Volume- Meniscus
Meniscus is the curvature of the liquid in the container
Need to get eyelevel with liquid and read the low point of the meniscus as seen here
This can be a source of error if not read properly
Time
• Units of the day• How long or short
something takes; events in the past, present and future
• Measured with a stop watch or clock
• SI Unit is seconds• Often need to consider
significant figures- fractions of a second
Temperature
• How hot or cold a material is; the average kinetic energy of a material
• SI Unit- Celsius, Kelvin• Tool used- thermometer
