1. Thermometer (Overview)
Used to measure temperature
Units of measure: Celsius (0C), Fahrenheit (0F), Kelvin (K)
We generally always use Celsius (0C)
Relies on the expansion and contraction property of fluids – this is why the fluid (alcohol) rises as the temperature goes up and falls as the temperature goes down

2. Thermometer (How to Use)
Similar to when using a graduated cylinder, determine the value of each graduated marking, or line, found on the thermometer – knowing this will help you determine the temperature.
Lower the thermometer into the object/substance while holding the top of the thermometer. Be sure to not allow the bulb of the thermometer to sit on or touch the container holding the object/substance.
Measure the temperature of the object/substance by reading where the top of the red liquid (alcohol) aligns with the appropriate scale. This should be done at eye level.
