STATIC
ELECTRICITY
Group: Naerulinnud
Age of children: 4-5 years;
work in small groups of children
The teachers:
Meeli Lugus, Hege Mardiste
Objectives:
Child will examine the materials/differences.
The child examines and uses adjectives that
describe the materials.
Quote: Patience leads to the goal.
Tools: For each child a plastic rulers, a piece
of paper for rip in half, a balloon, a patch of
woolly, small rolls of paper (with a diameter of
about 2 cm), disposable plastic bags Recycle
Bin, which is the cut in the 2-3 cm wide strips
(for making plastic rings), shelf or a book.
The action of the gear: You will definitely
have had an experienced in taking off a
sweater, it squeaks, may get the spunk and
hair are attached to it. It is static electricity.
This may occur for each of the object, but it de-
pends on how easily one or another material
that takes over. For example, the woolly mate-
rial frictional electricity takes the weight more
easily than if the cotton material.
Today we make with you a variety of experi-
ments with static electricity.

A brief description of the
action: In the activity the
children will learn about
the static electricity and will
make some experience.
They will learn that by
rubbing different materials
they can make a positive
charge of static electricity –
some materials are better
than the other materials.
First of all, one as an example of the teacher
shows the attempts. He touches the balloon one
of the child's hair (nothing happens). Then he
rubs the balloons with a woolly material and
shows what happened to the hair of the child.
Next, kids will make the tests:
Tools: a balloon, wool flannel, a piece of
paper
1. Tear the paper 6-7 small paper pieces, the
smaller the pieces of paper is, the more easily
they remain attached to the balloon. Rub the
balloon on the cloth, the more and better you
will rub the more sure it is that the balloon is
charged with static
electricity and the experiment will succeed. Tools: a plastic ruler, paper, small rolls of
paper (with a diameter of about 2 cm), woolly
fannel.
4. Rub the ruler and try to move the ruler
above the paper roll, so that paper roll would
start to move on. For this test to succeed, it is
particularly important that the paper roll would
be small and light, and a ruler fully rubbed.
Tools: a balloon, wool flannel, a book, or a
shelf.
2. Lift up the book and try to stick a balloon to
it, whether the balloon remains attached to
hang or not? Rub the balloon with the woolly
flannel. Try again to stick a balloon to the
book, who managed to rub the balloon
enough will make succeed the
experiment. Tools: a balloon, woolly flannel, disposable
plastic bags Recycle Bin, which is the cut in the
2-3 cm wide stripes (rings).
5. In this experience you need a help of a
friend. Friend rubs the cloth to the balloon and
the other rubs the strip of plastic bag with the
woolly rug. Both object shall be granted the
same charge of positive static electricity. Now
you can take the strip of plastic bag and but it
above balloon. The plastic strip should start
hovering above the balloon.
Tools: a plastic ruler, pieces of paper, wool
flannel.
3. Rub a ruler with the woolly flannel. If the
ruler is loaded with static electricity, place it
close to the pieces of paper and see what hap-
pens? Pieces of paper will start to fall, and at-
tached to the ruler down and jump back on
again, like begin as a dance.
