!
!
How does buttermilk curdle milk? The bacteria in buttermilk produce enzymes that cause curdling.
Describe two methods to make cheese. How are they similar?
!
Define the manipulated variable and the responding variables in this experiment.
!
What are the many factors that must be controlled in this experiment?
!
Why did we test milk as a curdling agent?
!
!
How does use of whey-o-meter affect results if a large quantity of whey is trapped in the meter?
!
Does this give the impression that more cheese is made or less?
!
How could the design of this experiment be improved?
!
What is biotech?
Describe two mainstream products of the biotech industry. How are they produced?
What are the four domains that biotechnology products are categorized into?
Compare & contrast government funded vs. privately funded research in the biotechnology sector.
!
Where is the research done? Where does the money come from? What is the purpose of the !
!
!
research? To whom must they report the findings?
Describe & use the scientific method!
hypothesis- is a testable proposal that explains or predicts an event
!
!
- is often in the form, “If the manipulated variable is changed like this, then the
!
!
!
responding variable should behave in this way.”
manipulated variable (independent variable)- is purposefully varied or changed in the experiment.
!
!
!
!
!
!
!
- is graphed on the x axis (horizontal axis)
!
responding variable (dependent variable)- is measured in the experiment
!
!
!
!
!
!
!
- is graphed on the y axis (vertical axis)
!
controlled variable- Describe conditions that must be controlled for reliable results.
!
Why must results of experiments be shared within the scientific community (peer-reviewed) in
!
!
order to be validated?
!
Why must experiments be reproducible in order to be validated?
!
What role does statistical analysis play in scientific experimentation? Statistical analysis allows us to
!
!
!
!
determine appropriate sample sizes and number of repeated trials. Statistical analysis is used to determine if
experimental results are significant or possibly due to random variations.
Human Genome project implications!
What do we know about the human genome as a result of this project? What are the social and
!
!
medical implications of this knowledge?
!
!
What role did collaboration (working together) and communication (sharing information) play in
!
completing this project? Over 200 government funded labs in the USA, with more in the private sector
!
!
!
What do we still need to understand concerning the human genome?
!
and other nations were working together to produce the final product.
Research & development by biotech companies (issue of regaining cost)
Describe some scenarios that may end the development of a biotechnology product.
What entities exist to regulate products, including biotechnology products, in the USA? What role do they
!
play?
Purpose for legal, scientific notebook- including signatures, witnessing, format for corrections,
!
observations, materials and procedure
Formulate REE, PE, & PA conclusions
Biotechnology is one of the fastest growing industries in the USA and the world. The long term outlook
!
for this sector is very good.
What types of employment are available? What levels of education are required? What are the non!
scientific jobs that the biotech industry generates?
What majors should a future biotechnologist consider?
How do computer scientists and engineers contribute to the biotechnology industry?

cons for the issue.)
