About This Chapter
Overview of Density and Buoyancy - Chapter Summary
These engaging and entertaining videos can be used by parents and teachers to supplement their middle school students' classroom physical science studies. Our easy-to-follow lessons are short and contain thorough explanations of density and buoyancy alongside related equations and examples from daily life. Each video is followed by a brief, self-correcting quiz to check understanding on the material covered there. The chapter is concluded with a multiple-choice test to ensure your student(s) retained the most important bits.
Chapter Lessons and Objectives
|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.|
