Winter Experiments For Kids - A jacket for the home

In winter, cold weather, it pays to wear a heavy coat and wool socks and wear a fur coat.
Does the wool and skin on?

Materials needed for this winter experiment

  • 2 identical ice
  • 4 courses
  • 2 coins
  • 1 pair of wool socks
  • 1 bowl full of water
  • heating operation

Experience

  1. Place the two coins on the heat until heated through.
  2. Locate the four plates on the table and put an ice in the first, second sock in which you’ve slipped the second ice. In the third place a dish of hot split and the last plate the second layer within which currency you have slid the second heat.
  3. Wait 30 minutes and review the status of the ice and the temperature of the coins.
  4. Dip a sock inside the container with water and keep it submerged.

What do you notice?

The explanation of Winter Experiments For Kids
The ice tucked inside the sock wool melted slower than
was out. The coin stuck in the wool was cooled more slowly than was
outdoors. The wool then seems not to heat on one side and keep the heat
other. The submerged wool sock does not sink and small air bubbles
escape. The wool traps the air in its fibers, reduces the heat transfer
and retains heat or cold.
Wool is a thermal insulator. Coats and dresses lessen the passage of heat
the body (37 ° C) to the external environment.

Application
Like wool, polyethylene and cork are
materials that contain air. Can be used
as thermal insulation in homes. We found
panels are made of polyethylene for
double colored walls (in contact with the
external), or plates, particularly when they
separate rooms or barns
basement. In this way reduces the loss
heat.
