Changes

Investigate the effectiveness of different [[Thermal Insulator|thermal insulators]] on reducing an [[Energy Transfer|energy transfer]] by [[heating]].

: [[Independent Variable]]: [[Thermal Insulator|Insulating material]].

: [[Dependent Variable]]: The [[temperature]] decrease of [[water]] after a given [[time]].

: [[Control Variable]]s: The [[Volume (Space)|volume]] of [[water]] used. The initial [[temperature]] of the [[water]]. The [[time]] taken between [[measurement]]s. Thickness of the [[Thermal Insulator|insulating material]].

#Repeat steps 1-3 with a can covered each type of [[Thermal Insulator|insulating material]].

: Place the cans on a [[Heatproof Mat|heatproof mat]] to reduce the [[Thermal Energy Store|thermal energy]] lost to the table surface by [[Thermal Conduction|conduction]].

: Place a lid over the cans to reduce the [[Thermal Energy Store|thermal energy]] lost to the [[air]] by [[evaporation]].

: Use a [[thermometer]] with a higher [[resolution]].

: Use a [[Data Logger|data logger]] rather than a [[thermometer]].
