Preparation:
Torches, cardboard cylinders
|
Steps:
On a table the children find a torch and a large cardboard cylinder.
They think about what they can do with these two items.
The children find out, what happens (and / or comes out at the other
end) if they shine a torch into the cylinder in a dark room. They see that
the ray of light which is directed into the cylinder at one end is not
visible in the dark at the other end when looked at from
the side.
The children find the light on the wall or the ceiling and try to
catch it with their hands and make it visible. They recognize with
the help of the nursery school teacher that light must meet a surface
or dust particles, in order to become visible.
