A laboratory is a specially designed room or building where scientific experiments are carried out. Each science subject has its specific laboratory. In this topic, we focus on Biology Laboratory as an example to illustrate how scientific investigations are performed.
A biology laboratory contains the following:
- Large windows and spacious design: To allow adequate air circulation and natural light, enhancing ventilation and visibility.
- Shelves: Used for keeping chemicals, apparatus, specimens, and biological models.
- Supply systems: Water taps, gas outlets, and electricity sockets to support various practical activities.
- Working benches: Where students and teachers conduct experiments.
- Emergency exit door: For quick evacuation in case of accidents.
- Preparation room: Where the laboratory technician prepares materials and stores equipment safely.
The following laboratory rules must be observed:
- Do not enter the laboratory without permission from the teacher or laboratory technician.
- Do not play, or run unnecessarily in the laboratory.
- Do not eat or drink in the laboratory.
- Do not use chemicals or handle apparatus or specimens without instruction from the teacher or laboratory technician.
- Any accident or damage of apparatus must be reported.
- Label chemicals and specimens to avoid confusion.
- Always keep flammable substances away from flames.
- Turn off water and gas taps after use.
- Never point the open end of the test tube to your fellow or yourself when heating.
- Never smell substances, specimens, chemicals or gases directly.
- Wash your hands with soap after the experiment.
- Clean the apparatus and benches after the experiment.
- Return the apparatus and chemicals to their normal position after use.
-
Presence of biological apparatus and specimens
Unlike regular classrooms, the biology lab contains equipment for studying plants and animals, including living and preserved specimens.
-
Workbenches and water sinks
It is usually equipped with workbenches for practical work and sinks for cleaning apparatus, which are not found in typical classrooms.
-
Microscopes and related tools
Biology laboratories contain microscopes and slides used to view microorganisms and cells, which are not available in other school facilities.
-
Chemical storage cabinets
Some biology labs store non-toxic chemicals used for experiments, kept in designated cabinets with safety labeling.
-
Safety equipment
Laboratories have safety items such as fire extinguishers, first aid kits, and emergency wash stations to handle accidents during practical work.
-
Charts and models
Biology labs are decorated with educational charts and 3D models showing human anatomy, plant structures, life cycles, and ecosystems, which help in visual learning.
