Living Systems and
Environment
|
In the
fourth unit, Living Systems & Environment, the students
will be able to describe interactions between human body
systems.
Students will know that the homeostasis of an
organism depends on all parts of the organism working
together and is also dependent on the environment.
Students will be able to identify how negative and
positive feedback mechanisms aid in homeostasis.
Students will be able to describe how organisms
interact within an ecosystem. Students will know that
environmental changes in Earth's cycles can occur that
will affect homeostasis through natural and human
impact.
Critical Questions
- How do human body systems interact to maintain
homeostasis?
- In what ways do living systems interact?
- What affects do natural and human events have on
the environment and species extinction?
