## Chapter Lessons and Objectives

Lesson Objective
What is Density? - Explanation & Examples Our instructors define density as a relation of a sample's mass to its volume.
How to Calculate the Density of Solids or Liquids Students learn to apply the mass-volume calculation to regular and irregular units.
What is Buoyancy? - Explanation & Equation This video introduces to the formula made famous by Archimedes that measures an object's buoyancy as a function of the fluid it has displaced.
Predict Whether an Object Will Float or Sink: Understanding Density Here your student learns to tie everything together to evaluate the qualities of an object and a fluid to determine how they will interact.
