What’s it about?

Heat is a form of energy. Ambient heat can be measured by a thermometer and this measurement is called temperature. The normal temperature of human beings is 37.4 °C and is always kept constant by our bodies, no matter what the ambient temperature is. In this science experiment we will test how subjective the feel of temperature is to our bodies:

How does it work?

Unfortunately, this section is only available in the e-book version of the project.

What the above science experiment illustrates is that what we perceive around us, is to a large extend based on a previous experience we had. The fact that you perceived the centre bowl of water as both hot and cold on separate occasions has mainly to do with the temperature your hand experienced earlier in the other hot or cold bowls of water.
