Use this powerpoint presentation to present students with directions to make a 4 flap foldable to teach phase diagrams and the vocabulary associated with them. The following vocabulary is shown visually: melting, boiling, freezing, condensing, triple point, critical point, etc. Students take extra care to make their flip notes neat and accurate and it is a more engaging way to take notes. Some teachers let students use their flip notes on tests and quizzes. The slides can be edited to fit the way that you teach concepts.
