Scientists in Siberia are seeing trends of more severe and widespread wildfires. Larch seeds are dispersed by wind. Experimentation is currently underway to determine distances larch seeds can disperse from viable, mature larch trees. Students will explore how various types of seeds are dispersed to get what they need to survive.

Operation IceBridge is an aerial survey that measures both land and sea ice in the Arctic and the Antarctic. There are many reasons to monitor the polar regions. The cryosphere is essential in helping to maintain global climate. One important reason is to investigate sea level rise. Land ice can cause sea levels to rise, when it melts, by adding
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
