ESTONIAN I LOVE SCIENCE! SCIENZE MAGAZINE FOR KIDS I LOVE SCIENCE! CHILDRENS PROJECT MAGAZINE | Page 6

SCIENTIST ANDERS CELSIUS
AND THERMOMETER
Group: Naerulinnud
Age of children: 4-5 years
The teachers:
Meeli Lugus, Hege Mardiste
Objectives:
The child shall examine the thermometer and its
principle of operation.
Kids will make different mathematical assign-
ments with the reading of the thermometer.
Tools: Different thermometers, two jugs, one for
cold and one for hot water. Pictures of the
scientist A. Celsius and his inventions.
The action: How can we make sure what kind
of weather is outside. Is it worm or cold
weather? How can we know do you have a
fever? (children´s answers) For this we have
different kind of thermometers in the world. Al-
ready in the older times scientists made many
different scaled thermometers, but it made a lot
of mess. Swedish scientist Anders Celsius in-
vented a thermometer that had a zero degree
6
A brief description of
the action: Kids examine
the researcher's invention
claimed. Find out how to
have the thermometer in
daily life to help. The
principle of the manifestos
of the thermometer. Solve
tasks of the thermometer
readings for comparison
what implemented the freezing of the water
and hundred degrees that implemented boiling
of the water. This was the thermometer that
people started later to call Celsius’s thermo-
meter (show the children picture of Celsius and
the thermometer)
Nowadays this is the thermometer that is
widely used around the world. His thermome-
ters always have a ‘C’ so people would under-
stand that this is his invention. Let’s see does
our thermometers have the same markings?
I have here many different thermometers, let’s
see why are they used for.
Let’s see what the thermometer is made of and
what parts does it contain. Thermometer has a
scale of numbers, then there is a container of
liquid and a small glass pipe where is possible
for the liquid to move up and down. When the
liquid gets warmer it will expand and move up
the small glass pipe, when the liquid gets
colder it decreases and moves down the glass
pipe.
Tools: Thermometer, 2 jugs for hot and gold
water.
Experiments: First the kids will get the ther-
mometers and will observe the room tempera-
ture. For the next step they will put the
thermometer in to the cold water and they will
see the liquid starting to go lower as it decrea-
ses inside, and then they will make the same
experiment with the hot water and see the ther-
mometer go up.
Tools: Small pictures of sun and moon. Small
items for counting.
Test: Sunday morning thermometer was sho-
wing +3, in the day time the sun was up and
thermometer went up for the evening +6. How
many degrees did the thermometer rise? (Kids
will count and set up the morning and the
evening result of the thermometer, they will
make comprising and will find a solution)
Test: Monday morning the temperature was
+5, it was raining it the daytime and in the
evening the temperature was risen +6 degrees.
How many degrees did the temperature rise?
Etc.
