Ask a Question

Synopsis
  • This resource displays 12 interactive image pairs of glaciers from Glacier National Park in Montana. 
  • The image on the left of each pair is from some point in the early 20th century and the image on the right is more recent. 
  • Viewers are able to move a slider between the images to see how the glaciers have receded over time. 
Teaching Tips

Positives

  • The slider feature on the photos will be engaging for students.
  • These photo pairs do a great job of illustrating the effect of climate change on glaciers.
  • The photos can be used in a wide variety of subjects and grade levels.

Additional Prerequisites

  • This site includes 12 photo pairs, but there are over 60 in the collection. Click the Repeat Photography Project link at the top of the page to read more and view the entire collection. All images are available for download.

Differentiation

  • These photos would act as a great phenomena to start a Next Generation Science Standards lesson or unit on the effects of global warming or the cause of rising sea levels.
  • The resource Images of Change by NASA has similar slidable comparison pictures that illustrate climate change. It includes glaciers as well as images from floods, hurricanes, landslides, and droughts.
  • Other resources related to glaciers include the lesson and activity Glaciers Interactive Simulation, the experiment What's Happening at the Poles?, and NASA's webpage on Ice Sheets.
Scientist Notes
This resource contains photos that describe the physical process of glaciers and compares the level of retreat from each intervals until 2021. The report is evidence-based, and it is recommended for teaching.
