EXPERIMENTS WITH LIGHT
AND SHADOW
Grop: Naerulinnud
Age of children: 4-5 years:
The teachers:
Meeli Lugus, Hege Mardiste
Objectives:
A child will learn how shadows are made.
A child will learn how the shadows will
change depending the source of light and dis-
tance.
The child can make experiences to understand
how some materials let the light trough and
some not.
Tools: A flashlight, a projector, a carrier, a
white flax, dolls for shadow theater, a magni-
fying glass, a pencil, a piece of silly Putty,
varying in shape and pattern on the drinking
cups, a mirror, a toy.
A brief description of
the action: In this activity
children will understand how
the light travels, they will
make tests with flashlight to
see how the shadows will
change and what kind of ma-
terials the light will penetrate
or not. They will make
shadow theater and play a
game with shadows.
The action of the gear: Show the children a
picture of where people are on top of the
shadows. What is in the picture? How the
shadows occur? Show a picture of the two in
the natural landscape, where the one is the sun
up high and the other is the Sun already set-
ting. Kids will find the differences between the
pictures up. I have come with a flashlight, what
do you think, what we do with it today, offer?
Because we are the light and the shadows of
the images looked so now what do we do
some tests by using a flashlight. Turn the lights
off and the lights on the space remains the only
flashlight. Everybody will examine the source of
light that the flashlight makes.

Tests:
What happens if you put your hand in front of
the flashlight?
In the light path by making hand shadow can
be extended or shortened?
Also, have you noticed how the moving of the
Sun during the day? Let's do this now in a
flashlight, pen and using Silly Putty virtually.
We confirm the pen by using the Putty on the
floor of the stand. With a flashlight, imitating
the movement of the Sun, children can see
how the pen shadow becomes.
When is the shadow of the tallest?
When is the shadow of the most shorter?
What do you think, does the light make a
shadow behind every object or can it go
through some objects without leaving a
shadow? First, they will but drinking cups with
different patterns in front of the flashlight, then
mirror and magnifying lens.
Whether the light passing through the lens?
Does the light pass through both of the drinking
cups the same way?
What happens if a light hits the mirror? (Takes
back the reflection).
What shape will give the lens to the light?
(Flexes the light).
Because the topic is shadows, we will play a
game with them. They have to show flashlight
on to each other and then step on each other’s
shadows to win the game.
Lastly, children can play shadow theater all
together. They will move the objects in front of
the light source and will understand more
about the light and how shadows are made.
