Modeling the Trieste to Explore Density and Buoyant Force

摘要

Often we see students memorizing definitions for mass, volume, density, and buoyancy. And they are usually able to calculate density and buoyant force, but once they are able to apply these principles to a real-life situation, the concepts take on new meaning. In this activity, students use the context of the historic Trieste bathyscaph to measure mass and volume, to calculate density, and to build a working model of a submersible. After building the model, students develop hypotheses and test their model to observe it in action.
