Q
  • logical and rational order of steps by which scientists come to conclusions about the world around them.
A

Scientific Method

17
Q

define the problem you wish to explain

A

Define

18
Q

one or more falsifiable explanations for the observation.

A

hypothesis

19
Q

Controlled attempts to test one or more hypotheses. This is the part of the scientific method that tests your hypothesis.

A

Experimentation

20
Q

After this step, the hypothesis is either modified or rejected, which causes a repeat of the steps above.

A

Conclusion

21
Q

“an educated guess”

A

Hypothesis

22
Q
  • a widely accepted explanation of natural phenomena;
  • a hypothesis that has been repeatedly tested with little modification
A

Theory

23
Q
  • a statement of what always occurs under certain conditions
  • one of the fundamental underlying principles of how the Universe is organized
A

Law

24
Q
  • Any activity made by living organisms.
A

LIFE

25
Q

CHARACTERISTICS OF LIFE

A
  • Organization
  • Maintenance of internal constancy
  • Irritability and adaptability
  • Energy use and metabolism
  • Reproduction, growth and development
26
Q
  • all form of life formed from a supernatural power called God. Though it is not accepted as it has no scientific evidence.
A

Theory of Special Creation/Divine Creation

27
Q
  • life originated spontaneously from inanimate objects.
A

A

Panspermia

33
Q

a simulation of conditions on the early Earth testing the idea that life, or more specifically organic molecules, could have formed by nothing more than simple chemical reactions.

A

Theory of Chemical Evolution

34
