The document describes an experiment to test which materials make the best insulation. The materials tested were a woolen sock, plastic bag, newspaper, and tinfoil. Hot water was poured into bottles wrapped with each material and temperatures were taken at 5, 10, and 20 minute intervals. The woolen sock proved to be the best insulator, losing the least amount of heat over time, followed by newspaper, tinfoil, and plastic bag. The conclusion is that wool is the best material for long-term insulation while newspaper or plastic bags work better for shorter periods of 5-10 minutes.

Purpose To find out what materials are the best insulation. Keeping the heat in and the cold out.
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
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.
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. Continues on the next page >>>
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.

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.
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.
Thank You
