materials you can see through them (transparent)
light can pass through the materials
slate tiles

material melting point
boiling point
tensile strenght
pull a material until it snaps & measure the force required
material

have the same property, even tho nail is lighter
density
property that describe heaviness for its size
we might pack a tv

chemical properties
materials have other properties
new substances are formed
absorbent materials
chosen for certain uses
ex. paper towels for liquid spills
