Critical Thinking
- Evaluating an ArgumentA scientist on
television states that a hypothesis cannot be
proven. Do you agree, or do you disagree?
Explain your answer. - Forming Reasoned OpinionsSome people
believe that scientists should not tamper
with a person’s genes. Do you think biolo-
gists should use gene therapy to try to cure
diseases? Explain your answer. - Applying Information One of the most
important parts of any scientific publica-
tion is the section that describes methods
and materials used. Why might such details
be so important? - Applying Information One of the first
branches of biology to be developed was
taxonomy, the naming and grouping of
organisms. Why is taxonomy important to
communication about biology?
Alternative Assessment
- Finding InformationUse the media center
or Internet resources to explore community
gardens. Prepare an oral report that
describes the mission of the American
Community Gardening Association and
how community gardening works to ease
the stress on the environment. - Career FocusEnvironmental Biologist
Research the field of environmental biology,
and write a report on your findings. Your
report should include a job description,
training required, kinds of employers,
growth prospects, and starting salary. - Interactive Tutor Unit 5HeredityWrite a
report summarizing how an understanding
of heredity allows animal breeders to
develop animals that have desirable traits.
Find out what kinds of animals are bred for
special purposes.
