Ecosystem Project Day

Overview

Students will engage in collaborative work focused on their ecosystem interdependence projects. This session emphasizes teamwork, application of scientific concepts about ecosystems, and refining communication skills through presentations. Students will also gather and organize materials to complete their projects effectively.

Standards Alignment

Next Generation Science Standards (NGSS):

• MS-LS2-1: Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.
• MS-LS2-2: Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.
• MS-LS2-4: Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.

Common Core State Standards (CCSS) - English Language Arts:

• CCSS.ELA-LITERACY.SL.6-8.1: Engage effectively in a range of collaborative discussions with diverse partners on grade-level topics, texts, and issues, building on others’ ideas and expressing their own clearly.
• CCSS.ELA-LITERACY.WHST.6-8.2: Write informative/explanatory texts, including the narration of scientific procedures or experiments, using precise language and domain-specific vocabulary.
• CCSS.ELA-LITERACY.SL.6-8.4: Present claims and findings, emphasizing salient points clearly and logically.

Learning Objectives

By the end of this lesson, students will be able to:

1. Collaborate effectively in groups to analyze and explain ecosystem interdependence. (CCSS.SL.6-8.1)
2. Collect and organize relevant data or resources that demonstrate understanding of ecosystem relationships. (NGSS MS-LS2-1, MS-LS2-2)
3. Refine and prepare a clear, organized presentation demonstrating their knowledge of ecosystem interdependence. (CCSS.SL.6-8.4)
4. Use scientific vocabulary accurately in written and oral communication related to ecosystems. (CCSS.WHST.6-8.2)

Materials Needed

• Ecosystem project kits/materials prepared in previous lessons (e.g., poster boards, markers, charts, printed images, digital tablets)
• Laptops/tablets for research and project refinement
• Rubrics for project assessment (printed)
• Classroom whiteboard and markers
• Timer or clock

Lesson Procedure

1. Warm-Up & Focus (5 minutes)

• Activity: Quick roundtable: Each group shares one key insight or question developed about interdependence within their ecosystem project.
• Purpose: Activate prior knowledge and set collaborative tone.
• Teacher role: Facilitate, ensuring all groups contribute briefly.

2. Project Work Session (35 minutes)

• Activity:

  • Students continue working in their previously assigned ecosystem groups.
  • They focus on:
    • Finalizing their ecosystem models or visual displays.
    • Organizing their research findings and data to support their arguments about interdependence.
    • Practicing interview-style questions and answers teammates might be asked during presentations.
  • Teacher circulates to monitor progress, provide targeted feedback, support use of scientific vocabulary, and help groups refine their scientific explanations.

• Teacher Tips:

  • Encourage use of scientific terms like "producers," "consumers," "decomposers," "food webs," "resource availability," and "population dynamics."
  • Suggest strategies for clear, logical presentation structure (e.g., introduction, body with evidence, conclusion).
  • Remind students to anticipate different types of audience questions and prepare to address them.

3. Collaborative Self-Assessment (5 minutes)

• Activity: Each group completes a brief rubric-based self-assessment regarding:
  • Clarity and accuracy of scientific content
  • Use of evidence to support explanations
  • Group cooperation and participation
• Purpose: Develop metacognitive awareness and group accountability.
• Teacher role: Collect rubrics for formative assessment.

4. Closing and Homework Preparation (5 minutes)

• Discussion: Quick reflection on progress and challenges faced during project work.
• Homework: Groups finalize their presentations/refine any incomplete parts (e.g., research, visuals) for next lesson (final presentations). Each student must also prepare a brief oral summary of one aspect of their ecosystem interdependence project.
• Teacher Role: Confirm that groups understand expectations, timeline, and offer support resources.

Assessment

Formative assessments during project work and group self-assessment rubrics will address:

• Ability to apply scientific concepts of ecosystem interdependence accurately
• Effectiveness of collaboration and communication skills
• Preparedness for final presentations

---

Differentiation & Accommodation

• Provide graphic organizers for students who need support in structuring information.
• Allow students to use technology for visual support if handwriting or drawing is challenging.
• Offer sentence starters for discussion and presentation practice, aiding English Language Learners.
• Group roles rotate to build confidence and accountability in all students.

---

Reflection for the Teacher

After the lesson, reflect on:

• Which groups showed strong understanding and collaboration?
• Was scientific vocabulary integrated naturally into explanations?
• Did students demonstrate readiness for final project presentations?
• Plan any additional scaffolding or mini-lessons based on gaps observed.

This structured yet student-driven session empowers middle schoolers to deepen their knowledge of ecosystem interdependence by practicing essential science inquiry and communication skills aligned with both NGSS and Common Core standards.
