What are the different kinds of thermometers and their uses?
Contributed by 1st grader Mackenzie and her mom Julie:There are circle thermometers which are like a clock and you read the numbers from left to right. There are stick thermometers that go under your tongue, your arm pit or other body parts. The numbers go from bottom to top. There are digital thermometers that can go in your ear, on your finger or other body parts. There are inside thermometers and outside thermometers to tell the general warmth/coolness of the space/environment. There are different scales - Fahrenheit and Celsius. Thermometers may be used to take a person's body temperature, to tell how warm/cold it is outside or in a room, to test whether food is cooked to a desired temperature to be safe.We hope we helped you.
