matter

anything that has mass and occupies space

physical properties

characteristics of matter that can be observed, measured, or described without changing the object

color

tell us what color an object is

shape

tells us how an object looks

texture

tell us how an object feels when touched

size

tell us if an object is big or small, long or short

mass

amount of matter in an object; measured using a balance; unit: gram (g) or kilogram (kg)

weight

how heavy an object is because of gravity; measured using a weighing scale

volume

the amount of space an object occupies

states of matter

solid, liquid, gas

solid

has a definite shape, volume, and cannot easily change shape

hardness

resists scratching, cutting, or breaking

brittleness

breaks or cracks easily

malleability

can be hammered into different shapes

elasticity

stretches and returns to its original shape

strength

with stands force without breaking

liquid

no definite shape, takes the shape of its container; has definite volume; can flow

gas

no definite shape and volume; spreads out to fill any container; can be compressed

matter

has mass and occupies space

mass

weighed using a balance

volume

amount of space on object occupies

describing

to state the features of the objects being observed

comparing

you tell similarities or differences

classifying

grouping them according to their common characteristics or properties

balance

used to measure the mass of objects

atoms

tiny particles that make up matter

molecules

groups of atoms

physical change

happens when an object is bended, pressed, hammered, or cut

chemical changes

change in the properties of matter and results in the formation of new substances
