Impacting Ecological Stability through Sustainability

Grade 5, Interdisciplinary

Description of Unit

This task designed for fifth-grade students will explore conservational, environmental, and economic sustainability from multiple perspectives and the change over time in relation to invasive species, human interactions, and on the ecological balance within ecosystems. Moreover, students will research exotic and invasive species in Texas and their own communities. As they conduct this research, students will have an opportunity to report sightings of invasive species to the Early Detection & Distribution Mapping System and even become Junior Park Rangers for the Texas Parks and Wildlife. Product options for this task include the following:

  •  Create a wanted poster that depicts the invasive species and why there is a “price on its head.” The poster should include characteristics, last known location, “crime,” award, suspected sightings, etc.
  • Create and produce a documentary depicting an affected ecosystem through an invasive species or human interaction.
  • Create an original work of art that depicts an ecosystem affected by an invasive species or damaged through human interaction AND shows how the ecosystem could look through restorative actions, preservation, etc.
  • Create a mock trial in which the invasive species is the defendant and the ecosystem is the plaintiff. The students will create a script that includes the “crimes,” evidence, attorneys’ dialogues, objections, verdict, etc.
  • Create a community awareness program with the purpose of teaching the community the importance of protecting ecosystems.
  • Create an informative Prezi, Smore, Weebly, or Symbaloo that reflects the research and learning. Follow all district policies and procedures prior to student usage of technology.

This guide links the Impacting Ecological Stability through Sustainability unit to the Texas Essential Knowledge and Skills (TEKS) for fifth graders. Impacting Ecological Stability through Sustainability is an interdisciplinary unit with connections to math, English language arts, social studies, and science disciplines. For example, students will write expository or informational texts—as outlined in the English Language Arts and Reading TEKS—and understand that there are relationships, systems, and cycles within environments, as described in the Science TEKS. The following document includes the applicable TEKS and the details of the Impacting Ecological Stability through Sustainability unit. The final section of this document presents the applicable Texas College and Career Readiness Standards adopted by the Texas Higher Education Coordinating Board (THECB) on January 24, 2008.

Phase I. Learning Experiences

  1. Students should be thinking like an expert regarding organisms and environments. In addition to defining words or creating graphic organizers, what would happen if we asked students the following: “What specialized language is needed to define and/or describe a producer? How would an ecologist describe the introduction of a non-native species or an ‘exotic’ into a fragile ecosystem?”

    We want students to move beyond the mere knowledge that this would be detrimental to the biodiversity of the region. By continuously immersing students in the language of the discipline and stressing relevancy and vital communication skills, students gradually become users of diverse language skills and extensive vocabulary. Instead of, “Wow, putting non-native plants and animals in the wrong place is bad,” how about, “Invasive species can have varied effects on native species, the surrounding ecosystem, and the economy.”

    Continue to think about the ecosystem scenario. How might an economist respond to the same scenario? If the introduction of a non-native species altered the economic stability of an area, how would an economist discuss the situation? How might a politician discuss the scenario if she or he used it as a platform during an election campaign? As we delve into more depth and move beyond mere rote recall of a definition, we establish higher levels of language development and usage in all students. Language of the discipline is not a list of vocabulary words to memorize. It is an immersion in language associated with myriad aspects of a topic, a discipline, specific content, situation, etc.

  2. Prior to beginning this Texas Performance Standards Project task, set up an Interest Center in your classroom. An Interest Center contains articles, books, videos, activities, learning opportunities, and games associated with the forthcoming learning or topic. As students have time, they will explore the Interest Center to begin the immersion process and create interest in the upcoming unit or topic of study. In addition, students will begin asking questions regarding the topic that they would like to explore further. These questions then become part of the learning.
  3. Divide the class into small groups, with four students in each group. Provide each group with the cards from Attachment #1. The cards need to be printed on cardstock and cut apart for each group.

    Once the cards have been distributed, the groups will look for similarities, familiarities, prior understandings, etc., and categorize the words based on their analysis. Once the words have been categorized, the groups will then create a title for each of the categories. The groups must be able to explain and defend the categorizations and titles.

    Then, using available technologies, the groups will view both of the following videos. During the viewings, the students will have the opportunity to pause and/or rewind the video as they hear information and take notes related to the categorized words.

    The groups will then re-categorize and create alternate titles as appropriate based on the new information gleaned through the self-directed learning.

    Groups will then choose one of their categories and create a pictorial representation (without using words or numbers) that demonstrates the Big Idea of the category.

  4. Display the term, “Invasive Species.” Allow the students time to discuss the term and synthesize a possible definition. Then, using available technologies, students will go to the Texas Parks & Wildlife website regarding Exotic and Invasive Species. http://www.tpwd.texas.gov/huntwild/wild/species/exotic

    Allow time for students to explore the site and accompanying links as appropriate. Then, working in pairs, the students will create a GPS Tour—Guided Professional Sightseeing. As they view the information on the site and the links as appropriate, they will record information they find in a field journal using the following headings:

    • Points of Interest
    • Fascinating Facts
    • Off-the-Beaten Path
    • Sites You Don’t Want to Miss
    • Your Favorite Moments
    These entries are reflections of what the students have learned and find interesting. The field journal entries can then be shared with other groups.
  5. As resources allow, encourage students to become a Junior Ranger through the Texas Parks and Wildlife website: http://tpwd.texas.gov/spdest/programs/jr_ranger/. Moreover, arrange a trip to a State Park near you for a nature field trip. An Activity Journal (http://tpwd.texas.gov/publications/pwdpubs/media/pwd_bk_p4000_2028.pdf) is available for the students to use. In addition, the students should also look for any invasive or non-native species that are in the Park. Prior research regarding the types of invasive species in Texas should be conducted prior to the nature field trip.
  6. Students will also begin recording invasive species in their local communities, county, etc. The Early Detection & Distribution Mapping System is another activity that the students, as a whole or individually, could participate in as reporters of sightings of invasive species. http://www.eddmaps.org/ and http://www.eddmaps.org/texas/.

Phase II. Independent Research

A. Research process

  1. Selecting a topic. Students will select at least one invasive species affecting Texas and investigate how the species was introduced, the short- and long-term consequences to specific types of ecosystems, and current procedures that are being implemented to prevent the spread of the invasive species, and propose a solution to removing the invasive species or protecting the ecosystem.
  2. Asking guiding questions.
    • What are the invasive species found in my community, county, and state?
    • How are the invasive species affecting local ecosystems?
    • How is the ecosystem adapting to the invasive species?
    • What programs are already in place to remove the invasive species or to protect the ecosystem?
    • If the invasive species are not eradicated, will they spread to other ecosystems?
    • What factors contributed to the introduction of the invasive species into the ecosystem?
    • How have the patterns of the indigenous species been altered by the introduction of invasive species?
    • What commonalities are present regarding invasive species in East Texas compared to invasive species in other regions of Texas?
    • Over time, how will the invasive species affect the ecosystem if they are not removed?
    • What economic factors must be considered when planning the restoration of a damaged ecosystem?
    • Do invasive species cause extinction?
    • What additional factors are harmful to ecosystems?
    • How does industrial development affect ecosystems during and after development?
    • Instead of destroying an ecosystem for industrial development, could ecotourism be implemented?
    Throughout Phase II of this task, the students should be asking questions and recording their ponderings in their field journals. While the guiding questions are provided for examples, the questions developed by the students may be more reflective of their interests and lead to more substantive research.
  3. Creating a research proposal. The students’ interests and the guiding questions most relevant to the chosen topic will guide the research proposal. Attachment #2 may be used as a guide to assist students in creating their research proposals.

B. The product

Each student or groups of students may choose from one or more of the following products or propose an alternate product or performance, pending teacher approval.

  1. Create a wanted poster that depicts the invasive species and why there is a “price on its head.” The poster should include characteristics, last known location, “crime,” award, suspected sightings, etc.
  2. Create and produce a documentary depicting an affected ecosystem through an invasive species or human interaction.
  3. Create an original work of art that depicts an ecosystem affected by an invasive species or damaged through human interaction AND shows how the ecosystem could look through restorative actions, preservation, etc.
  4. Create a mock trial in which the invasive species is the defendant and the ecosystem is the plaintiff. The students will create a script that includes the “crimes,” evidence, attorneys’ dialogues, objections, verdict, etc.
  5. Create a community awareness program with the purpose of teaching the community the importance of protecting ecosystems.
  6. Create an informative Prezi, Smore, Weebly, or Symbaloo that reflects the research and learning. Follow all district policies and procedures prior to student usage of technology.

C. Communication

Each student or student group will present their findings related to the chosen topic. Students are expected to demonstrate and effectively communicate their research and provide substantive answers to the guiding questions through the product or performance chosen. Each student or student group will also be expected to answer questions from the audience regarding their research and product or performance.

D. A completed project consists of:

  1. A completed research proposal that includes guiding questions and answers
  2. A field journal with field observations, discoveries, proposals, etc.
  3. The product and/or performance
  4. Attachment #2 as appropriate
