===About Scientific Enquiries===

: '''Scientific enquiries''' must follow the [[Scientific Method|scientific method]] which means they must [[Test (Science)|test]] a question and make sure it is not influenced by a person's beliefs. When a person's beliefs change the outcome of an [[experiment]] this is called [[bias]].

*[[Valid]] - The [[experiment]] you perform must be related to the question you are testing. If you want to know the tallest person in school you can't find out by measuring the size of everyone's hands.

*[[Objective]] - It shouldn't matter who does the experiment, everyone should get the same [[result]]s.

*[[Repeatable]] - Doing the same [[experiment]] over and over should always give the same [[result]]s.

*A [[Fair Test]] - Only one [[variable]] should be changed in an [[experiment]]. Finding out whether mustard or cress grows faster would not be a [[Fair Test|fair test]] if the mustard was next to the window, but the cress was in a dark cupboard.
