List 3 ways to be principled in science.
Not ignoring data – Always record and report all results, even if they don’t fit the hypothesis.
Minimizing harm – Make sure experiments do not harm the environment, humans, or animals.
Respecting participants’ rights – Treat all participants ethically and fairly.
Limiting bias – Design experiments so personal opinions or preferences do not influence results.
Being honest – Report methods, data, and results truthfully.
Following safety rules – Conduct experiments safely to protect yourself and others.
