b. Change over time in effort species survive
, What are the parts of the scientific method? ANS - 1. Make observation and question
2. Hypothesis (educated guess that is testable)
3. Make prediction based upon hypothesis and test it.
control- independent variable not factor(Placebo)
Experimental- independent variable tested on
4. Make new predictions and test based upon results
What is inductive reasoning? ANS - facts accumulate until amount of information allows statement
to be made.
what is deductive reasoning? ANS - begins with a general statement that leads to a conclusion.
what is information literacy? ANS - ability to recognize what you need to know, local relevant info,
evaluate (using SM), apply to a problem and then communicate effectively. .
what is an element? ANS - the smallest unit that retains the unique chemical properties of that
specific type of matter.
what is an ion? ANS - an atom or molecule with a net electric charge due to the loss or gain of one or
more electrons
what are the three types of bonds? ANS - ionic
covalent
polar covalent
If the electrons are shared by the atoms involved in the bond it is a? (marriage) ANS - covalent bond
