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!
