Ice that forms in the polar oceans is an important driver behind the global climate. This ice is physically different from frozen precipitation in a number of different ways. In this brief inquiry activity, students make qualitative observations about two types of ice cubes and deduce ice composition based on their observations. This activity may serve as an introduction to
This activity is a way to create a cloud chamber in the classroom. A cloud chamber allows students to view "invisible" alpha particles emitted through nuclear decay. Alpha particles have a long history in nuclear physics--they are a helium nucleus and their emission during nuclear decay was one of the first ways we knew that atomic nuclei could
WHOI is the world's largest private, nonprofit ocean research, engineering and education organization. This site has information on oceans from climate to ocean life to ships and technology.
