For example, anecdotal evidence from a friend about how to treat a certain disease constitutes empirical evidence that this treatment works but would not be considered scientific evidence.

A theory is a carefully thought-out explanation for observations of the natural world that has been constructed using the scientific method, and which brings together many facts and hypotheses.

the system of rules which a particular country or community recognizes as regulating the actions of its members and which it may enforce by the imposition of penalties.

An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried.

a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.

A dependent variable is what you measure in the experiment and what is affected during the experiment.

Observation is a method in which a person observes behaviour to note changes in people or places, typically as the result of an intervention.

An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure.

facts and statistics collected together for reference or analysis.

someone or something set before one for guidance or imitation.

Engineering is a field and profession that focuses on the development of technology for the advancement of our civilization.

Technology is the use of scientific knowledge for practical purposes, and for solving problems.

an original model on which something is patterned

A trade-off refers to a decision where you must give up, or sacrifice, one thing in order to achieve another.
