Laboratory Thermometer
This is the temperature range of a standard laboratory thermometer.
What is –10°C to 110°C?
This is the unit used to measure temperature in most science classes.
What is degrees Celsius (°C)?
This is the temperature range of a clinical thermometer.
What is 35°C to 42°C?
This thermometer is best for measuring human body temperature.
What is the clinical thermometer?
This part of the thermometer must remain in the liquid when measuring temperature.
What is the bulb?
This thermometer is used to measure the temperature of solutions or experiments.
What is a laboratory thermometer?
This instrument is used to measure temperature.
What is a thermometer?
This special feature inside a clinical thermometer traps the reading.
What is the constriction/kink?
This thermometer is best for measuring hot liquids like water on a Bunsen burner.
What is the laboratory thermometer?
You must never let a thermometer touch this part of the beaker when heating water.
What is the bottom of the beaker?
This structural feature is missing from a lab thermometer.
What is the constriction?
This term means “how hot or cold something is.”
What is temperature?
This type of thermometer should never be placed in hot water.
What is a clinical thermometer?
This is one structural difference between the two thermometers.
“clinical has a constriction, lab does not”
“ranges are different”
“bulbs may be different sizes”
You must do this before and after using a clinical thermometer.
What is sanitize/clean it?
This limitation means you must read the thermometer while the bulb stays in the substance.
What is “the liquid falls immediately when removed”?
This thermometer has the wider temperature range commonly used in experiments.
What is a laboratory thermometer?
This is one advantage of a clinical thermometer.
What is “gives precise body temperature” OR “easy to read”?
This is one safety difference when using the two thermometers.
clinical cannot be used in hot liquids”
“lab thermometer must be read while in the liquid”
This safety rule explains why you must keep your face away from a hot beaker while reading temperature.
What is “to avoid burns or splashes”?
This is one advantage of a laboratory thermometer.
What is “wide temperature range” OR “good for experiments”?
This boiling point makes a laboratory thermometer necessary when water is heated.
What is 100°C?
This is one limitation of a clinical thermometer that makes it unsafe for experiments.
What is “narrow range” OR “breaks in high heat” OR “not for liquids”?
This difference explains why a lab thermometer is not accurate for measuring body temperature.
What is “the absence of a constriction makes the reading fall quickly”?
This is one safety rule for handling laboratory thermometers around hot liquids.
“Hold upright,”
“Do not leave in boiling water unattended,”
“Read at eye level,”
“Avoid sudden temperature changes.”
