Beaker

The primary function of
a beaker is to hold and
work with liquids.
Graduated Cylinder

Graduated cylinders are
designed to make
accurate liquid volume
measurements.
Ruler

Instrument used to
measure distance.
Triple Beam Balance

The function of a triple
beam balance is to
measure the mass of
objects.
Bunsen Burner

The function of a
bunsen burner is to
heat substances.
Cover Slip

The cover glass is used
with a microscope slide.
The cover slip serves to
flatten objects being
viewed and also serves
as a barrier between the
object and the
microscope's objective
lens to keep the lens
clean.
Safety Goggles

Safety goggles are used
to protect the eye from
any foreign object.
Eye protection is a
priority in any science
laboratory setting.
Fire Extinguishers

Fire extinguishers are
required safety
equipment in all
laboratory settings.
Students must not
operate these devices
unless the student has
been instructed in its
operation and the
student has permission
from a teacher.
Flask

The function of a flask is
to hold and store liquids.
Flasks are good for
mixing substances with
little or no spillage.
Gloves

Gloves are used to
protect your hands.
Some gloves protect
against temperature
extremes while others
serve as a barrier
against harmful
substances.
Hot Plate

The function of a
hotplate is obvious.
Hotplates are used to
heat substances.
Microscope
Microscopes can
magnify usually
between 40 times to
1000 times, depending
on the brand and
model of the
microscope used.

Microscope Slide

The microscope slide is a
flat piece of glass used
for viewing objects under
the microscope.
Petri Dish

A petri dish is a flat dish
made of plastic or glass
with a cover that is
primarily used to grow
bacteria.
Test Tube

The function of a test
tube is to hold a small
experiment, which would
be used to conduct an
investigation.
Test Tube Holder

The test tube holder
obviously is designed to
hold test tubes.
Thermometer

The thermometer is an
instrument used for
determining temperature.
