Activity:
The students lay for a moment, hand on the bench and then observed using a thermal camera created by the thermal footprint and its gradual disappearance. Similarly, one can observe the difference in the track, which leaves a shoe vs. a foot in a sock vs. barefoot foot. It also can be observed, at which the chair is just sitting.
Questions for discussion:
What is the basic assumption that was found by a man using a thermal imager from a helicopter? In the corner of the eye, because it best reflects the internal temperature of the body.
Something extra:
Detective game: kids can go after the heat footsteps of a thief or after a cold footsteps of the zombies. Which way did he go? Where to sit? What tool he had in his hand?
Traces of the easiest to prepare using a hot water bottle and an ice gel. Watch out, the traces disappear quickly!
Example from practice:
The fire department upon arrival to the car accident control the temperature of the seats, so find out whether any of the passengers as a result of shock left the scene of the accident.
