Chemistry is the science of the matter that makes up our physical world. As a branch of science chemistry enables us to understand all forms of matter. Chemistry is concerned with; properties, composition, behavior and structure of matter, and the changes it undergoes during chemical reaction.
Using concepts, principles and skills in chemistry, we can tap into the things that surround and affect us. Through experimenting we can study chemical outcomes of our surrounding physical composition.
An experiment or test can be carried out using the scientific method to answer a question or investigate a problem. A good experiment usually tests a hypothesis. However, an experiment may also test a question or test previous results.
It is important to take into account all factors in an experiment, as it is also important that the results are as accurate as possible. If an experiment is carefully conducted, the results usually either support or disprove the hypothesis.
An experiment can never "prove" a hypothesis, it can only add support.
