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.
