During Lesley Urasky’s expedition, “Glacial History in Antarctica”, the team collected rock samples which were taken back to the University of Washington to be dated using cosmogenic (exposure) dating. This method of radiometric dating measures the ratio of isotopes of Beryllium (9Be:10Be) produced by the interaction of cosmic rays with minerals in rocks. This lesson will introduce the student to
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
