My goal with the CS magazine is that
you will become familiar

scientific vocabulary.
I do want you to
read for understanding
, but
I do not want you to memorize
these definitions.
You wi ll be able to
use the magazine and your definitions on the
test
.
For thi s first issue, I am gi ving you the definitions and I want you to copy them exactly l ike they are presented.
These are the types of definitions that I exp
ect you to come up after reading and getting context cl ues.
If you cannot find a definition, you may use your computer to fi nd definitions.
I wi l l have definitions for you to use if you need help, but you have to
try to fi gure out a definitions first.
To
be successful i n Current Science,
read
the magazine,
highlight
all the words on the list for the entire magazine.
Then go back,
re
-
read
and
define one article
at a ti me.
Skip lines
between definitions.
