SCIENCE VOCABULARY
Biology I
Introduction to Science Vocabulary


What is a bicycle?
What is a triangle?
 How


do you know?
If I say I just got a new monitor and
mouse, what am I referring to?
50 years ago…
Science Vocabulary
Science words are used to
facilitate meaning.
 Many science terms can be
broken down into word ‘parts’
 Most science terms come from two
ancient languages:
Greek
Latin

Science Vocabulary

Why would we want to have a
standard language?
*So scientists around the world
would know what other scientists are
referring to:
English: green plant
Spanish: planta verde
French: usine verte
German: grünes werk
Ukrainian: зелена рослина
Science Vocabulary - Greek
‘Biology’
can be broken
down into:
*Bio-  life (prefix)
*-Logy  the study of (suffix)
Biology
is the study of life.
Science Vocabulary - Latin
‘Bilingual’
can be broken down
into:
*Bi-  two (prefix)
*Lingu/o- tongue, language (root)
*-al  pertaining to (suffix)
Bilingual
means pertaining to two
languages
Chemistry Term:
 Endothermic

What does it mean?
‘Endothermic’ can be broken down into:
*Endo-  within (prefix)
*Therm-  heat (root)
*-ic  pertaining to (suffix)
Chemistry Term:
An endothermic reaction is one
that pertains to (taking) heat in.
 In other words… an endothermic
reaction is any chemical reaction
that absorbs heat from its
environment.

 Example
of endothermic reactions:
Baking bread, cooking an egg, boiling water
Chemistry Term:
 Exothermic

What does it mean?
‘Exothermic’ can be broken down into:
*Exo-  out, outside (prefix)
*Therm-  heat (root)
*-ic  pertaining to (suffix)
Chemistry Term:
An exothermic reaction is one
that pertains to (sending) heat
out.
 In other words… an exothermic
reaction is any chemical reaction
that releases heat into its
environment.

 Example
of exothermic reactions:
Rocket propulsion, human digestion & burning coal
Medical Example:
 Hypodermic

What does it mean?
‘Hypodermic’ can be broken down into:
*Hypo-  under or below (prefix)
*Derm-  skin (root word)
*-ic  pertaining to (suffix)
Medical Example:

A hypodermic needle injects a substance
underneath the skin.
Hypodermic needle
Medical Example:
 Dermatitis… What does it mean?
‘Dermatitis’ can be broken down into:
*Derm-  skin (prefix)
*-itis  inflamed or swollen (suffix)
Dermatitis means inflamed or swollen skin.
• In this case ‘at’ was added into the word.
• Sometimes when combining prefixes and suffixes, letters are added
or taken out to make the word pronounce better.
Prefixes
 We
can change a root word
simply by adding different
prefixes together
 kidney (root)
 Prefixes:
 Ren/o
 Peri

 around
Perirenal – surrounding the kidney
 Supraabove

Suprarenal-above the kidney
 Infrabelow

Infrarenal - below the kidney
Suffixes
 The
same can be done with
suffixes
 Cephal/o
 head (root)
 Suffixes:
 -ic
 pertaining to

Cephalic – pertaining to the head
 -adtowards

Cephalad – towards the head
 -algiapain

Cephalalgia – pain in the head
(headache)
Break it Down Now

Pneumonoultramicroscopicsilicovolcanokoniosis

WHAT THE HECK DOES THAT MEAN?
Break it Down Now





First, we come to the prefix (pneu-), or (pneumo-)
which means lung.
Next, is (ultra), meaning extreme, and microscopic,
meaning small.
Now we come to (silico-), which refers to silicon, and
(volcano-) which refers to the mineral particles that
make up a volcano.
Then we have (coni-), a derivative of the Greek word
konis meaning dust.
Finally, we have the suffix (-osis) which means
affected with. Now lets rebuild what we have
dissected:



Considering the prefix (pneumo-) and the suffix (osis), we can determine that the lungs are affected
with something. But what? Breaking down the rest of
the terms we get extremely small (ultramicroscopic)
silicon (silico-) and volcanic (volcano-) dust (coni-)
particles.
Thus, pneumonoultramicroscopicsilicovolcanokoniosis is a disease of the lungs
resulting from the inhalation of very fine silicate or
quartz dust.
That wasn't so difficult, now was it?
As the year progresses and you encounter words you
don’t understand:




Consult your list of prefixes, suffixes, and word roots for
their meanings!
Put the parts together to get the word meaning…
Read the sentence again to make sure your new found
meaning makes sense…
Begin to reap the rewards of being a more efficient and
effective reader with your increased knowledge of scientific
terms built from word parts!

WRITING SCIENTIFIC NAMES
Biology I – Honors
Scientific Terms

Many Greek and Latin
prefixes and suffixes are
combined to create
scientific terms.
 Zoology–
study of animals
 Cytoplasm – cell fluid

BUT… When creating a
scientific name for a new
organism, certain rules
must be followed.
How to write a scientific name:
Scientific names are always
represented by two parts:
 Genus name
 Species name
 The genus name will always come
first and is capitolized
 The species name will always come
second and is NOT capitolized
 Homo sapiens

Notice that it is UNDERLINED!
LAB: Fun with Prefixes & Suffixes

Part 1- Name your organism
 Each
row of students will get a
prepared numbered specimen
 Do
not shake bottles
 If any liquid gets on your skin, just wash your
hands
 Work
in groups of 2 when naming your
organism.
 Name your organism according to the
directions.
 Go
through #12… STOP at this point
 Write the scientific name (only) on your note
card and give to teacher.
