ABOUT WARM IN WINTER
Brrr - it's winter and you're starting to shiver from the cold. Shivering
makes your muscles move, which warms you up. But only for a while! Shivers
are a sign that you need to get out of the cold!
How do animals stay warm in the winter? When a bird gets cold it will puff
up its feathers to hold in the heat. A walrus keeps warm with the help of a
thick layer of blubber. You and I need to put on warm layers of clothes to
stay warm outdoors - either that or we come inside!
THIS WAS THE QUESTION...
Your body makes its own heat. But you feel cold when heat moves away from
you. Fur, feathers, blubber and clothes are all called insulators because
they block the escape of body heat. Can you think of other insulators?
We asked you to try an experiment. You can't see heat move (it's invisible!)
but you can feel the difference that an insulator makes in stopping your
body's heat loss. Put a thick wool glove or sock on one hand. Leave the
other hand bare. Then, hold an ice cube in your hand and count to 20. What
happened? Which hand felt warmer? Which ice cube melted faster? What did you
think would happen if you put a thin stocking on your hand instead of a
thick glove?
HERE ARE SOME OF YOUR RESPONSES:
When i put the sock on my right hand. my hand was warmer. when i put
the ice in both of my hands, my right hand stayed wamer than my left
hand. the ice melted quicker in my left hand than in my right.

We didn't see anything. We felt the air on our hands. The one with the sock
on our hands felt warmer than the bare hand. The sock was trapping the
heat, and thats why it felt warmer than the bare hand.

I put the glove on and I took the two pieces of ice. Then I held them
and counted to 20. The hand with the glove on didn't get as cold as the
other one. The ice cube that I was holding in the hand that had the
glove on it didn't melt as fast as the one that did not have the glove
on it. The heat is coming from my hands!

The first time, the hand with the thick sock was not cold and with the thin
sock, both hands were cold. The heat was coming from our body which made the ice cube melt faster

An igloo made of thick blocks of snow & ice makes a good insulator.
Fiberglass, wood, and stone are good insulators. The hand with the glove will
not feel the cold & will get warmer because my bodyheat is trapped inside. The hand without the glove will get cold because the is no insulation between my hand and the ice cube.

Styrofoam and fiberglass are used to insulate houses. My house has
fiberglass in it. Blankets insulate people when they are sleeping. Carpet
is so fluffy it insulates. Snow is another insulator. Some people put snow
against their house to keep it warmer. Dirt is a good insulator for
creatures' homes because it will keep them warm.

An insulator is something that keeps the warmth in your body, a house, ananimal, and many other things! Fiberglass helps keep it warm in your house. Straw helps keep you warm if you go deep in the haystack. Cotton balls have trapped air space so they would be a good insulator. If you glued cotton balls all over your skin, you would feel warm. If you were to go to sleep without a blanket you would feel cold, but if you went to sleep with a
blanket you would feel warm. Also if you put pine needles all over your
friend, in a few minutes, your friend would probably feel warm.

Did you know fiberglass is really good to keep you warm in a house? Straw is another insulator. It can be used to cover plants to keep them from
freezing. Snow insulates the ground. Some people make their house in a
hill because dirt helps insulate. Wood chips are good for covering and
insulating plants. Pine needles also insulate.

Did you know that snow is an insulator? Well you need to know that there are many insulators in this world. When you're in bed at night, you probably don't even think about whether your bedspread or blanket is an insulator. Have you ever looked outside and seen, leaves, wood, dirt, pine needles, and straw? They are all insulators. In your house you have pink or yellow fiberglass, and that's another insulator for you!!

We use insulators to keep us warm. Squirrels sleep in leaves in the
winter. Birds use sticks to build nests. People use styrofoam to insulate
their houses. Straw is an insulator. If you jump into a haystack, it will
warm you up. Dirt can keep animals warm.
Name: Ray

My house has fiberglass in it. Fiberglass is in my mom's truck.
Fiberglass makes people itch. I have a blanket to sleep with. They
insulate by trapping the air in. Carpets are fluffy so they can trap air.
That's why they feel warm.

You can put wood chips around a plant. Fiberglass is very itchy, and it
insulates in your home. Foam is fun to play with, and it is a good
insulator for coolers. Leaves can make homes for animals. Snow is cold,
but it keeps the ground warm. Plastic is used as an insulator around
electrical wires. This keeps the wires from getting hot.

Leaves on the ground can keep plants from freezing during the winter.
Straw is good for birds because it can keep them warm. Fiberglass is used
for insulating lots of things like houses. Styrofoam is used to insulate in
coolers, walls, attics, and basements. Dirt is a good insulator for ants and
worms. Some people put snow against their house because it keeps it warmer. Carpet is an insulator because it keeps the cold out.

Fiberglass is used to insulate houses. Did you know that fiberglass can be
12 inches thick? The thicker it is the warmer it is. Leaves can be
insulators for animals to keep them warm. Leaves can keep seeds from dying. Foam is an insulator that you can also sit on.

Snow holds the ground's heat. Leaves keep new sprouts from freezing in the spring. Also leaves keep rose bushes from freezing. Fiberglass keeps the heat from getting out of your house, and it saves electricity. Dirt keeps
the roots from freezing. Polyester is an insulator inside quilts to keep
you warm at night. Styrofoam is used inside of coolers to keep your stuff cold.

A cardboard box is an insulator for people that don't have homes. Snow is another insulator. Foam is an insulator because it traps air in it. Cotton
is one, too. Fiberglass is glass that is in very little pieces. It works
by trapping air.

People put snow against their houses to keep their house warmer. Also
people use fiberglass in their basements or their attics. I use pine
needles for covering my mom's flowers. When they built my house, they used
styrofoam. My dad uses cardboard in the front car window to keep out the
heat. Sometimes I put wood chips in my fort to keep warm.

Now I am going to tell you some of the insulators we use almost every day.
At night we use a blanket. Here's an insulator that helps everyone. It is
called fiberglass. It helps insulate our house. Some people think straw is
not an insulator, but it is. When a cow is cold, it will lay down in straw
and get warm.

There are lots of different insulators. Fiberglass insulates your home and
is very itchy. Another insulator is paper. When you buy something that is
cold, they put it in a paper bag to keep it cold. Another insulator is
leaves. Leaves keep animals warm. Leaves also keep the ground and plants warm.

WE LEARNED THAT THE GLOVE ACTED AS AN INSULATOR. THE ICE IN THE HAND
WITH THE GLOVE MELTED SLOWER THAN THE ICE IN THE HAND WITHOUT THE
GLOVE. THE HEAT FROM THE LATTER HAND WAS BEING RELEASED WHILE THE HEAT
FROM THE GLOVED HAND WAS BEING TRAPPED. THE GLOVE ACTED AS AN INSULATOR
JUST LIKE ANIMAL'S SKIN AND THE BIRD'S FEATHERS.

Animals use leaves to keep them warm. Squirrels build nests with
leaves. Leaves keep sprouts from dying in the spring. Snow can keep the
ground from freezing. Fiberglass keeps our house from getting cold. The
carpet keeps our feet warm. Styrofoam is used in cups to keep things hot or
cold.

Styrofoam is a good insulator. Some styrofoam is easy to tear apart. You
can paint it any color, if it is white. Styrofoam keeps heat in or out. I
like insulators because they keep you warm. Fiberglass helps keep it warm
in your house.

One insulator is an oven mitt. It blocks the heat by absorbing it into it's
many layers of fabric. Another insulator is copper. Copper blocks electricity
because the electricity can't get through the layers of minerals. Another
insulator is a large, or "winter"
coat. It stops the heat from your body from escaping.

1. The ice melts very fast when it hasn't any coldness.
2. The ice is a big chunck of frozen water.
3. When ice is in a hot tempature it melts very very fast, and then it
turns into water.
4. Ice is a cold frozen liquid.
5. The gloved hand that had ice in it, didn't melt as fast as the other.

Another insulator is plastic wrap. It will trap in heat from your body and
keep rain or snow off of your body. We can recycle the plastic {which will
make the world a better place} to make plastic wrap.
