Observation is the primary tool used for collecting and recording data. Scientists rely on observation to determine the results of theories. Hypotheses are tested against observation using tools or human senses.
Observation has been used by scientists since at least as early as ancient Greece. Observations of earthworms led many philosophers and scientists to learn how to identify and quantify results of scientific studies. This form of inquisition helped lead scientists to be able to test new theories as different methods of observation were developed. New forms of observation occur as technology advances. This broadens the capacity for observation and scientific inquiry.
Observation is not limited to scientists. It is also one of the primary ways in which humans and animals learn how to interact in their respective environments. Observation is when something is noticed and is then recognized as being important. This process helps on basic levels of survival, such as an individual's understanding not to walk out into a busy street without looking for oncoming traffic.
Animals follow similar basic levels of observation. If an animal sees other animals feeding in a specific location, it recognizes the behavior as a clue to a possible meal. Scientists typically rely on instruments to help them create observations on a more objective level.Learn More
Questionnaires are a cost-effective, simple and quick way to gather data that comes straight from the sources. This research method has been used for decades to gather data en masse, but it comes with its own complications and setbacks.Full Answer >
A science project that can involve growing a bean plant is "Observation of changes in a plant as it grows." Plant a bean and care for it as it grows while observing its progress and recording its appearance, measurements and how long it took for each major transformation to occur.Full Answer >
A scientific law is a generalization based on observations of a phenomenon. It gives descriptions regarding an event that occurs repeatedly when certain conditions are met, but it does not explain why the event happens. At the time a law is made, no exceptions currently exist.Full Answer >
A good theory should explain the observations or results of an experiment or phenomena, being understandable to a lay person while also being reasonable enough to allow for further testings. A good theory should also be frugal in their nature so others can test it, and they should also be predictive.Full Answer >
