The Scientific MethodRefresh from last time: What is science?
Summarize: _____________________________________________________________
________________________________________________________________________ What are some “types” of science?
____________________________________________________________________________________________________________________ What is biology?
_________________________________________________________How does science work? Use of the scientific method…• In reality, there isn’t a single method, but this is a general overview• Use the graphic on the back of this page to follow along
Let’s apply this to a real world problem...• Clostridium Difficile is a very uncomfortable disease that can be
_________ _________ with __________________.What is a way we can state the problem described? • Treating a Clostridium Difficile infection with antibiotics can worsen
the disease and an alternative treatment is necessary.• How can we make this statement better?

Why is doing background research so important?• Notes from discussion: _______________________________________________________________________________________________________________________
A good hypothesis is:– Simple and clear– Written as a statement, often as an “If…., then….” statement– Establishes variables– Predicts an outcome– Is testable
Hypothesis: ______ C. difficile causes symptoms when it replaces normal gut flora, ______ reintroducing healthy gut flora, through a ______ ____________, will eliminate the C. difficile infection.Test your hypothesis by designing an experiment• Describe an experiment to test this hypothesis and include the types
of materials you would use. _______________________________________________________________________
The Scientific Method______________________________________________________________________________________________________________________________________________Analyze the Data
What trend did you notice from the data? __________________________________
__________________________________________________________________________Draw Conclusions• Did the fecal matter transplants seem to work?
______________________________• Do you think a single experiment is enough?
______________________________• The importance of RETESTING
Now You Try!• What is the problem the doctor is trying to solve?____________________________________________________________________________________________________________________________________________________• What is the doctor’s hypothesis?____________________________________________________________________________________________________________________________________________________• What was the first experiment he did?____________________________________________________________________________________________________________________________________________________• Did his first results support his hypothesis?____________________________________________________________________________________________________________________________________________________
