What: Building a Laterna Magica
|
|
Preparation:
Material: Canvas, book with
instructions, scissors, pens, sticky tape.
Laterna Magica: Cardboard
box and tube, crepe tape, sellotape, carpet razor, gold foil, magnifying
glass, torch.
Film:
Foil, foil pen, cardboard strips.

Steps:
Together with the children
the nursery school teacher regards a sketch that shows how to build a Laterna
Magica. She discusses the function of a Laterna Magica with the children and
refers to its connection with the cinema and today's television. With the
assistance of the nursery school teacher the children think about how they
can build a
Laterna Magica by using the
material at hand.
Steps for building a
Laterna Magica:
· Use a cardboard tube to draw a circle on the back and front of a cardboard box
· Carefully cut out the
circles
· Cut a slot into both
sides. Later the film strips will be pulled through
· Push a torch into the end
of the cardboard tube
· Fasten a magnifying glass
to the opposite side of the tube
· Glue a foil on a
rectangular strip of paper (= film strip). The children paint a picture
story on the film strips.
It is important that only the centre is painted. The children experiment and
mutually show their "film stories".

Scientific explanation:
The magnifying glass serves
as lens and the torch as
source of light for the
handpainted films. By means of the magnifying
glass the enlargened
pictures can be projected on a canvas.
|
Possible variation:
Instead of the torch a
battery operated lightbulb can be used as source of light (electric circuit
run see: electricity).
|
|
Note!
The source of light must be
in the focus of the magnifying glass, so that
the "pictures"
are recognizable.
