To '''observe''' is to use our [[Sense|senses]] to study something very carefully or use a tool to measure something. 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 [[timer]] to [[measure]] how long it takes for something to happen.
