This animated module explains and illustrates how and why different types of clouds form in the atmosphere.

In this project activity, students learn about different types of clouds and determine which type of cloud is most commonly overhead in their area over a period of four weeks.

During this project, students observe convection current by performing two lab experiments. As a result of these activities, students develop an understanding of the process of convection, and apply the knowledge to processes in the atmosphere.

In this lesson, students use ImageJ to create a 3D representation of a digital elevation model, then calibrate the image from known elevations. Using a slightly altered version of the digital elevation model (DEM), students compare what the elevation of the glacier might look like 100 years from now and explore how a DEM can be used to analyze changes in elevations over time.

In this lesson, students will learn about global climate change, what causes global warming, and scientific projections about climate change in the near future.

In this activity, students observe a demonstration of the role of thermal conductivity in heat transfer, explore the properties of snow, and design and conduct an experiment to compare the thermal conductivity of four substances.

In this activity, students learn about the greenhouse effect and its possible effects on global warming and rising water levels on Earth.

This module illustrates and describes the natural and manmade processes that release carbon dioxide into the atmosphere. Students can play a simple game to determine which process releases the most carbon dioxide.

In this activity, students build an anemometer and then measure wind speed in areas of differing topography to study how natural and man-made topography affect wind speed.

Students use the Internet to collect and compare data from a regional coastal weather station to data from an inland area (along similar latitudes) to determine what effect oceans have on temperature and climate.

Students will design and conduct an experiment to test how long it takes for air to become saturated.

In this module, students learn how the layers of an ice core can reveal clues about ancient temperatures, atmosphere, and climate.

In this lesson, students learn about the carbon cycle and how carbon dioxide enters the atmosphere.

In this lesson, students investigate basic principles that relate to thermohaline circulation. Then they view a short video that connects these concepts to oceanic circulation and the potential for climate change.

In this activity, students explore insulation and heat transfer by designing and testing a soda insulator.

In this activity, students use data collected in previous lessons ("The Science of Snow" and "Lake Ice and Energy Transfer") to determine the thermal conductivity of snow and mean conductive heat flow.

In this activity, students use data collected in a previous lesson ("The Science of Snow") to determine snow temperature gradient.

Students learn the composition and layers of the atmosphere through discussion, creation of a scale model, and a written exercise.

In this lesson, students will review the hydrologic cycle and will identify its stages in their communities and will speculate on possible uses for hydrokinetic energy in their communities.

In this activity, students use their senses to explore objects before and after heating.

In this activity, students observe a discrepant event, explore thermal energy and energy transfer, and apply their knowledge of energy transfer to sea ice processes.

This animated module explains and illustrates the movement of molecules in water in each phase.

In this activity, students will learn that wind is named for the direction from which it comes. Students will practice with cardinal directions by running in the direction of the wind named by the teacher.

In this activity, students will understand the persistence method of forecasting and make a weather prediction using the persistence method.

In this lesson, students reflect upon the ways they prepare for warm and cold weather in their area by drawing and describing the clothes they wear on warm and cold days.

In this activity, students use the scientific method to conduct a lab measuring snow density and calculating snow water equivalent.

Students explore satellites - what they are, how they work, how they are used, and how to interpret satellite images of sea ice using Google Earth.
