==Key Stage 3=====Meaning===To '''measure''' is to use a [[Scientific Instrument|scientific instrument]] to find the size or amount of something. ===About Measuring===:When you '''measure''' something you have to be careful to use your [[Scientific Instrument|scientific instrument]] carefully to get the right measurement.: You must use the right tool for the job. You must use a [[ruler]] to '''measure''' height, a [[timer]] to '''measure''' time and a [[thermometer]] to '''measure''' [[temperature]]. ==Key Stage 4=====Meaning===To '''measure''' is to take two [[reading]]s from a [[Scientific Instrument|scientific instrument]] and find the difference between them. ===About Measuring===: To [[measure]] something the value and the start and the value at the end must be [[reading|read]] and then subtracted from one another.: A '''measurement''' is the difference between two [[reading]]s. ===Examples===: The length of an [[object]] can be [[measurement|measured]] by using a [[ruler]] to take a [[reading]] at both ends of the [[object]] (eg 5.3cm and 7.6cm [[reading]]s gives a [[measurement]] of 2.3cm long).
