Title: UNIT 3 FLUIDS
Course: 2024 Physics 3

In Unit 3, students will consider how a fluid’s internal structure and interactions define its macroscopic characteristics and how these interactions can be studied if they can’t be seen. Woven through this unit are essential principles, including an emphasis on representations and models and connecting related knowledge between fundamental ideas. Unit 3 utilizes familiar force and energy representations (free-body diagrams and energy bar charts) to describe static and dynamic fluids. As in previous Physics course, being able to identify and describe the relationships between physical quantities—and use these relationships as evidence to justify claims—is a critical skill when answering scientific questions. Students will once again be encouraged to sharpen their understanding of mathematics and the laws of physics by being asked to reason with equations to describe a phenomenon. Although its content is unique, Unit 2 presents thematic threads that weave throughout the course, including the interactions between systems and the conservation of fundamental quantities.
