One of the most important indicators of our warming climate is the extent and thickness of polar sea ice. Currently satellites measure the extent of polar sea ice but it takes more sophisticated equipment aboard a low-flying plane to actually measure the thickness of sea ice. This lesson will show students how this is done.
As part of a migratory bird study conducted with my bilingual second graders in Washington, DC, the students in my elementary science class spent four weeks getting to know all about birds! We initially focused on birds that migrate from our Mid-Atlantic forests to the tropical forests of Central America (an area where many of them are from)
This lesson came out of a desire to connect the plankton research that I did during the 0902 Healy cruise with my young "researchers" back in Washington, DC. I wanted them to understand that plankton not only feed the Arctic but that much of the world relies on these little critters that come to life for us when we look
