===About Fair Tests===
There are many ways to make a test unfair.
: If we wanted to see who is the fastest in class we would do a '''fair test ''' where we would make sure everyone is wearing shoes, no-one is wearing their school bag and everyone has to run the same distant. The test would not be fair if some people weren't allowed to wear shoes, or some had to wear their school bags.: If we wanted to whether know which dissolves best sand, salt, flour or sugar dissolve in a '''fair test''' we would make sure we used the same amount of water, the same amount of each powder and stir them for the same amount of time. The test would not be fair if we used different amounts of water each time, or a different amount of powder or didn't stir some of them.
: In a '''fair test''' you can trust the results. If an [[experiment]] is not a '''fair test''' then you cannot believe your results because they may be caused by you changing something else.
==Key Stage 3==
===Meaning===
A '''fair test''' is an [[experiment]] in which only one [[variable]], the [[Independent Variable|independent variable]], is changed to make sure [[result]]s are only affected by the [[Independent Variable|independent variable]].
===About Fair Tests===
: An [[experiment]] can be made a '''fair test''' with [[Control Variable]]s. If there are enough [[Control Variable]]s then only the [[Independent Variable|independent variable]] will be able to affect the [[Dependent Variable|dependent variable]].
