Biology is the Biology is the scientificscientific study study of life.of life.
But what does “scientific” mean?Science = Latin meaning “to know”Doing science = finding out about
nature Asking questions Searching for answers
Two Ways to Do ScienceTwo Ways to Do Science
Discovery Science = Describing Nature
Example – Tadpoles change into frogs
Hypothesis-based Science = Explaining Nature
Example – Do frogs like flies better than other insects?
Discovery Scientists Observe Discovery Scientists Observe NatureNatureJane Goodall learned about chimpanzees in

Discovery ScienceDiscovery ScienceMake observations by using your
5 senses:

Explain NatureExplain NatureIt always starts with a problem…
Why isn’t my iPod working?
Hypothesis-Based Scientists Hypothesis-Based Scientists
Explain NatureExplain NatureThen you research what’s wrong…
Hypothesis-Based Scientists Hypothesis-Based Scientists
Explain NatureExplain NatureThen you make a hypothesis…
If I turn it off and then turn it on, maybe it will fix the problem.
Hypothesis-Based Scientists Hypothesis-Based Scientists
Explain NatureExplain NatureThen you experiment on it… TRY IT OUT!
Hypothesis-Based Scientists Hypothesis-Based Scientists
Explain NatureExplain NatureThen you collect data
“Turning it off and on did not fix the problem.”
Hypothesis-Based Scientists Hypothesis-Based Scientists
Explain NatureExplain NatureThen you analyze the data
“Turning it on and off didn’t work, so… I’ll have to try something else!”
