3. Purpose
To find out what materials are the best insulation.
Keeping the heat in and the cold out.

4. Materials
• A woolen sock
• A plastic bag
• A piece of newspaper
• A piece of tinfoil
• Four Plastic bottles
• A thermometer
• Hot water
• Tape
• A rubber band

5. Hypothesis
I think the woolen sock will be the best
insulator, because woolen socks keep my
feet really warm when I am out in sub
zero temperatures.

6. Procedure
1. Pour an equal amount of hot water into each of the four
bottles.
2. Put the caps on all of the bottles.
3. Wrap one bottle in tinfoil then tape it so it will stay in
place.
4. Wrap the second in newspaper and tape it again.
5. Wrap the third in a plastic bag and put a rubber band over
it.
6. Pull a woolen sock over the fourth.

7. Procedure (continued)
7. Take the caps off to take the temperature of each of
the bottles. Make sure they are all about same
temperature; if they differ by three degrees or
more, fix it by adding hot/cold water.
8. Take the temperature again in five minutes.
9. Take it again in ten minutes.
10. Take it for the last time in twenty minutes.
11. Record the information.

Woolen Sock 92:C 83:C 78:C 71:C
Plastic Bag 92:C 86:C 74:C 62:C
Newspaper 92:C 84:C 80:C 69:C

Tinfoil Plastic Bag

10. Conclusion
My hypothesis was correct, the woolen
sock was the best insulation over time. In this
experiment the woolen sock bottle lost 21:C,
the plastic bag bottle lost 30:C, the tinfoil
bottle lost 27:C and the newspaper bottle lost
23:C. So the plastic bag is the worst insulation
over time.

11. Big Idea
To keep things hot for longer, (e.g hands,
feet, etc.) the best material to use would be
wool. To keep things hot for five to ten minutes,
newspaper or plastic bags would be the better
insulation materials.
