    Study Notes

    What is a Thermometer?

    • A device used to measure temperature, which is how hot or cold something is.
    • Can measure the temperature of different things, such as the air outdoors or something being cooked in the kitchen.

    Scales of Temperature

    • Temperature is measured in degrees.
    • There are two different scales for measuring temperature: Celsius and Fahrenheit.
    • It's important to check which scale is being used when reading a thermometer because there are big differences between the scales.

    Reading a Thermometer

    • Most thermometers use marks and an arrow, or a liquid that rises up to a line, to show the temperature.
    • Increments on a thermometer refer to the numbered marks, such as fives or tens, which make the thermometer smaller.
    • To read a thermometer, determine the increment, then count the little lines between the increments to find the temperature.

    Understanding Increments

    • Increments can be counted by twos, fives, or tens.
    • Typically, thermometers have lines that stand for single digits or twos.
    • Count the little lines from one increment to another to determine what they stand for.

    Determining the Temperature

    • To find the temperature, look at the arrow or liquid line of the thermometer.
    • If it points to an increment number, the temperature is easy to read.
    • If it points to a little line, go to the lower number increment and count up, being careful to remember what the lines stand for.
