Physical properties
Any properties that can be observed using the five senses or can we 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 the shape of its container, like water or juice, but it has a fixed amount of space (volume), similar to how a solid stays the same size
conduct
It allows something like heat or electricity to flow or pass through it 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 easy or difficult it is to scratch a minerals surface
streak
The color of its powder when you rub it on a hard, rough Surface like a tile
tiles
The colored powder left behind one mineral is scraped across the hard surface.
Color
It’s what white reflects back to our eyes. Minerals are colored because the absorb some colors of light and reflect the rest.
Luster
How shiny a rock or mineral looks when light shines on it, like a mirror, or glassy, or even dull.( luster is a physical property used by mineralogists to help identify minerals).
Cleavage
How some minerals break along smooth, flat lines instead of randomly, like when you crack an egg.
Scratch test
Where you try to scratch a rock with different objects ( like a fingernail or a penny) to see if it’s 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 compulsion and the same properties.
Sediment
The “dirt and stuff” that settles to the bottom of liquids, or is carried then deposited by water, wind, or ice.
Sedimentary
Rock formed from compacted sediment.
Igneous
Rock formed from magma or lava
Metamorphic
Rock formed from existing rock; Heat and pressure cause the minerals to form new combinations or new crystals
