Scientific Processes

1. Asking a question John Endler Univ of Cal - why is there a

significant difference in populations of guppies

regarding average age and size @ sexual

maturity?

Scientific Processes

2. Hypothesis -

testable, tentative explanation

for what we observe.

Could it be the

predator which preys

predominately on the

population?

Scientific Processes

3. Prediction - if/then (If the hypothesis is true, then the results of the experiment will be…)

IF, guppies from Pike-

Cichlid pools are

introduced to new pools

th,at contain only

killifish THEN, the

average age and size at

maturity will be

heavierand older than

nontransplanted

individuals

Scientific Processes4. Testing the validity of the hypothesis

Control Group - the group not moved

Experimental Group - the group that was moved to the pool with only killifish, and no guppies

Scientific Processes5. Conclusion
