The National Snow & Ice Data Center (NSIDC) is a great place to learn more about glaciers. Explore the life cycle of a glacier, review the components and types of glaciers, take a look at current glacier data, and browse through the extensive image gallery. You may want to share this resource with your students.
Crash Course: Glaciers is a fast-paced video with helpful animations that cover the basics of glaciers, the processes of glaciation, and the benefits of glaciers to Earth's systems.
Because glaciers are so sensitive to environmental changes, the Environmental Protection Agency (EPA) has designated glaciers as a key climate indicator related to the effects of climate change. Take a look at the EPA's data regarding changes in glaciers and ice sheets.
PBS LearningMedia's glacier resources are designed to be used by educators in the classroom and include video, interactives, discussion questions, lesson plan, or background reading.
Glacier Power is a terrific middle-school curriculum produced by the Alaska Satellite Facility. There are ten lessons, each with vocabulary, worksheets, discussion questions and hands-on projects. An additional lesson answers the question Why Do Scientists Study Glaciers?
Teacher Planet offers a collection of glacier lesson plans, printables, worksheets and experiments. Worksheets are also available at 3D Geography.
At NeoK12, you'll find classroom glacier resources including lesson plans, videos and slide presentations.
Geography All The Way has a series of glacier lesson plans with helpful diagrams and photos illustrating alpine glacial processes and erosional and depositional landforms. For older students, the lesson plan Where Have All The Glaciers Gone? includes links for further exploration.
An excellent source for photos and images of glaciers of all types, as well as glacial landforms and location maps, is the USGS's comprehensive Glossary of Glacial Terminology. Each term is accompanied by photos. Another good source is the Glacier Photo Gallery at the National Snow and Ice Data Center.
If your students are interested in the work of glaciologists, you may want to direct them to profiles of glacier scientists at National Geographic and NASA Kids, or to the work of young students currently helping with glacier research.
For older students, the University of Colorado's glacier simulation explores the impact of environmental variables on whether glaciers advance, retreat, or stay at equilibrium. Another good resource for secondary students, Antarctic Glaciers, contains photos and facts on glacial mass balance, ice cores, landforms, ice streams and more.
One of the most effective ways for students to see how glaciers have changed in the last 50-100 years is by observing side-by-side image pairs. You may want to show your class the repeat photos from these sources:
