Short Description: PP. 35-42. Groups discuss ways to reduce the boiling temperature of water and present their best idea. After discussing each idea, groups select an approach, write a procedure, and follow it. Students find that water can boil well below it typical boiling temperature. They try to make sense of their observations and discuss their conclusions in their groups. Next, the teacher hands out a phase diagram of water and allows the students to study it and write a caption for it based on what they think it is. Through discussion, students learn about phase diagrams and use them to better understand their previous work with pressure and changes of state. Note: This is a 105 page PDF.
