Beaker
 Cup-like container
with graduated
markings (known
scientific
measurements)…
Flask
 Modified container that
can be used for mixing
chemicals. Can also be
used for the temporary
storage of chemicals.
Test tube:
 Cylindrical glass tube
used for conducting
experiments.
Test tube rack:
 Holds test tubes securely
before, during, and after
experiments.
Microscope Slide:
 Thin rectangular piece of
glass for a specimen to
rest upon while viewing
with a microscope.
Cover slip:
 Protective cover placed
upon a microscope slide
to keep the viewed
material stationary.
Depression slide:
 Specialized microscope
slide that has a small
depression for viewing
material too large for
traditional slides. Also used
for viewing live specimens.
Graduated cylinder:
 Provides accurate
measurements of liquids
used in the lab in
increments as small as 1
milliliter (ml).
Test Tube Brush:
Used to clean test tubes
before and after each
lab.
Safety Glasses (Goggles):
Worn to protect the eyes
from flying debris and
sprayed fluids during
labs.
Eye dropper:
 Allows a
controlled
dispensing
of liquids
during
experiments.
Stirring Rod:
Thin piece of glass
used in labs for
stirring liquids and
solids together.
Dissecting Tray:
 Metal tray with a wax
bottom upon which a
specimen is explored and
experimented during labs
involving dissection.
Probe:
Blunt thin tool used
during dissection that
allows for separation
of tissues… without
causing excessive
damage.
Dissecting
Needle:
Fine-tipped probe
used to maneuver
parts of a dissection
specimen during labs.
Forceps:
Also known as
tweezers, used for
grasping parts of a
specimen during
dissection.
Petri Dish:
 A two part dish
commonly used with
agar for growing microorganism cultures for
study.
18. Microscope:
Lab equipment that
uses lenses, mirrors,
and light to magnify
items not seen with
the naked eye.
Compound Light
Microscope:
 The kind we
use in class.
Ours can
magnify up to
400 times
(400X).
Scanning Electron
Microscope
 Can magnify up
to 100,000 times
(100,000 X)!
 Produces a 3-D
image of the
surface of the
object.
Scanning Electron
Microscope
 Bounces
electrons off
the surface of
the specimen.
Scans a 3-D image of the
outside of the specimen:
 Black Widow Spider
claw (500X)
Transmission Electron
Microscope
 Can magnify up
to 200,000 times
(200,000 X) !!
 Electrons pass
through the
specimen.
 A flat image is
produced that
shows the
specimen’s
insides.
Transmission Electron
Microscope
Heart muscle cells seen with
a transmission electron
microscope at 20,000 X.
19. Thermometer:
Measures
temperature using
the Celcius (ºC)
scale.
20. Triple Beam Balance:
Measures mass of an
object, item, or specimen
using counter balances
(known masses). Mass
is measured in grams (g).
