TOPIC: Archimedes' principle and buoyant force.

1. Choose a discussion topic that uses physics topics covered in this module. Consider one of the following as good topic "starters" for discussion: (i) What were your "Aha!" moments as you worked through the material? (ii) How does this module's content relate to your professional career? Personal life? (iii) How does this module's content relate to current events? (iv) Did you more deeply explore a topic only covered lightly in the course materials? What did you discover? (v) What concepts (learning objectives) did you struggle with? What resources helped you overcome this hurdle? Do not post homework problems.
2. Engaging paragraph initial post that ties one or more of the module's concepts to the real world. The paragraphs should address the following points:
   • Paragraph 1: Describe the physics concepts/topics you have chosen to discuss from this week's module, including, as appropriate, a reference to this week's readings on the topics, terminology with definitions, units, conventions, etc.
   • Paragraph 2: Summarize one or more impacts of the physics concepts to everyday life or aviation.
   • Paragraph 3: Either: (i) provide a real example, e.g., from an article or documented report of the aviation impact of this physics concept, or, (ii) give "your take" on the relevance and importance of this topic from your own perspective, by providing personal points of view or related experiences.
