Improving Precision
====Improving [[Accuracy]]====
: Place the [[Electronic Balance|electronic balance]] on a flat, level surface to get an [[accurate]] reading of the [[mass]].
 
====Improving [[Precision]]====
: Use a larger cuboid to reduce the [[uncertainty]] caused by the [[resolution]] of the [[Electronic Balance|electronic balance]] or [[Measuring Scale|measuring scale]].
===Experiment 1: Irregular Solid===
: Place the [[Electronic Balance|electronic balance]] on a flat, level surface to get an [[accurate]] reading of the [[mass]].
: Place the [[Measuring Cylinder|measuring cylinder]] on a flat, level surface and read it from eye level to get an [[accurate]] reading of the [[Volume (Space)|volume]] of [[water]].
: Ensure no [[water]] is spilled to get an accurate measurement for the [[Volume (Space)|volume]] of the [[object]].
: Ensure the [[object]] is fully submerged to get the correct value for the [[Volume (Space)|volume]] of the [[object]].
====Improving [[Precision]]====
: Use a larger Ensure no [[objectwater]] to reduce is spilled from the [[uncertaintyMeasuring Cylinder|measuring cylinder]] caused by so that all repeat readings are the same.: Measure the 'dry' [[resolutionmass]] of the [[Measuring Cylinder|measuring cylinderobject]] to ensure repeat readings are not affected by [[water]] permeating the [[object]].
