[ ]    Teaching Videos: Density & Buoyancy - Chapter 5 // Earth Science YouTube Channel Playlist: ESA - Density(Video Homework -- 12 Secret Codes ) 6:59 Density #1: Basic Concepts -- by Mr. Clauset (1) How density is a measure of its mass divided by its volume. (2) Determining density by measuring volume using a ruler or by water displacement 12:07 Density #2: Word Problems -- by Mr. Clauset (1) Using the density formula (D=m/v) (2) Using the volume formula (V=l*m*h) (3) Using the idea of density to solve a puzzle 13:39 Density #3: Buoyancy & Fluids -- by Mr. Clauset Discussion of buoyancy in liquids and gases. Objects displace water as they sink or float. Water "buoys up" objects.   13:07 Density #4: Properties & Liquids -- by Mr. Clauset Density is mass / volume. It is not color or volume or mass alone. Some objects that will float in water will sink in oil. 3:04 Density #5: Suspension -- by Mr. Clauset Objects that are suspended in a liquid have the same density as the liquid. Suspension is another term for "neutral buoyancy."
