A hypothesis is a scientist's first, educated guess at the solution of some problem, e.g., why did this chemical reaction occur?, or, why does the Sun do such-and-such? A scientist tests the hypothesis in an attempt to refute it, and the hypothesis that survives all such tests becomes the reigning theory in that branch of science, e.g., relativity theory, plate tectonics, natural selection, etc.

What is the role of falsification in the context of scientific statements?

In order to be able to demonstrate that a statement is true, there has to be some test for it to pass; if it does not pass the test it can be considered false. So, a statement that is testable can also be called falsifiable. That does not mean that it is false, it just means that until you have tested it, there is a theoretical possibility that it will turn out to be false. This is considered to be a necessary part of any scientific hypothesis. If you make a hypothesis which cannot be tested, then it has no scientific use.
