A Golf Ball is MORE DENSE than a Ping Pong Ball
What is DENSITY?? A Golf Ball is MORE DENSE than a Ping Pong Ball What does this mean?

Density is the measure of the _______________ of a material
The ______________ of like atoms or molecules More than just the _____________of a substance, density includes _________________ an object takes up!! All substances have density including liquids, solids, and gases Bread slice and compacted bread in large flask of water

DENSITY Depends on: Mass usually expressed in ________
Volume: ___________________________________ FORMULA: __________________ Mass usually expressed in ________ Volume usually expressed in _____ or liters, etc.

What would take up more space. A kilogram of feathers…
What would take up more space??? A kilogram of feathers….. or a kilogram of steel?? ROCKS - pass around OR

“Compactness” Hot air balloon - Describe how a hot air balloon works. Defend your argument.

LIQUIDS The more dissolved solids in a solution, the __________________ (such as ocean water) Cold water in lakes tend to ______ (this creates a constant mixing of water, nutrients, and other substances) Straw solute Denser layers to less dense layers…..

What would happen???? Mercury density = 13600kg/m3
Lead density = 11340kg/m3 Sinking vial - make it float

Solids Ice vs. water…..

SOLIDS Ice is _____________ than water (which is why lakes and ponds have a thin layer of ice covering in winter, with water underneath) Various rocks, woods, metals have a characteristic density specific to that substance Beans/ping pong ball; Big jug of water in a pool Wouldn’t you like to have a bunch of THIS dense material?

Factors affecting Density
