New moon
the first phase of the moon in this phase the moon is completely dark since we cant see the side that the sun is shining on.
Crescent moon
The second phase of the moon in this phase we can see sunlight reflecting off only about one quarter of the moon’s surface that faces us.
Quarter moon
The third phase of the moon in this phase we can see sunlight reflecting off half of the moons surface.
Gibbous moon
The fourth phase of the moon in this phase we can see sunlight reflecting off 3 quarters of the moon’s surface that faces us its not a full moon yet but its getting there.
Full moon
The 5th phase of the moon in this phase we can see sunlight reflecting off ALL of the moons surface facing us in this phase of the moon appears round and completely lit up.
lunar cycle
the eight phases of the moon. its 29 1/2 days long.
axis
an imaginary line an object turns around.
day/night (24 hours)
PM-afternoon -after 12 lunch time.AM-morning time before noon -asleep and when you first go to school.
Physical properties
any property that can be observed using the 5 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 of its container.
Liquid
Some thing 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 are made up of rocks.
hardness
How easy or difficult it is to scratch the minerals surface.
Streak
The color powder when you rub it on a hard rough surface like a tile.
Tiles
The left over colored powder when a mineral is scratched across a hard surface.
Colors
It’s what light reflects back to our eyes Minerals are colored because they absorb some colors of light and reflect off of metal.
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 mineralogist 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 finger nail or a penny) to see if it’s hard or soft.
Rocks
a naturally formed combination of minerals and other naturally materials.
Minerals
a solid naturally formed substance that always has the same composition and the same properties.
Sediment
