Size and scale can be difficult concepts to teach. TI staff educator Lori Lambertson talks us through one of her favorite activities, using one of her favorite dolls-Barbie.

What coin would just barely cover the full moon? You may be surprised. TI director (and recovering astrophysicist) Linda Shore explains how our brains distort the actual size of the moon.

It can be hard to make ideas about size and scale relevant to students’ lives. Children’s book author David Schwartz explains a series of neat real-world comparisons from his book that really get the concepts across.

00:05:59
Exploratorium staff physicist Thomas Humphrey reveals why size does matter, at least in physics.

In this interview from in front of the Canada Glacier in Antarctica’s Taylor Valley, Hassan Basagic from Portland State University describes the essential role of polar glaciers in supporting the bare-bones ecosystems in the Dry Valleys.

The POLENET project installed their newest high-precision GPS system on Deverall Island, Antarctica. These GPS systems tell scientists how much the ground underneath the ice sheet is moving upward. This has important implications on the movement of the West Antarctic Ice Sheet and its interplay with the rock below. Learn more about it in this audio report from correspondent Kelly Carroll.

In this audio dispatch, correspondent Jack Walter describes his first week at the team's field camp on the West Antarctic Ice Sheet. Hear about their research on lakes under the glaciers and get a slice of life as a remote polar scientist.

In this interview from Greenland, glaciologist Mark Fahnestock describes the roar of a 1000-foot iceberg dropping off the Jakobshavn Isbræ into the Ilulissat Icefjord. Includes time-lapse photography of this massive calving event.

00:01:55
What controls the speed of Greenland’s big outlet glaciers like the Jakobshavn? How do they interact with the climate system? And most importantly, what does the future hold for the glaciers of Greenland? In this video, glaciologist Mark Fahnestock discusses glacier dynamics and what he hopes to learn through his studies.

The Ice Stories crew caught up with glaciologist Mark Fahnestock on his way back home after a few weeks camping near Greenland's Jakobshavn Isbræ, the most productive and among the fastest-moving glaciers in the world. In this interview, Mark describes some of the physics of this speedy glacier and why so many scientists are interested in studying the dynamics of Jakobshavn.
