Why is observation and experimentation a good method for making scientific discoveries

Observation is essential in science. Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways - with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing.

The key concept of the scientific method is that scientists can answer questions and test hypotheses, or potential solutions, through highly controlled experiments ... Researchers often investigate several hypothesis simultaneously while conducting elaborate experiments.
