6. conclusion
define science - ** VERIFIED ANSWERS **✔✔the systematic inquiry, through observation and
experiment, into the origins and structures and behaviors of our living and nonliving surroundings
what is the difference between a question, hypothesis, and prediction? - ** VERIFIED ANSWERS
**✔✔a question is the curiosity of a situation, a hypothesis is a proposed explanation for this
situation, and a prediction is the expected outcome of the hypothesis
what is the difference between a null hypothesis and an alternative hypothesis? - ** VERIFIED
ANSWERS **✔✔with a null hypothesis, there is no significant difference in outcomes between
tested groups, while an alternative hypothesis expects a change
, explain the difference between experimental, observational and comparative methods of science - **
VERIFIED ANSWERS **✔✔experimental is a test, observational is through watching, comparative
is comparing two things
what is the difference between a hypothesis and a theory? - ** VERIFIED ANSWERS **✔✔a
hypothesis is an explanation based on assumptions where a theory is a hypothesis that can be
confirmed by others and is widely accepted
what is the difference between an atom and an element? - ** VERIFIED ANSWERS **✔✔an atom is
the smallest unit of an element that can retain all the chemical properties of that element, where an
element is a substances that cannot be broken into simpler substances
how do atoms form molecules? - ** VERIFIED ANSWERS **✔✔through chemical bonding (ionic,
covalent, and hydrogen bonding)
what is an ionic bond? - ** VERIFIED ANSWERS **✔✔where electrons are transferred from one
atom to another
what is a covalent bond? what are the two types? - ** VERIFIED ANSWERS **✔✔where electrons
are shared between atoms
nonpolar (electrons shared equally) and polar (electrons shared equally)
what is a hydrogen bond? - ** VERIFIED ANSWERS **✔✔attraction between two molecules that
have an H bonded to a F, O, or N
what are four unique properties of water and why do these make water essential for life? - **
VERIFIED ANSWERS **✔✔water is an excellent solvent, water moderates the effect of temperature
changes, water forms ice, water can be basic, acidic or neutral
describe the pH scale - ** VERIFIED ANSWERS **✔✔
