The purpose of this investigation is to understand the change that takes place when water condenses from a gas to a liquid, and how a change in pressure affects this transformation. Materials needed for the experiment include a large (2L) soda bottle, a squeeze bottle with a plastic hose, parking pens, construction paper, wooden matches, and tap water. The resource includes background information, a pre-activity exploration for students, teaching tips and questions to guide student discussion. This is the chapter 12 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The guide includes a discussion of learning science, the use of inquiry in the classroom, instructions for making simple weather instruments, and more than 20 weather investigations ranging from teacher-centered to guided and open inquiry investigations.
