Exploring Buoyancy and Floating Objects: A Hands-On Activity

Dive into the world of buoyancy and fluid dynamics with this engaging activity. Learn about Archimedes' principle, density's role in floating, and Pascal's and Bernoulli's principles. Discover how objects like rocks, potatoes, and paper clips float or sink. Explore the concepts behind the buoyant force and the physics of floating objects. Watch Mythbusters in action testing buoyancy myths and understand pressure units like pascal. Engage in interactive discussions to enhance your understanding of these fundamental principles of physics.
