This activity mixes a suspenseful scene from a movie about a volcano with student formulated answers to open-ended questions about the validity of science. In the activity, students act as film consultants to determine if a massive lava flow could actually be stopped by water being sprayed onto it. Students apply their knowledge about heat to determine their answers. Links to student materials include a worksheet that presents known and unknown variables directly related to the film. An example of a known variable is the water flow rate from a fire truck, while an example of an unknown variable that students must figure out is the temperature of the water. In a pdf document, teachers can find additional information about a real-life attempt to slow the spread of lava from a volcano that erupted in Iceland. A Cornell Science Inquiry Partnerships Fellow created and piloted this activity. Copyright 2005 Eisenhower National Clearinghouse
