Terms

undefined, object
copy deck
something that causes something else to happen
reactant
an organism that eats another organism
consumer
a change that you can see taking place physically, not a chemical.
physical change
it breaks easily (non metal)
brittle
an underground storage place for water, an underground lake.
aquifer
an organism that makes it's own food
producer
water that is found underground, no very different from an aquifer
ground water
has mass and takes up space
matter
ex. grass, grasshopper, bird, hawk
food chain
many atoms together
compound
it's flexible, not easily broken
ductile
an atom with a negative charge
electron
something that stays together but can be pounded on and not get broken..
malleable
a chart of elements/chemicals and their information
periodic table
the rate at which the food chain grows and functions
trophic lever
the cycle in which water goes from, evaporation, precipitation, condensation/transpiration.
water cycle
the control center of all cells.
Nucleus
an atom with 0 charge, it's neutral.
neutron
the after math of having a reactant.
product
the process in which bacteria from plants converts nitrogen (N, small 2) into usable nitrogen.
nitrogen fixation
converting nitrogen into a usable form. Nitrogen gets absorbed into the ground and gets into the plants, bacteria on the roots of the plants then convert the nitrogen into a usable form, an organism eats the plants and gets the nitrogen into their body, the nitrogen then exits the body of the organism by "waste".
nitrogen cycle
a hybrid of metals and non metals
Metalloids
a change that is by a chemical reaction
chemical change
something that conducts electricity, or has an easy transfer of energy/heat.
metals
an atom with a positive charge.
proton
1.) all elements are made of atoms. 2.)Atoms of the same element are exactly alike. 3.) atoms of a different element are different properties. 4.) Atoms are not actually changed by a chemical reaction, just rearanged. 5.) Compounds are formed when atoms combine. 6.)compounds are defined but the number, type and proportion of atoms, matter cannot be created or destroyed.
Atomic theory of matter
it is brittle, non mattleable, and is a poor conductor of heat/electricity/energy.
non metals
issues that have something to do with the environment.
environmental issues
groups in the periodic table
periods
