Future Earth Changes

Overview

This 50-minute lesson for 6th-grade science students is Lesson 21 in the “Tectonic Forces Unleashed” unit. Students will explore the future of plate tectonics, including how tectonic plate movement can shape Earth’s surface over millions of years. Through interactive discussion, visualization, and collaborative modeling, students will learn to predict geological events and connect this with scientific explanations aligned with the Common Core State Standards for Science.

Learning Objectives

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

• Describe how plate tectonics will continue to shape Earth’s surface in the future
• Predict possible geological events such as mountain formation, earthquakes, and volcanic activity based on plate movement
• Explain how scientific models and evidence help scientists understand future tectonic activity
• Engage in collaborative discussions demonstrating use of scientific language and evidence

Standards Alignment

This lesson aligns with the following Common Core and Next Generation Science Standards (NGSS) for 6th grade:

• MS-ESS2-1: Develop a model to describe the cycling of Earth's materials and the flow of energy that drives this process
• MS-ESS2-2: Construct an explanation based on evidence for how geoscience processes have changed Earth’s surface at varying time scales
• ELA-LITERACY.SL.6.1: Engage effectively in a range of collaborative discussions with diverse partners on grade 6 topics, building on others' ideas and expressing their own clearly
• ELA-LITERACY.RST.6.3: Follow precisely a multistep procedure when carrying out experiments or performing technical tasks

Materials Needed

• Large world map or globe
• Colored markers or sticky notes
• Whiteboard and markers
• “Future Plate Tectonics” scenario cards (prepared in advance)
• Printed worksheet: “Predicting Earth’s Future: Plate Movement”
• Projector for short animation/video clip (optional) demonstrating tectonic plate movement over time

Lesson Structure

1. Introduction & Review (10 minutes)

• Begin with a brief interactive review of tectonic plates' current movement and their effects (mountain building, earthquakes, volcanoes).
• Ask: “What do you think happens to Earth millions of years from now because of plate tectonics?” to activate prior knowledge.
• Show a brief animation illustrating past tectonic movements and their impact on Earth’s surface.

2. Direct Instruction & Explanation (10 minutes)

• Explain that Earth's surface is always changing due to plate movements and these changes will continue into the future.
• Introduce three main geological events that may occur in the future: formation of new mountain ranges, earthquakes, and volcanic eruptions.
• Highlight scientific models – how scientists use evidence from current plate movements to predict future changes.
• Use the world map or globe to show major tectonic boundaries and demonstrate possible future movements (e.g., closing or opening of ocean basins).

3. Collaborative Group Activity: Predict the Future (20 minutes)

• Divide students into 4 groups (5 students each).
• Each group receives one “Future Plate Tectonics” scenario card describing a different plate boundary (convergent, divergent, transform) and a region of the world.
• Task: Using the map and markers, groups must:
  • Predict geological events that might happen in their assigned area in the next 10 million years.
  • Draw and label expected changes (e.g., new mountains, earthquakes zones).
  • Discuss and write down reasoning based on plate movement and forces.
• Teacher circulates and supports groups, encouraging use of science vocabulary and evidence-based predictions.

4. Group Presentations & Class Discussion (8 minutes)

• Each group briefly presents their model and predictions (2 minutes per group).
• Class provides constructive feedback and asks questions, fostering scientific discourse.
• Teacher emphasizes connections between models, evidence, and scientific explanations.

5. Exit Ticket & Wrap-Up (2 minutes)

• Students complete a quick written prompt on a sticky note:
  “One way Earth’s surface could change in the future because of plate tectonics is...”
• Collect responses for formative assessment to check understanding.

---

Assessment and Reflection

• Formative: Observations during group discussions, accuracy and detail of group predictions and models, exit ticket responses.
• Summative: Will be built into Lesson 24 (final review and test on plate tectonics in the unit).
• Reflection: After lesson, teacher notes what went well and what could be improved, especially looking at student engagement with scientific argumentation and model development.

---

Differentiation

• For ELL/Special Needs: Provide simplified scenario cards with visuals; pair students for peer support; allow drawing as a form of explanation.
• For Advanced Students: Challenge to connect future tectonics to climate or ecosystem changes; encourage research on supercontinents like “Pangaea Proxima.”

---

Extensions/At-Home Connections

• Students can interview family members about experiences with earthquakes or volcanoes and bring stories to class.
• Optional home research: Create a digital or physical poster about a tectonic boundary and potential future changes.

This lesson leverages visual, collaborative, and explanatory strategies grounded in NGSS and Common Core standards to create a future-focused understanding of Earth sciences, inspiring curiosity and scientific thinking in 6th graders.
