physical properties
any properties that can be observed using the five senses or can be measured without changing the matter.
weight/mass
weight -how heavy an object is [mass is how much stuff (matter) something is made of)
solid
a state of matter that maintains its own shape instead of conforming to the shape of its container.
liquid
Something that can flow and takes shape of its container like water or juice but it has a fixed amount of space (volume) similar to how solid stays same size
Conduct
It allows something like heat or electricity to flow pass through easily
Heat
Energy that moves from something hot to something cold a form of energy.
Minerals
A substance found in nature minerals make up rocks
Hardness
How easily or difficult it is to scratch a minerals surface.
Streak
The color of powder when you rub it on a hard, rough surface like tile.
Tiles
The colored powder left behind when a minerals is scrapped across a hard surface like ceramic tile, which helps identify the miner by its “streak” color.
Color
It’s what light reflects back to our eyes. Minerals are colored because they absorb some colors of light and reflect the rest.
Luster
How shiny a Rick or mineral looks when light shines on it, like a mirror, or glassy,or even dull. (luster is a physical property used by mineralogist to help identify minerals.)
Cleavage
How some minerals break a long smooth,flat lines instead randomly, like when you crack an egg.
Scratch test
Where you to scratch a rock with different objects (like a finger nail or a penny) to see if its hard or soft.
Rocks
A naturally formed combination of minerals and other natural materials.
Minerals
a solid naturally formed substance that always has the same composition and the same properties.
Sediment
The “dirt and stuff’ that settled to the bottom of liquids or is carried and then deposited by water,wind,or ice
sedimentary
rock formed from compacted sediment
igneous
rock formed from magma or lava
