Things are Heating Up

In this demonstration, students learn that heat makes air expand and rise, and learn how pressure systems are formed by observing the creation of a convection current. A large rectangular pan, a salad dressing bottle, a small latex balloon and water are required materials. The resource is part of the teacher's guide accompanying the video, NASA SCI Files: The Case of the Phenomenal Weather. Lesson objectives supported by the video, additional resources, teaching tips and an answer sheet are included in the teacher's guide.
