===About Hypotheses===
: A [[hypothesis]] is made after an [[observation]]. The [[hypothesis]] is an attempt to [[explain]] what has been [[observed]] or [[describe]] a set of rules that the [[observation]] follows(eg the bigger an object is, the heavier it is).: A [[hypothesis]] is used to design an [[experiment]]. A good [[experiment]] is designed to find a way to prove the [[hypothesis]] is wrong. That way it can reduce the effects of [[bias]]. If you set out to prove a [[hypothesis]] is correct it is too easy to cheat. If your [[hypothesis]] was that you're the tallest person in school it would be easy to walk into a classroom full of younger children and say "after testing 25 people I was the tallest". However, if you tried to prove yourself wrong you would walk into a classroom full of the oldest students in school. That way, if you were the tallest in that group, it would be more likely to be true that you are the tallest in school. ==Key Stage 4=====Meaning===A [[hypothesis]] is an attempt to [[describe]] or [[explain]] something before an [[experiment]] has been performed. ===About Hypotheses===: A [[hypothesis]] is made after an [[observation]].
