Unit Plan: The Local State Park

In this high school science lesson, students learn about the ecosystem of a local park. By studying the interrelationships among organisms living within the park, students gain an understanding of the complexity of the ecosystem.

Because the park is also used by people, students will examine how human activities affect the organisms. With this in mind, they will look at how land-use policies are created and what it means to balance the needs of the organisms with the needs of people wanting to use the park.

Essential Questions

  • What is species diversity?
  • How are species interrelated?
  • How do humans affect/interact with other species and the environment?
  • How are public lands utilized?
  • How does public land use affect the local ecosystems?
  • How should public lands be used?
  • How can you affect public policy?

Assessment Strategies

  • Preassessment:  K-N-W-L Sheet and general observation
  • Formative:  Notebook records and observations and class discussions
  • Summative:  Presentations using appropriate rubric

Materials and Resources Needed

  • See lessons plans that follow

Map of the Unit

  • Lesson 1—The Local Forest (1 day)
  • Lesson 2—Interdependence Between and Among Plants And Animals (1 day)
  • Lesson 3—Land Use in a Public Park (1 day)
  • Lesson 4—Ecology of the Park (2 days to 1 week)
  • Lesson 5—Presentation of a Position on the Use of Public Lands (1 week to prepare presentations, as much time as needed to present)

Lesson 1—The Local Forest

Objectives

  • Become familiar with the park through observation, reflection and discussion.
  • Prepare for later activities in this unit, which will require more focused observation.

Activity—Observe the forest

  • Walk through Ridley Creek State Park, observing the forest, the river, the plants, the animals and the human impact.
  • K-W-L-H Record Sheet:  record the following before, during and after the walk.
    • What I know about the forest and its surroundings
    • What I want to know about the forest and its surroundings
    • What I learned (observed) about the forest and its surroundings
    • How I will learn what I want to know about the forest and its surroundings.
    • Students share their findings and observations with the class.

Materials

  • Laboratory notebooks
  • K-W-L-H Record Sheet

Assessment

  • K-W-L-H Sheet
  • Notebook observations
