MEASUREMENT
METRIC SYSTEM The METRIC SYSTEM is based on units of ten.
LENGTH Length is the number of units that fit along one edge of an object. .
UNITS When we measure, we use STANDARD UNITS.
DENSITY Density is the amount of matter in a given space; in scientific terms, density is the amount of mass in the unit of volume.
WEIGHT Weight is the measure of the pull of gravity between an object and Earth.
GRAVITY Gravity is a force of attraction, or pull, between al objects.
The inch (in. ), the pound (lb. ), and the ounce (oz. ) are part of the ENGLISH system.
What do scientist use? STANDARD METRIC SYSTEM
What are 4 metric units to measure length? CENTIMETER DECIMETER KILOMETER
WIDTH is the number of units that fit across the object.
AREA describes the number of unit squares that cover a surface. An easy way to find the area is to MULTIPLY its LENGTH by its WIDTH.
VOLUME describes the number of cubes that fit in an object or substance. How do you find the volume of a rectangular solid? MULTIPLY ITS LENGTH BY ITS WIDTH BY ITS HEIGHT
MASS is the amount of matter making up an object.
Which metric units are used to measure mass? MILLIGRAMS KILOGRAMS
The relationship between mass and volume is called DENSITY is the mass of matter in a given space.
How would you find the density of an object? DIVIDE ITS MASS BY ITS VOLUME
The density of a substance affects whether it FLOATS or SINKS. An object FLOATS if it is less dense than the substance in which it is placed.
TEMPERATURE affects the density of a substance.
OUNCES and POUNDS are English units for weight. .
