==Key Stage 1=====Meaning===

==ExamplesKey Stage 2==: A ===Meaning===To '''observe''' is to use our [[scientist]] watched an [[insectSense|senses]] to study something very carefully and saw it had 6 [[Leg|legs]].: A [[scientist]] listened or use a tool to the [[sound]] that a [[cat]] makes.: A [[scientist]] looked at lots of [[Flower|flowers]] and wrote down the different [[Colour|coloursmeasure]]something.

==Used in a Sentence==: A '''[[scientistVerb]] wants to ''': To observe how long it takes for an [[apple]] to [[rot]].: A [[scientist]] observed that '''[[The MoonNoun]] is not always in the [[sky]] at [[night]].''': A [[scientist]] made an observation of the colour of different [[Leaf|leaves]].Observation

=Key Stage 2==About Observing===To '''observe''' is to use our senses to study something very carefully. : 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 even a [[stopwatch]] to [[tastemeasure]] how long it takes for something to observe somethinghappen.

===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]].

=Key Stage 3==Used in a Sentence===To : A [[scientist]] to '''observeobserves''' is how long it takes a kettle to collect information during an experiment using our [[SenseBoiling|sensesboil]] one cup of [[water]].: A [[scientist]] '''observed''' the [[growth]] of a [[plant]] by taking a picture every day.: A [[scientist]] and wrote down '''observations''' of the [[Measure|measuring toolstexture]] and record that informationof different surfaces.

==Key Stage 3=====Meaning===To '''observe''' is to collect information during an [[experiment]] using our [[Sense|senses]] and [[Measure|measuring tools]] and record that information. ===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. 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 5=====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]].
