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
Beacon Valley is recognized by scientists as one of the most Mars-like environments on Earth. This lesson plan was created so that students could have the opportunity to examine the same landforms that scientists use to study the processes that operate in both of these extreme environments. There are two parts to this lesson. Teachers may choose to
