2 Archimedes’ Story The crown has silver in it and gold is pure! How can I figure out if it’s real?What’s this? the water rises when I get in!!! Hmmm…The crown has silver in it and gold is pure!Same Weight and Volume?
3 Archimedes’ StoryWhen you place an object in water, the rise in water is due to ______ ___________.Density depends on 2 things, __________ and ___________.Density is the reason objects _________ or _________ in fluids.
5 DensityTo figure out the Density of an object, divide the object’s ________ by it’s __________.___________ is how much space something takes up.Density = Mass / Volume
6 M D V The Density Triangle Density = mass per unit volume Per means divide!Unit means a single amount.MDV
7 DensitySame VolumeDifferent MassDifferent VolumeSame Mass
8 DensityDoes greater volume or less mass make Diet Coke float? How do you know?
9 DensityIf an object is More dense than the fluid it is in, it will _________.If an object is Less dense than the fluid it is in, it will _________.If a block of wood has a mass of 200 grams and has a volume of 4 liters, what is its density?
