A hypothesis is a guess as to why something happens.
Observations lead to questions regarding the event.
If you have ever made a guess about how something works, you have made a hypothesis . If you then try to answer your own question by observing or thinking about it, you've come up with a hypothesis. Scientists make hypotheses all the time. That is how scientists can come up with new medicines and products, and how they think up ideas how to use things we already have in different ways. Inc.
