Discovering Biodiversity

Overview

In this 180-minute STEM lesson, 9th-grade students will explore biodiversity through the lens of "David Attenborough: A Life on Our Planet." The lesson will utilize a jigsaw teaching strategy, ensuring active participation from every student. This lesson aligns with the Next Generation Science Standards (NGSS) for high school environmental science.

Objectives

• Understand the impact of human activity on biodiversity.
• Analyze concepts related to ecosystems and natural resources.
• Develop skills in teamwork, communication, and critical thinking.
• Synthesize information from different perspectives to gain a comprehensive understanding of global biodiversity challenges.

Curriculum Standards

NGSS (9-12):

• HS-LS2-7: Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.
• HS-ESS3-4: Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.

Materials Needed

• "David Attenborough: A Life on Our Planet" documentary
• Projector and audio system
• Four large whiteboards or large poster paper and markers
• Printed copies of jigsaw reading materials
• Student notebooks
• Access to laptops or tablets (if available)

Lesson Structure

Introduction (15 minutes)

1. Context Setting (10 minutes):

   • Brief introduction to David Attenborough and the significance of his work in environmental science.
   • Define biodiversity and its importance to ecosystems and human survival.

2. Preview Film Highlights (5 minutes):

   • Show a short clip from the documentary highlighting one key theme: biodiversity loss due to human impact.

Jigsaw Activity (90 minutes)

1. Form Jigsaw Groups (10 minutes):

   • Divide students into "home groups" of four, ensuring diverse ability levels.
   • Assign each student a number from 1 to 4 within each group.

2. Expert Group Work (30 minutes):

   • Direct all students with the same number to form "expert groups."

   • Each "expert group" will focus on one specific aspect from the film:

     • Group 1: Human Impact on Ecosystems
     • Group 2: Role of Biodiversity in Ecosystem Services
     • Group 3: Consequences of Biodiversity Loss
     • Group 4: Solutions and Innovations

   • Provide printed reading materials and discussion questions specific to their topic. Allow time for groups to prepare a short summary presentation.

3. Return to Home Groups (25 minutes):

   • Students return to their original "home groups" to share insights from their "expert group."
   • Each student presents their topic for 3-5 minutes.

4. Group Question Time (25 minutes):

   • Allocate time for each student to ask two questions about the other topics they learn from peers to deepen understanding.
   • Encourage notes in their notebooks for use in the final activity.

Synthesis and Discussion (45 minutes)

1. Class Discussion (20 minutes):

   • Facilitate a whole-class discussion on students' findings and reflections on how each topic interconnects.
   • Prompt students to consider how their daily lives impact biodiversity and what actions can be adopted to mitigate these effects.

2. Solution Design Challenge (25 minutes):

   • Students work in their "home groups" to design a practical solution for biodiversity conservation relevant to their community or school.
   • Solutions can be presented as posters, digital presentations, or verbal pitches.

Conclusion (30 minutes)

1. Present Solutions (20 minutes):

   • Groups share their conservation solutions with the class.
   • Provide constructive feedback and encourage peer-to-peer learning.

2. Reflection (10 minutes):

   • Students write a reflective journal entry on what they learned, how they can contribute to biodiversity conservation, and their thoughts on the documentary.

Assessment

• Active participation in expert and home groups.
• Quality and creativity of the group solution design.
• Engagement and insight during the class discussion.
• Reflective journal entry evaluation based on clarity, depth, and personal connection to the topic.

By the end of this lesson, students will not only gain a deeper understanding of biodiversity issues but also develop practical skills in collaboration and problem-solving in the context of real-world challenges.
