Hot and Cold Temperature Unit Three

What is Temperature? Temperature is a measurement of how hot or cold something is. We use a _____________ to measure temperature. Thermometers measure temperature in a unit called Celsius. thermometer When the red liquid in the thermometer goes up, the temperature is getting warmer. When the red liquid in the thermometer goes down, the temperature is getting colder.
