Purpose

Students investigate how and why Earth’s surface changes over time by analyzing California’s four regions through a GLAD topographical pictorial, region cards, and a CCD vocabulary chart. Teams model erosion, examine volcanic activity, rock formations, and Ashfall fossil evidence, then design and compare solutions that reduce natural-process impacts on people. Through weekly self-assessment and peer critique, students revise maps, models, and fossil displays before selecting a final project. They present their evidence and solutions at an Earth Change Museum Night and respond to visitor questions using sentence frames.

Learning goals

Students will analyze California map data to identify the four geographic regions, major landforms, and patterns using a GLAD topographical pictorial and region cards. They will use observations from erosion models, rock formations, volcanic processes, and Ashfall fossils to explain how Earth’s surface changes over time. Students will define a natural-hazard design problem, develop and compare solutions using agreed-upon criteria and constraints, and revise their work through peer feedback. They will accurately use GLAD CCD vocabulary, communicate evidence during Earth Change Museum Night, and self-assess their learning goals after each lesson.

Standards
  • [California] 4-ESS3-2 - Generate and compare multiple solutions to reduce the impacts of natural Earth processes on humans.
  • [California] 3-5-ETS1-1 - Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
  • [California] 3-5-ETS1-2 - Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
  • [California] 4-ESS1-1 - Identify evidence from patterns in rock formations and fossils in rock layers to support an explanation for changes in a landscape over time.
  • [California] 4-ESS2-1 - Make observations and/or measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation.
  • [California] 4-ESS2-2 - Analyze and interpret data from maps to describe patterns of Earth’s features.
Competencies
  • Effective Communication - Students practice listening to understand, communicating with empathy, and share their learning through exhibiting, presenting and reflecting on their work.
  • Self Directed Learning - Students use teacher and peer feedback and self-reflection to monitor and direct their own learning while building self knowledge both in and out of the classroom.
  • Critical Thinking & Problem Solving - Students consider a variety of innovative approaches to address and understand complex questions that are authentic and important to their communities.
  • Collaboration - Students co-design projects with peers, exercise shared-decision making, strengthen relational agency, resolve conflict, and assume leadership roles.
  • Content Expertise - Students develop key competencies, skills, and dispositions with ample opportunities to apply knowledge and engage in work that matters to them.
  • Academic Mindset - Students establish a sense of place, identity, and belonging to increase self-efficacy while engaging in critical reflection and action.

Products

Students will co-create an annotated GLAD topographical California map and a CCD vocabulary chart featuring the four regions, landforms, rock formation, erosion, and volcanoes. Teams will build and document an erosion model, create an Ashfall Fossil Beds timeline showing landscape changes and prehistoric animals, and compare designs that reduce natural-process impacts on people. After a peer gallery walk, students will revise these products using sticky-note feedback and complete a learning-goal self-assessment. For Earth Change Museum Night, each student will choose a final product—such as a 3D model, illustrated field guide, narrated map, or hazard-solution prototype—and present it with labeled evidence and sentence frames.

Launch

Teams begin a “Map Quest” by exploring a giant topographical California relief map and placing cards for the Coast, Central Valley, Mountains, and Desert regions. They examine mystery clues—rock samples or images, erosion photos, volcano symbols, and Ashfall fossil replicas—to identify patterns and generate questions. Students add initial words and sketches to a GLAD CCD vocabulary chart, then share observations using sentence frames. The class launches the inquiry: “How and why does Earth’s surface change over time?”

Exhibition

Host an Earth Change Museum Night for families, classmates, and school staff. Student teams curate stations featuring the California topographical pictorial, erosion models, Ashfall fossil-bed timelines, GLAD CCD vocabulary highlights, and choice projects proposing ways to reduce natural-process impacts. Students rotate through roles as greeters, exhibit guides, model demonstrators, and question responders, using sentence frames and visual supports. Visitors leave feedback about evidence, clarity, and proposed solutions, and students complete a final learning-goal reflection.
