Unit Plan 36 (Grade 6 Science): Cumulative Synthesis & Exhibition

Focus: Demonstrate mastery across space systems, Earth systems, natural hazards, weather/climate, human impacts, and engineering design by creating and presenting integrated models, explanations, data displays, and design proposals aligned with MS-ESS1, MS-ESS2, MS-ESS3, and MS-ETS1.

Grade Level: 6

Subject Area: Science (Earth & Space Science • Human Impact • Engineering Design)

Total Unit Duration: 5 sessions (one week), 50–60 minutes per session

I. Introduction

In this culminating unit, students curate and present a “Earth & Space Systems Expo” that showcases what they have learned across space systems (MS-ESS1), Earth processes (MS-ESS2), weather/climate and resources/hazards (MS-ESS3), and engineering design (MS-ETS1). Working in teams, they select a driving question or real-world challenge (e.g., “How can our community prepare for hazards and a changing climate?”) and build a multi-part display that combines models, data representations, written explanations, and a design solution. The week emphasizes systems thinking, cause–effect reasoning, and communicating science to an authentic audience.

Essential Questions

• How are space systems, Earth’s internal and surface processes, water and atmosphere, and human activities all connected in shaping conditions on Earth?
• How can models, data displays, and arguments from evidence help us explain and predict hazards, weather/climate patterns, and environmental changes?
• In what ways can engineering design help individuals and communities monitor, prepare for, or reduce impacts from natural hazards and human-caused environmental change?
• What does it mean to be an informed global citizen who understands Earth systems and takes responsible action?

II. Objectives and Standards

Learning Objectives — Students will be able to:

1. Synthesize learning from MS-ESS1, MS-ESS2, and MS-ESS3 by constructing a coherent Earth & Space Systems model that shows key components (e.g., Earth–Sun–Moon, rock cycle/plate tectonics, water cycle, atmosphere/oceans, human systems) and interactions among them.
2. Use data displays (graphs, maps, diagrams, tables) to explain patterns in space motion, Earth processes, weather/climate, natural hazards, or resource use, citing evidence appropriately.
3. Explain at least one natural hazard or environmental challenge using systems thinking, showing how multiple Earth systems and/or human decisions contribute to risks and impacts.
4. Apply the engineering design process (MS-ETS1) to define a realistic design problem, specify criteria and constraints, and propose or refine a solution that reduces risk or minimizes environmental impact.
5. Communicate their findings in a Cumulative Synthesis & Exhibition product (poster, model, demo, or digital display) that integrates models, data, explanations, and design proposals for a target audience.

Standards Alignment — 6th Grade (NGSS-based custom)

• MS-ESS1 (Space Systems) — Students connect Earth–Sun–Moon motions, seasons, eclipses, gravity, and solar system scale to conditions on Earth.
• MS-ESS2 (Earth Systems) — Students integrate ideas about the rock cycle, plate tectonics, surface processes (weathering, erosion, deposition), water cycle, weather, climate, and global circulation.
• MS-ESS3 (Earth & Human Activity) — Students synthesize learning on natural hazards, resources and settlements, human impacts, climate change, and sustainability/stewardship.
• MS-ETS1 (Engineering Design) — Students use design practices (problem definition, criteria/constraints, evaluating/testing designs, and iterating with models/data) to propose hazard-resilient or environmentally responsible solutions.

Success Criteria — Student Language

• I can create and explain a systems model that shows how at least two major Earth systems and one human activity interact.
• I can use data (graphs, maps, charts, tables) to support my explanation of a space/earth/hazard/climate pattern.
• I can describe a real hazard or environmental issue and explain how multiple factors in Earth systems and human decisions contribute to it.
• I can define a design problem with clear criteria and constraints and propose a reasonable solution.
• I can present my Exhibition product clearly so that an audience understands my models, data, and solution.

III. Materials and Resources

Tasks & Tools (teacher acquires/curates)

• Reference resources (from earlier units):
  • Diagrams/models of the Earth–Sun–Moon system (phases, eclipses, seasons).
  • Rock cycle diagrams and plate boundary maps (earthquakes, volcanoes, mountain ranges).
  • Maps/visuals for natural hazards, weather and climate zones, water cycle, global circulation.
  • Data sets: simplified temperature/precipitation graphs, CO₂ or climate trends, hazard frequency maps, resource and population maps.
• Expo project tools:
  • Large poster paper or trifold boards; markers, sticky notes, index cards.
  • Modeling materials (paper, cardboard, clay, pipe cleaners, string, colored beads for cycles/flows).
  • Devices or printouts for digital graphing/mapping (if available) or teacher-provided graphs.
  • Project planning organizers:
    • “Driving Question & Systems Map” organizer.
    • “Evidence & Data” table (what data, what pattern, what it shows).
    • “Engineering Design Brief” template (problem, criteria, constraints, solution sketch, trade-offs).
    • “Exhibition Planner” (sections for model, data, explanation, design solution).
• Anchor charts (from previous units or recreated):
  • “Earth Systems & Spheres” (geosphere, hydrosphere, atmosphere, biosphere).
  • “Hazards & Human Impacts” (what we can monitor, prepare for, or reduce).
  • “Engineering Design Cycle” (Define → Plan → Create → Test/Improve).
  • “Strong Scientific Explanations & Arguments” (claim–evidence–reasoning).

Preparation

• Decide on presentation format (in-class gallery walk, invited audience, or digital slideshow/poster share).
• Pre-select several sample driving questions or themes, such as:
  • “How can communities prepare for earthquakes/volcanoes/floods/hurricanes?”
  • “How might climate change affect local weather or hazards, and what can people do?”
  • “How do space systems and Earth systems together control seasons and climate in our region?”
  • “How can our school reduce its environmental impact while staying safe from hazards?”
• Prepare rubric copies (aligned with the summative assessment) to share with students at the start of the week.

Common Misconceptions to Surface

• “Each topic (space, rocks, weather, climate, humans) is separate.” → Emphasize Earth as a system of systems, with interactions.
• “Hazards are completely random and nothing can be done.” → Revisit how patterns and data are used to forecast and engineer safer systems.
• “Climate is just today’s weather.” → Reinforce long-term patterns and connections to global circulation and energy.
• “Engineering is only for building machines.” → Highlight engineering as defining problems, designing, testing, and improving solutions to real-world challenges, including environmental ones.

Key Terms (highlight in lessons) system, interaction, Earth system, space system, rock cycle, plate tectonics, natural hazard, water cycle, weather, climate, human impact, resource, mitigation, adaptation, criteria, constraints, design solution, model, evidence, data, trade-off, prediction

IV. Lesson Procedure

(Each day follows: Launch → Explore/Work Time → Discuss → Reflect. Timing for a 50–60 minute block.)

Session 1 — Launching the Earth & Space Systems Expo (All Strands)

• Launch (8–10 min)
  • Briefly revisit the year’s major Earth & Space topics (space systems, Earth processes, water & weather, climate/human impacts, engineering).
  • Show a simple systems web connecting Sun–Earth–Moon, rock cycle/tectonics, water/air, and human systems. Ask: “Where do you see connections among these?”
  • Introduce the “Earth & Space Systems Expo” culminating project and share the rubric.
• Explore (25–30 min)
  • In small groups, students select a driving question or challenge from a teacher-provided list or propose one (with approval).
  • Using the Driving Question & Systems Map organizer, they:
    • Identify which standards/strands (MS-ESS1, MS-ESS2, MS-ESS3, MS-ETS1) are most relevant.
    • Sketch a systems map with key components (Sun/Earth/Moon, geosphere, hydrosphere, atmosphere, biosphere, human activities) and arrows showing interactions.
    • Note at least one data source or model they might include (e.g., hazard map, climate graph, cycles diagram).
• Discuss (8–10 min)
  • Groups share their driving question and a quick description of their systems map. Teacher ensures all major strands are represented across the class.

  • Exit ticket: “Our group’s driving question is __. One important system interaction we will show is __ → __ because __.”

Session 2 — Revisiting Space & Earth Systems with Data and Models (MS-ESS1, MS-ESS2)

• Launch (6–8 min)
  • Quick “carousel review”: show 3–4 stations labeled Space Systems, Earth’s Interior & Plates, Surface Processes/Water. Ask: “Which pieces of evidence from these topics could help answer your driving question?”
• Explore (25–30 min)
  • Groups rotate through review stations or access a menu of mini-resources:
    • Space Systems Station: Earth–Sun–Moon diagrams, seasons/eclipses models, gravity/orbits visuals.
    • Geoscience Station: rock cycle, plate boundary maps, earthquake/volcano data, mountain-building diagrams.
    • Water & Surface Station: water cycle diagrams, weathering/erosion visuals, river/floodplain maps.
  • At each station, groups identify at least one model or data source they will adapt or reference in their expo product and record:
    • What it shows (pattern or process).
    • How it connects to their driving question.
• Discuss (8–10 min)
  • Whole-class: share examples of how space and Earth systems evidence can support their chosen challenge (e.g., “We’ll use plate boundary maps to explain our earthquake risk.”).

Session 3 — Hazards, Climate, and Human Impacts in Context (MS-ESS3, MS-ETS1)

• Launch (6–8 min)
  • Show a simple hazard or climate-related scenario (e.g., coastal flooding, drought, severe storms, wildfire risk). Ask: “How do Earth systems AND human choices influence the risk and impacts here?”
• Explore (25–30 min)
  • Provide hazard/climate/human impact resources (maps, graphs, short readings) matched to groups’ topics:
    • Natural hazards: earthquakes, volcanoes, tsunamis, hurricanes, floods, droughts.

    • Human impacts: land use, resource extraction, emissions, infrastructure, protective measures.
  • Groups update their project plans to include:
    • A hazard or environmental risk connected to their driving question.
    • At least one data display they will create or adapt (graph, map, chart).
    • A design problem statement (MS-ETS1) that defines who is affected, what needs to be improved, and why.

V. Differentiation and Accommodations

Advanced Learners

• Encourage them to incorporate multiple data displays (e.g., a map and a graph) and explicitly compare patterns.
• Ask them to include a quantitative goal or prediction in their design solution (e.g., “This measure could reduce flood damage by __%,” “This change could lower energy use by __ over a month”).
• Invite them to integrate at least two major strands (e.g., space systems + climate, or plate tectonics + hazards + human settlement patterns) in a more complex systems model.

Targeted Support

• Provide scaffolded templates with partially filled sections for the systems model and design brief.
• Allow smaller-scope driving questions that focus on a local or single-system issue, as long as basic connections are made.
• Offer sentence frames, such as:
  • “Our model shows that when __ happens in the __ system, it affects __ by __.”
  • “The data in this graph shows __, which means __ for our problem.”
  • “Our solution helps because __, even though we are limited by __.”

Multilingual Learners

• Allow planning in students’ home languages and support translation of key ideas into English for final products.
• Use visual scaffolds: icons, color-coding for different systems (space, rocks, water, air, humans), and bilingual word banks where possible.
• Accept labeled diagrams, bullet lists, and short phrases in place of longer paragraphs, as long as the scientific meaning is clear.

IEP/504 & Accessibility

• Break the project into smaller checkpoints with explicit deadlines and teacher conferences.
• Provide options for alternative formats, such as recorded video explanations, audio presentations, or simple 3D models with brief captions.
• Ensure physical materials and room setup accommodate mobility, sensory, and processing needs (clear pathways, quiet zones, larger print, visual timers).

VI. Assessment and Evaluation

Formative Checks (daily)

• Session 1 — Driving Question & Systems Maps show a reasonable challenge and at least two connected systems/components.
• Session 2 — Station notes identify relevant models/data and correctly describe what they show.
• Session 3 — Hazard/impact focus and design problem statements include who is affected and why it matters; early criteria/constraints appear.
• Session 4 — Draft models, data displays, and design briefs are present in rough form and aligned with the rubric.
• Session 5 — TAG feedback from peers demonstrates understanding of criteria and encourages revision/extension.
