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

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
