===About Observing===
: We might [[Sight|watch]] and [[Hearing|listen]] and if it is safe then we might [[smell]] or even [[touch]] something to '''observe''' it.
: We might also use a [[ruler]] to [[measure]] the [[length]] of something or a [[timerstopwatch]] to [[measure]] how long it takes for something to happen.
===Examples===
: A [[scientist]] uses a [[Stopwatch|timerstopwatch]] to see how long it takes for a [[kettle]] to [[Boiling|boil]].
: A [[scientist]] took one picture of a [[plant]] every day to see how it [[Growth|grows]].
: A [[scientist]] [[Touch|touched]] a [[window]], a [[brick]] and some [[carpet]] to find out which one had the roughest [[texture]].
===Used in a Sentence===
: A [[scientist]] to '''observes''' how long it takes a [[kettle]] to [[Boiling|boil]] one cup of [[water]].
: A [[scientist]] '''observed''' the [[growth]] of a [[plant]] by taking a picture every day.
: A [[scientist]] wrote down '''observations''' of the [[texture]] of different [[Surface|surfaces]].

===About Observations===
: '''Observations''' may be informal (not part of an [[experiment]]) and can be used to make a [[hypothesis]] which then leads to an [[experiment]].
: Some '''observations''' are made during an [[experiment]] because the [[Dependent Variable|dependent variable]] cannot be [[measure]]d. This might happen if there is a colour change of an [[Indicator (Chemistry)|indicator]] or a [[precipitate]] is formed. In both cases these are not [[measure]]d but [[observe]]d.
==Key Stage 4==
===Meaning===
To '''observe''' is to collect and record information during an [[Experiment|experiment]] using [[Scientific|scientific]] tools and [[Scientific Measuring Instrument|instruments]]. Any [[data]] collected during an [[experiment]] is called an '[[Observation|observation]]'. ===About Observations===: '''Observations''' may be informal (not part of an [[experiment]]) and can be used to make a [[hypothesis]] which then leads to an [[experiment]].: Some '''observations''' are made during an [[experiment]] because the [[Dependent Variable|dependent variable]] cannot be [[measure]]d.

==Key Stage 5==
===Meaning===To '''observe''' is to collect and record information during an [[Experiment|experiment]] using [[Scientific|scientific]] tools and [[Scientific 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]].
