Have you ever been really cold in your classroom while everyone else was hot? Do you sometimes feel really warm outside, even though you are told that you need to wear a coat because it’s cold? The temperature your body senses does not always match the temperature that would be recorded by a thermometer. It is possible that on the day you felt warm outside, even though it was cold, you had been running around and were already warm. When you do this activity, you will see if previous conditions affect the ability of your hands to measure temperature.
In this activity, you will
Determine if touch is adequate to determine temperature.
Explain the need for a thermometer.
