What makes good science?
What is Science?
Science is concerned with understanding how nature and the physical world work.
Science is a process by which we try to understand how the natural and physical world works and how it came to be that way.
Science can prove anything, solve any problem or answer any question.
Any study done carefully and based on observation is scientific.
Objective= Not influenced by feelings, interests and prejudices; UNBIASED
Subjective = Influenced by feelings, interests and prejudices; BIASED
Science can be done poorly.
Anything done scientifically can be relied upon to be accurate and reliable.
Different scientists may get different solutions to the same problem.
Knowledge of what science is, what it can and cannot do, and how it works, is important for all people.
What is good science?
Objectivity is the key to good science.
To be objective, experiments need to be designed and conducted in a way that does not introduce bias into the study.
Be careful not to confuse an observation with an inference
HYPOTHESIS—proposed, testable explanation for the way “something” functions. The “educated guess”

Good science depends on a well-designed experiment that minimizes bias by using the appropriate:
All organizations produce unbiased data. However, it is important to understand the organization’s motivation to be able to identify potential bias. In some situations, the need to promote special interests or make profits may lead to bias.
