Watch this video to learn about how researchers identify narwhals and estimate wildlife populations. This video includes underwater footage of narwhals and an experiment that you can do at home!
Freshwater and Saltwater
In the Arctic regions, the physical and chemical differences between freshwater and saltwater ice impact hunting and travel. Knowing these differences is particularly critical for safety in places like Hudson Bay, where freshwater rivers meet salty ocean water. This lesson offers an interactive comparison of freshwater and saltwater ice, including a kitchen experiment with ice, information from multiple media, SIKU.org, and an interview with someone from Sanikiluaq. All you will need is your pen and paper, plastic containers or glass jars, table salt, tap water, toothpicks or a butterknife, food colouring, and a free account on SIKU.org. Enjoy!
This lesson plan explores the world of marine phytoplankton and their key role in the Arctic ecosystem. You will find beautiful microscopic snapshots, fascinating photos of algae stuck to the bottom of sea ice, and images of phytoplankton from space.
Arctic Food Webs
Watch this short lesson to learn about the different roles of species in an Arctic marine ecosystem, and to explore an Arctic food web! This lesson includes video footage of Arctic marine species and an interactive food web you can access from home!
Dive to Survive
Joel shows you some cool underwater footage and how some simple math and geometry can help you calculate the speed and energetics of the birds as they dive to survive the cold Arctic winter.
