Study Notes

Beaker

Cylindrical glass or plastic vessel for holding liquids.
Multi-purpose; used for chemical reactions, measuring, and heating liquids.
Volume measured in milliliters (mL) or liters (L).
Handle with care; report accidents to teacher immediately.

Erlenmeyer Flask

Conical shape with a cylindrical neck and flat base.
Ideal for mixing and heating solutions.
Transport using tongs (if heated) or hold at the neck.

Goggles

Protective eyewear covering the eyes during experiments.
Prevents foreign substances from entering the eyes.
Report any eye exposure to the teacher for proper response.

Graduated Cylinder

Transparent cylinder with finely divided markings for volume measurement.
More precise than beakers or flasks for liquid volumes.
Measure in milliliters (mL); should be placed on a flat surface for accuracy.

Pipet

Slender tube, typically 12 to 24 inches in length.
Designed for distributing precise small volumes of liquid.

Microscope Slide

Thin glass piece (75 by 26 mm) for holding specimens for microscopy.
A cover slip can be used to protect and observe the specimen.
Report any broken or chipped slides to teacher for proper disposal.
Light microscopes used in classrooms; electron microscopes provide higher magnification.

Thermometer

Laboratory tool for measuring temperature accurately.
Can be partially or fully immersed in the substance being measured.
Temperature measured in Celsius (°C); boiling point of water is 100 °C, freezing point is 0 °C.

Test Tube

Container for handling chemicals, especially in qualitative experiments.
Suitable for heating small amounts of liquids or solids with Bunsen or alcohol burners.
Held by neck with clamp or tongs; can be placed in a rack.

Petri Dish

Shallow glass or plastic dish used for culturing bacteria and microorganisms.
Contains agar to evenly suspend nutrients for microbial growth.

Ruler

Instrument for measuring lengths in metric (centimeters, millimeters).
1 meter = 100 centimeters, used for accurate length measurements.
