The Infrared Thermometer is a non-contact, fast-responding, temperature measuring device. The sensor works by measuring the infrared radiation emitted by objects. For most objects, you simply point the sensor at the object and read its temperature. Here are a few example uses of the sensor:

• You can easily investigate skin temperature. Compare the temperature of your palm to the back of your hand, your forearm, or your foot.
• Demonstrate that most objects in the room are at equilibrium. What is the temperature of the table top that feels cold? Compare its temperature to the temperature of the wall, the floor, or a book.
• Measure temperatures of hard-to-reach objects such as heating and cooling ducts.
• Compare the surface temperatures of cars parked in the sun. Does color affect the surface temperature? Is the surface hot enough to cook an egg?
• On a sunny day, compare the temperature of asphalt, concrete, and grass.
