For the final lesson of Chapter 11, students conducted the”cloud in a bottle” lab. They added warm water to two-liter bottles and then filled the bottles with smoke. By squeezing and releasing the bottles, students observed cloud formation. They repeated the experiment with bottles filled with cold water and without water and made observations on the Lesson 62 Worksheet. The Lesson 62 PowerPoint is available here as a resource. In place of homework, students were encouraged to prepare a page of notes to use for the Chapter 11 Quiz tomorrow. Pictures of the whiteboard, including a list of key notes to take for the quiz tomorrow and some thinking about warm and cold front interactions.
