How can the ocean be colder than 0 degrees C, the temperature at which water freezes? As it turns out, the concentration of the particles (in this case, the ions from the salt) in ocean water lowers the temperature at which the saltwater will freeze. Students will learn how ocean water freezes at a lower temperature than freshwater by
This lesson is intended to have the students think about the animals of the Arctic and which ones they think are the largest. This will help with misconceptions of some animals being smaller than they think and you sneak in the scientific method and measuring skills while doing this lesson. Students will love actively participating and comparing themselves
During the 2007 Bering Ecosystem study, population sampling was done for seals by boat and helicopter. By using raisin bread and your students’ imagination you can create your own sampling of the Arctic populations of seals in the comfort of your classroom. Not to mention, clean-up is a favorite among students with this activity that mixes math with
