Keystone Species and Ecosystem Impact Slideshow

Grade 9Science2 days
This project-based learning experience is designed for 9th-grade science students, focusing on the critical role of keystone species in ecosystems. Throughout the project, students will research and analyze the ecological significance, conservation status, and threats faced by keystone species, as well as develop and communicate effective conservation strategies. Through activities like "Keystone Communicators" and "Biodiversity Advocate," students will engage in multimedia presentations and advocacy, aligning with NGSS standards, to deepen their understanding of ecosystem dynamics and biodiversity.

NGSS

HS-LS2-1
Primary
Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scalesReason: The project requires students to explain keystone species' roles and impacts on ecosystems, which involves understanding factors affecting carrying capacity.
HS-LS2-6
Primary
Evaluate claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.Reason: Students need to evaluate how keystone species interaction impact ecosystem stability; the project aligns as it explores ecosystem interactions.
HS-LS4-5
Primary
Evaluate the evidence supporting claims that changes in environmental conditions may result in changes in populations, which can influence the success of an organism within an ecosystem.Reason: Understanding threats to keystone species directly relates to evaluating evidence about environmental changes and their impacts.
HS-ESS3-4
Primary
Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.Reason: The project encourages students to examine and propose protection strategies for keystone species, aligning with evaluating solutions to impact reduction.

Entry Events

Events that will be used to introduce the project to students

Ecosystem Detective Adventure

Introduce an interactive adventure where students explore various ecosystems to uncover the mystery of which keystone species ensure the balance and health of each environment. Clues about different ecosystems are scattered, encouraging students to associate keystone species with the ecosystem they maintain.
