The science laboratory

The science laboratory
cientists experiment in a laboratory. The science laboratory is different from
other classrooms in the school. It is filled with a range of equipment to help
you undertake scientific investigations.

Drawing laboratory equipment
Scientific drawings can be used in laboratory reports
to show how equipment was set up. It is important for
the drawings to be clear and easy to understand.
When drawing scientific diagrams, you should:
• always draw in pencil
• use a ruler to draw straight lines
• label the equipment drawn
• draw only a cross-section of the equipment
• not put lines across the top of glassware.
Here are some ideas for simplifying scientific
diagrams.
REMEMBER
1. What is the purpose of each of the following
pieces of equipment?
(a) Heatproof mat
(b) Evaporating dish
(c) Test-tube rack
(d) Retort stand
2. Give five examples of equipment used when
heating objects.
3. Give five examples of equipment used with
liquids.

to conduct an
experiment?
Identify the equipment
shown in the diagram
at right.
Provide examples for each of the following groups
of laboratory equipment.
(a) Containers
(b) Objects used to pick up equipment
(c) Objects used to hold equipment in place
(d) Objects used to support other equipment
(e) Objects used to protect the user or equipment
Look at the diagram below of the equipment used
to evaporate salt from a salt solution.
(a) Draw a scientific diagram of the equipment
using the tips on this page.
(b) Label all the equipment.
:
Filter funnel and filter paper
• Use a filter funnel when pouring from a bottle or
container without a lip.
• Never put wooden test-tube holders near a flame.
• Always turn the tap on before putting a beaker,
test tube or measuring cylinder under the stream
of water.
• Remember that most objects get very hot when
exposed to heat or a naked flame.
• Do not use tongs to lift or move beakers.
