===Meaning===
Investigate the effectiveness of different [[Thermal Insulator|thermal insulators]] on reducing an [[Energy Transfer|energy transfer]] by [[heating]].
: Place a lid over the cans to reduce the [[Thermal Energy Store|thermal energy]] lost to the [[air]] by [[evaporation]].
: Complete the experiments with different [[Thermal Insulator|insulators]] simultaneously so that a change in the [[temperature]] of the [[laboratory]] does not affect the [[results]].
: Place the [[Measuring Cylinder|measuring cylinder]] on a flat, level surface and read it from [[Eye Level|eye level]] to get an [[accurate]] reading of the [[Volume (Space)|volume]] of [[water]].

====Improving [[Precision]]====
: Use a Ensure the same amount of water ([[thermometerControl Variable]] with a higher ) is used in each container to reduce the [[resolution]].: Use a [[Data LoggerRandom Error|data logger]] rather than a [[thermometerrandom error]]in repeat readings.
