New page

==Key Stage 2==
===Meaning===
An '''experiment''' is when you test a question you have asked by changing one [[variable]] to see how it affects another.
===About Experiments===
: '''Experiments''' are usually done in a '''laboratory''' but they can be done outside.
: An '''experiment''' must be designed well to answer a question. You cannot trust the answer if the '''experiment''' was badly designed. For example you cannot find out who is the fastest in class if you make some people wear their school bags in the race.
