Introduction
dynamic, interdisciplinary study of the interactions of living and nonliving parts of the environment with a focus on human's impact
What is environmental science
changed by the person doing it
what is independent variable
anything that has mass and takes up space
what is matter
two or more elements chemically bonded to make a new substance
what is molecule
measurement of acid and base
what is pH
process of gaining knowledge about the natural world
what is science
part of the experiment that are not changed by the experimenter, but might change because of the independent variable
what is dependent variable
same type of matter
what is element
number of protons
what is atomic number
produces H+ ions in solution pH<7
what is acid
defined steps to research the world
What is scientific method
doesn't receive the experimental treatment
what is control group
smallest component of element
what is atom
protons and neutrons in an atom
what is mass number
produces OH- ions in solution pH>7
what is base

what is hypothesis
receives the new treatment
what is experimental group
positive charge
what is protons
same elements with different mass
what is isotopes
keeps the pH within a specific range
what is buffers
describe how elements of nature will behave under certain circumstances
