PurposeThe purpose of this experiment is to see whichmaterial is the warmest and which material is leastwarm. And which gives the best insolation. And whichmaterial can keep the heat in the bottle the longest.
HypothesisI think the silver foil will maintain the heat for the longest. Becauseit is a metallic material. And I always see my helper using silver foilto cover up the hot food. The heat evaporates and the silver foil willkeep the heat. Last, I think the newspaper because it is quite thin.
Materials I used 4 glass bottles A piece of aluminum foil A piece of plastic wrapping paper One newspaper One woolen sock One digital thermometer A measuring cup
ProcedureStep 1: Place all items in ‘’Materials I used’’ on a table.Step 2:Wrap the silver foil, plastic wrapping paper,newspaper , woolen sock on each identical glassbottles.As you can see in the picture, I alreadywrapped all the materials aroundthe bottles.
ProcedureStep 3:Pour 200 ml of hot water in the measuring cup,then pour all of it in the glass wrapped by silver foil.Step 4: Dip the tip of the thermometer in the cupimmediately then write down the temperature. Repeatstep 3 and step 4 for the other glasses. Record eachtemperature.
ProcedureStep 5:Record the all temperatures again after 5minutes.Step 6: Record all temperatures again after 10 minutesStep 7:Record all temperatures again after 20 minutesStep 8: Note down all temperatures notes and thendraw a chart to compare the temperatures.

ConclusionsIn the experiment, by looking at this chart I found outthat my hypothesis was wrong. Woolen sock was thebest insulator not the silver foil. I didn’t think woolwould keep the heat the longest because it has holes.And what astonished me that was last was the silverfoil.
Big IdeaI have learned that different materials hold heat at adifferent amount of time. I have also learned that youmust use the right material for a certain heat, hot orcold.
