Answer:
Scientists develop knowledge by making <u>observation</u> about the natural world that may lead to a scientific question.
A scientific question may lead to a(n) <u>hypothesis</u> which can be tested.
The results of <u>experimentation</u> can lead to changes in scientific knowledge.
Explanation:
In the process of developing scientific knowledge, scientists carry out series of observations on what happens in the natural world. This helps them to develop scientific questions. These scientific questions drawn can then lead to hypotheses which are testable.
The testing process leads to experimentation. It is in this process that much scientific questions receive answers. Testing actually lies at the core of scientific inquiry for all scientists. Whatever hypothesis made must always be tested.
The result of the testing or experimentation brings changes in scientific knowledge.
