Add a baby to your model. So far, you have been measuring the temperature
of the air in the incubator. But what will happen to a baby? Get a small
object that can be your "baby." This can be a small plastic doll,
a blob of clay, a baggie full of water, or whatever you like. Think about
how to place it inside the incubator. Put the thermistor inside or on the
surface of the "baby." Predict the effect of this change on your
data. Measure how close to 37°C the incubator keeps this "baby."
Hint: you will need to take data for much longer. Do you see why?
