Revise, Explain, Predict

Overview

In this final lesson of Earth Systems in Motion, students revise a model of interactions among the geosphere, hydrosphere, atmosphere, and biosphere. They change one component, predict effects on the other spheres, and use data, visuals, and technical text evidence to present an explanation of feedback, matter flow, and energy transfer.

Learning intentions

Students will be able to:

• Revise an Earth systems model after changing one component.
• Predict how a change affects other Earth spheres.
• Integrate information from data, diagrams, and technical text.
• Explain a prediction using specific evidence and clear scientific reasoning.

Success criteria

• I can identify the component I changed and predict at least two effects.
• I can use evidence from a table, visual, or text to support my explanation.
• I can show matter flow, energy transfer, and feedback in my revised model.
• I can give an organized explanation that separates evidence from my opinion or prior knowledge.

Curriculum links

• Reading science and technical texts: cite specific textual evidence to support analysis.
• Reading science and technical texts: integrate quantitative or technical information with diagrams, models, and tables.
• Reading science and technical texts: compare information from a visual or model with information from a written text.
• Reading science and technical texts: determine central ideas and summarize accurately.

Lesson structure (45 minutes)

1. 0–5 min · Engage and recall. Teacher displays the question, “What might happen if one Earth system suddenly changed?” and opens the hook and review slides to revisit the four spheres, matter flow, energy transfer, and feedback. Students briefly discuss a possible change with a partner and identify which sphere is affected first.

2. 5–11 min · Model the thinking. Teacher demonstrates changing one component—for example, reduced vegetation in the biosphere—and thinks aloud while tracing likely effects on soil, water, and air. Students help identify arrows for matter movement, energy transfer, and possible feedback, then record one model-based prediction.

3. 11–15 min · Analyze evidence. Teacher distributes the evidence and model revision worksheet and uses the data, diagram, and technical-text slides to review how to cite evidence precisely. Students examine a short data table, a systems diagram, and a technical paragraph, highlighting one useful fact from each and distinguishing evidence from personal knowledge.

4. 15–28 min · Revise and predict. Teacher assigns pairs one Earth systems change and conferences with groups, asking, “What changes next? What evidence supports that arrow?” Students revise their existing model on the worksheet, adding labeled arrows for matter flow and energy transfer, at least two predicted effects, and one feedback connection. They cite evidence using the source and relevant detail.

5. 28–37 min · Prepare explanations. Teacher displays the explanation organizer and sentence-starter slides and models a concise claim-evidence-reasoning structure. Students prepare a one-minute presentation that states the change, summarizes the system response, cites at least two specific pieces of evidence, and explains one feedback loop.

6. 37–43 min · Present and compare. Teacher facilitates brief pair-to-pair presentations or four small-group presentation stations, using the prompts on the presentation and peer-feedback slides. Listening students record one similarity and one difference between the presenter’s model and the written evidence, then offer feedback on accuracy and clarity.

7. 43–45 min · Exit check. Teacher asks students to complete the final questions on the prediction and reflection section before collecting it. Students explain how one changed component could affect another sphere and cite one specific piece of evidence.

Resources

• the Earth systems revision slide deck
• the evidence and model revision worksheet
• Existing student Earth systems models from previous lessons
• Earth systems cause-effect cards for optional group assignment support
• Projector or interactive display
• Colored pencils or markers
• Timer
• Student science notebooks

Assessment

• During modeling and revision, check whether students trace effects across at least two spheres and label matter and energy arrows accurately.
• Review worksheets for a clear central explanation, specific evidence from the provided sources, and a distinction between evidence and prior knowledge or opinion.
• Use presentations and the exit check to assess whether students can compare visual and written information and explain feedback with scientific reasoning.

Differentiation

• Provide sentence starters such as “The data show…,” “The diagram indicates…,” and “Because matter moves from ___ to ___, ___ may happen.”
• Offer a partially completed model, a word bank for sphere names and processes, and color-coded arrows for students who need writing, reading, or organizational support.
• Read the technical paragraph aloud, allow students to annotate digitally or orally, and pair English learners with supportive peers; include icons beside key terms.
• Challenge ready students to identify a second feedback pathway, evaluate whether the evidence is sufficient, or explain a limitation in their prediction.
