Study Notes
Biology and Laboratory Rules
- Biology is the detailed study of living things in the natural environment, encompassing structure, function, relationships, and interactions between organisms and their environment.
Branches of Biology
- Botany: the study of plant life
- Physiology: the study of the function and mechanisms in organisms
- Genetics: the study of inheritance and genetic variation
- Microbiology: the study of microorganisms
- Ecology: the study of interactions between organisms and their environment
Laboratory Rules and Safety Measures
- Emergency equipment: shower station, eye wash station, fume hood, laminar flow cabinet, biological safety cabinet
- Personal protective equipment: goggles, face mask, lab gloves, lab coat, handwash, lab shoes
- Harmful substances: chemicals with pH values between 5-9, organic solvents, substances with pH values < 5 or > 9
Waste Management
- Sharp wastes: syringes, needles, glass, scalpel
- Non-sharp wastes: gloves, tissue papers, petri dishes, plastic culture containers, and hardened agar
- Liquid wastes: broth culture, blood
- Animal carcases: organs and tissues
Laboratory Safety Rules
- Do not work alone in the lab without supervision
- Wash your hands before and after conducting experiments
- Clean your workstation using disinfectant
- Dispose of wastes according to Standard Operating Procedure (SOP)
Handling Chemical Spills
- Inform your teacher
- Declare the spill area as a restricted zone
- Prevent the chemical spill from spreading using sand
- Scoop up the chemical spill using appropriate equipment
- Dispose of the chemical spill safely
Handling Mercury Spills
- Inform your teacher
- Declare the spill area as a restricted zone
- Sprinkle sulphur to cover the mercury spill
- Call the fire and rescue department
- Dispose of the mercury spill safely
Safety Measures for Fire
- Stop work immediately and switch off all nearby power sources and unplug all appliances

- Call the fire and rescue department
- Do not panic and stay calm
- Do not recollect your belongings
Handling Glass and Chemicals
- Be cautious when handling hot glassware
- Report any damaged equipment to teachers immediately
- Keep flammable substances away from fire sources
- Do not touch, taste, and smell chemicals directly
Graphs and Charts
- Types of graphs: line graph, bar chart, histogram
- Line graph: used to show the relationship between manipulated and responding variables
- Bar chart: used to present data using vertical bars that are not attached to each other
- Histogram: shows the visual distribution of data and frequency of a value in a data set
