Invasive Species |
Introduction
Invasive plants or animals can have a profound impact on ecosystems. When allowed to proliferate, they can kill off indigenous plant or animal life, causing whole natural habitats to change.
In this project, students identify an invasive species and
its impact on local ecosystems by doing research and performing
a quadrant study. Once students have assessed the health of
their local ecosystem, they will work with environmentalists
to devise a plan that will alleviate the invasive species
problem in their area.
This project incorporates elements of the scientific
method.
Grade level
Middle school, but can be adapted to suit other grades
Time allotment
Up to 1 semester
Subject matter
Main focus on environmental science, with language arts and
social studies connections
Learning objectives
Students will:
- Gain an understanding of the scientific method and use elements of it in some steps of the project.
- Research and discover which non-native plants exist locally.
- Study and analyze these invasive species' effect on the environment.
- Plan, publicize, and execute a project to help remove harmful invasives.

Assessment
Students will reflect on the results of their project by doing
one of the following options: make a scrapbook; create a video
or a Web page about their experiences to share with others;
or form groups to write a series of illustrated articles. Students
will also create and distribute an invasive species eradication
pamphlet to local government officials, media, schools, and
environmental groups.

impact of invasive species and the Federal government's
response. They can also read select species profiles and
find links to agencies and organizations dealing with invasive
species issues.
