Study Notes
Laboratory Equipment
- A graduate cylinder is a type of laboratory equipment used to measure the volume of a liquid accurately, with markings on the side to indicate the volume.
Types of Observations
- Qualitative Observations: These involve describing an event or phenomenon using words, such as colors, textures, and smells, without measuring or quantifying it.
- Quantitative Observations: These involve collecting numerical data, such as measurements, counts, and percentages, to describe an event or phenomenon.
