Earth Systems in Motion

Overview

Students investigate how Earth’s atmosphere, geosphere, hydrosphere, and biosphere interact to cycle matter and energy and shape Earth’s surface. They analyze data, follow a multistep modeling procedure, and construct evidence-based explanations about energy sources and feedback in Earth systems.

Learning intentions

Students will be able to:

• Analyze data to identify evidence of interactions among Earth’s four major spheres.
• Explain how matter and energy flow among system components.
• Distinguish between energy from the Sun and heat from Earth’s interior.
• Develop and use a model to show how changes in one component affect other components.
• Use evidence from text, visuals, and data to support a scientific explanation.

Success criteria

• I can identify the atmosphere, geosphere, hydrosphere, and biosphere in a diagram or real-world event.
• I can use data and specific evidence to explain how Earth’s spheres interact.
• I can trace energy and matter through an Earth system and identify its energy source.
• I can create and revise a model that predicts how a change in one sphere affects another.

Curriculum links

• Integrating quantitative and technical information from text with diagrams, models, graphs, and tables.
• Introducing and organizing a scientific topic using headings, graphics, and clearly grouped ideas.
• Citing specific textual evidence from science and technical texts.
• Following a precise multistep procedure during a scientific modeling task.
• Gathering, evaluating, paraphrasing, and citing information from multiple print and digital sources.

Lesson structure (225 minutes)

1. 0–15 min · Engage with a systems puzzle. Teacher opens with the hook and Earth-systems image and displays a striking before-and-after image of a river valley after heavy rain, asking, “How could one event change land, water, air, and living things?” Students make an initial claim, identify visible evidence, and share one question.

2. 15–45 min · Build the Earth-systems framework. Teacher uses the four-spheres teaching slides to define atmosphere, geosphere, hydrosphere, and biosphere, modeling how one event can involve all four; students annotate the Earth-systems analysis worksheet by labeling a diagram and recording examples of matter moving between spheres. Pause for checks: students hold up the sphere they think is most directly involved in each example.

3. 45–80 min · Read, interpret, and connect data. Teacher distributes the data table, short technical text, and visual comparison and guides students through a short reading about rainfall, erosion, plant growth, and surface temperature. Students work in pairs to match statements, measurements, and visual representations, then cite two specific pieces of evidence showing sphere interaction. Teacher checks that students distinguish observations from explanations.

4. 80–95 min · Break and reset. Students take a supervised break, then return with materials ready for modeling.

5. 95–135 min · Trace energy and matter. Teacher presents the energy-flow and matter-cycle slides and explains that sunlight drives many surface processes while heat from Earth’s interior drives processes such as tectonic movement and volcanic activity. In groups of four, students use a teacher-provided event choice—coastal erosion, volcanic eruption, or the water cycle—to complete the flow diagram on the energy-and-matter pathway page. Each group must mark the four spheres, arrows for matter movement, arrows for energy movement, and the main energy source or sources. Groups explain one arrow to a partner group.

6. 135–195 min · Develop and test a systems model. Teacher displays the model-building procedure and success criteria and explicitly models the required sequence: define the system, identify components, add arrows, label matter and energy, introduce a change, predict an outcome, and revise using evidence. Students construct a model on the final page of the systems-model design sheet showing a change such as increased rainfall, loss of vegetation, rising surface temperature, or volcanic activity. Their model must include all four spheres, at least six labeled connections, an energy source, and a prediction. Students then exchange models, follow the arrows, and write feedback identifying one clear connection and one missing or unclear connection. Authors revise their models.

7. 195–225 min · Explain and assess. Teacher uses the discussion and exit-ticket slides to facilitate a whole-class comparison of models. Students present a concise claim-evidence-reasoning explanation: “A change in ___ affects ___ because ___.” They complete the exit ticket on the individual explanation and reflection: identify evidence for interaction among the spheres, explain the role of one energy source, and describe how feedback from a model test led to a revision.

Resources

• Earth systems and modeling slide deck
• Earth systems analysis and modeling packet
• Projector or interactive display
• Student science notebooks
• Colored pencils or markers
• Chart paper or large construction paper
• Sticky notes
• Timer
• Optional classroom reference texts or approved digital articles

Assessment

• During discussion and pair work, listen for accurate use of sphere names and ask students to point to evidence in the text, table, or visual.
• Check group flow diagrams and models for four spheres, correctly directed matter and energy arrows, and a justified prediction.
• Use the exit ticket to assess evidence citation, identification of an energy source, and explanation of model revision.

Differentiation

• Provide a partially labeled sphere diagram, a word bank, color-coded arrow examples, and sentence starters such as “The data show ___ because ___” and “Energy moves from ___ to ___.”
• Pair students strategically and assign roles: reader, evidence finder, model designer, and discussion reporter. Read the technical text aloud or provide text-to-speech access as needed.
• For English learners, preview terms with icons and gestures, allow annotated drawings before writing, and accept oral rehearsal with a partner.
• For students needing additional support, offer only two event choices and a teacher conference using a checklist. Challenge advanced students to include a feedback loop and compare the roles of solar energy and internal Earth heat.
