 ===Meaning===
 To '''observe''' is to collect and record information during an [[Experiment|experiment]] using scientific tools and [[Measuring Instrument|instruments]] ideally in a way that does not affect the [[experiment]]. In some [[Experiment|experiments]] observing is not a passive activity and the act of observing changes the [[results]] of the [[experiment]].
