This instructor guide provides background material for a two-part activity in which students observe convective currents in water and learn that air can behave as as a fluid. Students will understand that temperature changes can cause density changes in water, learn that the same phenomenon happens in air, and understand that temperature-driven density changes will produce currents in a fluid medium. The student guide has an overall description of the activity, a list of materials, the procedure and observations and questions for both parts. Materials provided in the instructor guide include learning goals, alignment to national standards, grade level/time, details on materials and preparation, procedure, assessment ideas, and modifications for alternative learners.
