An introduction to the Ice Balloons activity, in which learners explore globes of frozen water and learn how to ask and then answer 'investigable' questions.

00:07:39
A detailed demonstration of how to do the Ice Balloons activity, including a discussion of materials needed and strategies for getting learners to ask and then investigate questions about what they are seeing.

00:01:03
The science and pedagogy behind this activity, including a discussion of concepts such as density, temperature, thermal conductivity, center of mass, freezing point depression, heat capacity, and the characteristics of the states of water, water vapor, and ice. Also describes strategies for observing, asking questions, and then choosing a question to investigate further.

Dr. Bart Kempenaers, a behavioral ecologist from the Max Planck Institiute of Ornithology in Seewiesen, Germany, and his team fashion fake Sandpiper eggs, swap them for the real ones in the nest and incubate them in their lab at BASC’s (Barrow Arctic Science Consortium) new research facility. Once the hatchlings emerge, they take samples from them to determine factors such as paternity. The chicks are then returned to the nest, without the mother batting a feather.

What does a ringed seal’s breathing hole look like and how do you find one on a vast sheet of sea ice? Dr. Brendan Kelly uses the canine skills of Cooper, a Black Labrador he trained to chase the scent of ringed seals and point to their holes. Passionate about wildlife and climate change, Melanie Duchin has loaned her dog to work with Brendan for the past 5 years.

Alaska's coastal range is covered in literally thousands of thaw lakes. Ken Hinkel, Yongwei Sheng and John Lenters are embarking on a project to reveal the subtle energy dynamics that take place within these lake systems.

Dr. Jewel Bennett, an endangered species biologist with the US Fish and Wildlife Service's Fairbanks field office, is in Barrow leading a survey team tracking the endangered Steller's and Spectacled Eiders' populations.

Watch Dr. Brendan Kelly, Micaela Ponce, Kevin Bakker and Dan Carlson as they measure and tag a female ringed seal on the frozen Chukchi Sea. Follow them as they return the seal by snowmobile to her breathing hole in the Elson Lagoon - and get a little seal slap in the process.
