation for Atmospheric Research
Ucar: Create a Portable Cloud
In this hands-on activity, students experiment to discover how moisture, pressure, temperature, and condensation nuclei play a role in cloud formation.
University Corporation for Atmospheric Research
Ucar: Wind
Wind is air moving from a place that has higher pressure to one that has lower pressure. Sometimes wind is just a light breeze and other times it is strong enough to blow the roofs off buildings.
University Corporation for Atmospheric Research
Ucar: Visualizing Weather and Climate
With visualizations, we can see the entire planet from all angles at once. We can see the invisible - such as water vapor in the atmosphere and the way air flows around the world.
University Corporation for Atmospheric Research
Ucar: Weather Glossary
A glossary of common weather related words.
University Corporation for Atmospheric Research
Ucar: Change in the Atmosphere With Altitude
How does the atmosphere change as you go up high in the sky?
University Corporation for Atmospheric Research
Ucar: Humidity
The amount of water vapor in the air is called humidity.

Ucar: A Global Look at Moving Air: Atmospheric Circulation
Even with disruptions like weather fronts and storms, there is a consistent pattern to how air moves around our planet's atmosphere. This pattern, called atmospheric circulation, is caused because the Sun heats the Earth more at the...
