Welcome back Minions!!!

Welcome back Minions!!!Warm-up is on the board

QUESTION!!!Which of the following has more mass?

1 Pound of Feathers16 ounces of Sand1/2000 Tons of ChocolateAnswer!!!They all weigh the same!!!

16 oz in a Pound2000 Pounds in a Ton(So 1/2000 of a ton is a pound!)

(Trick-trick!!! NEENER!!!)Weight and MassWhat is WEIGHT???Weight is the measure of the force of gravitys effect on an object!

What is MASS???Measurement of the amount matter in an object!Units of MassScientists use a system called:International System of Units(or S.I.)

French: Systme international d'unitsUnits of MassSI unit of mass is the KILOGRAM

Sometimes you will use grams instead.

1000 grams = 1 kilogramVisual effect time!!!Check this out!!!Visual Effect Time2 Buckets1 Cola1 Diet ColaBoth cans same volume.Regular sinks, butDiet Floats!

How did this happen?Perhaps we should look at the volume.

Volume = Length x Width x Height

HmmmPerhaps we can check the mass of each canWhoa!The Volume is the same, but the Mass is different.

This is where DENSITY is applied.

What is DENSITY?More Math!!!Density =

Density Relates to the mass of an object within a given volume.

One more nifty thing to seeIs density limited to solid objects?Gas?What is the difference betweenBalloon you inflate using your lungsBalloon you inflate using a helium tank.

DENSITY OF THE GAS!!!

Liquid???What is this upon the counter???ReviewWhat is weight?

1) It is the measurement of the amount matter in an object.2) It is the measure of the force of gravitys effect on an object.3) It is patiently standing by for something to happen.4) None of the above.

ReviewDensity is

1) How dense an object is.2) Calculated as Mass divided by Volume.3) Relates to the mass of an object within a given volume4) All of the above.
