INTERACTIONS
AND INTERDEPENDENCE
Goals: This
unit helps students understand the concept that all living elements of
an ecological system are interdependent. Plants and animals live in a
community in which each species contributes to the functioning of the
overall system. In a functioning ecosystem, life forms and environmental
factors interact to maintain a dynamic equilibrium.
Objectives: By completing this unit the students will be able to:
- define interdependence,
community, and exotics.
- describe a food
chain and extend it to a food web.
- evaluate how a
complex food web will adapt to change compared to a simple food chain.
- identify ways
that humans have changed or could change a food web (pollution, introducing
exotic, causing extinctions) and speculate how that change will affect
the members of the food web.
- select an animal
of their choice and find examples of how other plants or animals are
dependent upon it. Name plants or animals that are dependent upon the
animal. Add humans to the list and compare their needs, explaining how
they are dependent upon plants and animals.
- discuss the relationship
and responsibilities humans have to our planet.
- recognize interrelationships
among living and nonliving elements of the environment.
- list two things
the cave is dependent upon and describe the importance of these connections.
- evaluate how humans
have changed the ecosystem of the cave and predict the effect it may
have on the future of the cave.
These objectives
will be achieved in three stages:
- Nametags, pre-visit
activities and information - teacher(s) will complete Nametag Activity
and select at least one Pre-visit Activity to do in the classroom before
visiting Wind Cave National Park. Selection of activities will be communicated
to the ranger leading park program.
- Park activities
- ranger directed with assistance and supervision of the teacher and/or
teacher aide.
- Post-visit activities
- teacher(s) will select at least one Post-visit Activity to do in the
classroom after visiting Wind Cave National Park.
