Steps:
The children close their eyes for some time and then describe, what
they have seen. They think about how they can produce complete darkness, and
use the materials at hand in order to seal all cracks through which light
still falls. The more accustomed the children become to the darkness, the
more they realize that light penetrates through even the smallest cracks into
the room. After this, the children try to get light back into the darkness.
They
also see that light-coloured items (e.g. white masks) only become
visible if they are lit up by a source of light.

Scientific explanation (concerning step 1): With closed eyelids we
often see reproductions and otherwise a reddish-brown colour that is caused
by our eyelidsÂ’ skin and
blood vessels. Our eyes are highly sensitive to each beam of light.
But only after 45 minutes in the dark has the iris opened so far that it also
notices even minimal rays of light.
|
Possible Variation: The children play ghosts, lantern parade or the
like in the dark or in semi-darkness.
