Mass is measured in grams, kilograms, pounds,
Length is measured using Ruler, meter stick or tape
measure.

Is the amount of space an object takes up
![Page 16: Thursday September 26](https://reader030.fdocuments.net/reader030/viewer/2022032709/56813023550346895d95a873/html5/thumbnails/16.jpg)
What is density?
The amount of mass a material has in a given volume.
![Page 17: Thursday September 26](https://reader030.fdocuments.net/reader030/viewer/2022032709/56813023550346895d95a873/html5/thumbnails/17.jpg)
How are mass, volume and density different?
Mass is the amount of matter in an object.
Volume is the space the object takes up.
Density is the amount of mass in a given volume.
![Page 18: Thursday September 26](https://reader030.fdocuments.net/reader030/viewer/2022032709/56813023550346895d95a873/html5/thumbnails/18.jpg)

Give examples of density.
IS THE AMOUNT OF MASS A MATERISAL HJAS IN A GIVEN VOLUME.
FLOAT DON’T FLOAT
ICEBERGS FLOAT BECAUSE SOLID ICE HIS LESS DENSE THAN LIQUID WATER
HYDROGEN IS USED TO INFLATE WEATHER BALLOONS BECAUSE IT IS MUCH LESS DENSE THAN AIR.
DENSITY OF WATER: 1 GRAM/CUBIC CENTIMENTER
