Analysis

1. Your skin's sense of temperature and a temperature sensor seem to measure differently. Is one more correct than the other? Explain.
   
   
2. Your feeling of temperature can change when the measurement of temperature does not change. For example, although the moving air is the same temperature as the still air, it feels colder. How can you explain this?
   
   
3. If you were doing a science experiment, which would be better for measuring temperature -- using your finger or a temperature sensor? Why?
   
   
4. Animals in cold climates have heavy coats. Water birds have lots of oil in their feathers. How do your experiments explain why these features help the animals stay warm? Hint: think about how moving air feels colder than still air, and water feels colder than air.
