Investigating Local Geology

Overview

In this 50-minute lesson, 6th-grade students will investigate local geological features and analyze how these features relate to plate tectonics. This lesson is designed to build students' research, collaboration, and critical thinking skills through inquiry-based learning aligned to Common Core State Standards and Next Generation Science Standards (NGSS).

Standards Alignment

Common Core State Standards (CCSS)

• CCSS.ELA-LITERACY.RST.6-8.1
  Cite specific textual evidence to support analysis of science and technical texts.
• CCSS.ELA-LITERACY.WHST.6-8.7
  Conduct short research projects to answer a question (including a self-generated question), drawing on several sources and generating additional related, focused questions for further research and investigation.
• CCSS.ELA-LITERACY.SL.6.1
  Engage effectively in a range of collaborative discussions with diverse partners on grade 6 topics, texts, and issues, building on others' ideas and expressing their own clearly.

Next Generation Science Standards (NGSS)

• MS-ESS2-2
  Construct an explanation based on evidence for how geoscience processes have changed Earth's surface at varying time and spatial scales.
• MS-ESS2-3
  Analyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of past plate motions.

Learning Objectives

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

1. Identify at least three significant local geological features and describe their characteristics.
2. Explain how plate tectonic processes contributed to the formation of these local features.
3. Use credible scientific sources to gather information and support their explanations with evidence.
4. Collaborate to create a short presentation summarizing their findings clearly and effectively.

Materials Needed

• Student computers or tablets with internet access (or print resources about local geology)
• Google Earth or an alternative map software (optional)
• Chart paper and markers
• “Local Geological Features” research worksheet (template provided by teacher)
• Projector or interactive board
• Timer or visual timer

Lesson Activities

1. Engage (5 minutes)

• Begin with a captivating image slideshow of local geological features (mountains, fault lines, volcanoes, river valleys).
• Ask guiding questions:
  • “What do you notice about these places?”
  • “Have you ever visited any of these local spots?”
  • “What do you think caused these features to form?”
• Briefly remind students about plate tectonics as the driving force behind Earth's surface changes.

2. Explore & Research (20 minutes)

• Divide students into small groups of 4 (5 groups total).
• Assign each group a different local geological feature (e.g., a nearby mountain, canyon, fault line, volcano).
• Distribute the “Local Geological Features” worksheet to guide research:
  • Feature name and location
  • Description and observable characteristics
  • Hypothesis about tectonic forces involved (convergent, divergent, transform plate boundaries)
  • Evidence found in their research supporting their explanations
• Students use a mix of provided printed materials and safe online resources to gather information.
• Teacher circulates, encourages questioning, scaffolds research skills, and ensures on-task behavior.

3. Explain (10 minutes)

• Each group prepares a quick 2-minute presentation synthesizing their findings.
• They should focus on answering:
  • What is the geological feature?
  • How was it likely formed by plate tectonics?
  • What evidence supports their conclusion?
• Use chart paper or a digital slide to highlight key points.

4. Elaborate & Discuss (10 minutes)

• Groups present their findings to the class.
• After each presentation, invite one or two clarifying questions from peers to promote engagement and deepen understanding.
• Facilitate a brief discussion on how different types of plate boundaries create distinct geological features locally.

5. Evaluate (5 minutes)

• Individual Exit Ticket: Students write a short paragraph answering:
  • “Choose one local feature discussed today. How did plate tectonics shape it? Use evidence to support your answer.”
• Collect exit tickets as a formative assessment of student understanding.

Differentiation & Extensions

• For struggling learners: Provide a simplified research sheet with key vocabulary and sentence starters. Pair with a peer mentor.
• For advanced learners: Challenge to suggest how future tectonic movements might alter local features or predict geological hazards.
• Extension activity: Plan a field trip or virtual tour using Google Earth to observe these features firsthand and connect classroom learning to real-world geography.

---

Assessment

• Formative assessment through observation of group collaboration and presentations.
• Exit ticket analysis to check individual understanding.
• Informal oral questioning during discussion.

Reflection for Educators

Post-lesson, reflect on how students engaged with inquiry and research. Were they able to make connections between geology and evidence? Adjust support or scaffolding for future lessons to deepen understanding of tectonic processes and earth science literacy.

By connecting plate tectonics to local geography, students gain tangible, memorable insights into Earth's dynamic systems, building foundational science literacy as aligned with Common Core and NGSS standards.
