Science/Strand III/Content Standard 3/Middle School/Benchmark 2
Benchmark Question: In what ways do living things adapt
to survive in their environments?
Focus Question: How do inherited traits allow
organisms to become better adapted to their environments?
The teacher will ask the
class to consider the following general questions:
1. What changes can take place in an island ecosystem?
2. How might these changes affect the process of natural
3. Which inherited traits might be passed on from
generation to generation?
4. Looking ahead, what other events may cause an
organism to adapt over time?
The teacher will present the
students with the following scenario:
Pretend that you are a
scientist in the year 2020. You observe that a longer grass has invaded an
island. How might a ladybug population living on this island adapt to this
change in environment? Consider the following traits: body color,
exoskeleton hardness, size of wings, length of legs, etc.
In small groups, students
will write predictions about the adaptations they think might occur in
order for the ladybug population to survive. Each student will justify his
or her predictions and present his or her reasons in chart form. Use a
chart with the headings: ADAPTATION, REASON.
