Mapping Earth Systems

Overview

In this first lesson of the three-part unit “Earth Systems in Change,” students identify the geosphere, hydrosphere, atmosphere, and biosphere. They use short informational texts, maps, diagrams, and cause-and-effect cards to explain how matter and energy move among Earth’s systems, while citing evidence from sources.

Learning intentions

Students will be able to:

• Identify and describe the four major Earth systems.
• Extract information from maps, diagrams, and informational text.
• Explain one way Earth’s systems interact.
• Cite specific evidence to support a scientific explanation.

Success criteria

• I can correctly identify the geosphere, hydrosphere, atmosphere, and biosphere.
• I can use a visual and a text to describe an Earth-system interaction.
• I can draw arrows to show how matter or energy moves between systems.
• I can cite evidence by naming the source and quoting or describing relevant information.

Curriculum links

• Integrate technical information from text with information shown in diagrams, maps, and models.
• Compare information from visual and multimedia sources with information from scientific text.
• Cite specific textual evidence to support analysis of a science text.
• Determine central ideas, summarize informational text, and analyze how sections organize information.

Lesson structure (60 minutes)

1. 0–7 min · Hook and prior knowledge. Display a photograph of a rainstorm over a forest from the opening photo and hook question and ask, “How many parts of Earth are involved in this scene?” Students independently list visible or inferred Earth features, then share with a partner. Invite several responses without confirming all ideas yet.

2. 7–17 min · Build the system model. Use the four Earth systems teaching slides to introduce the systems: geosphere (solid Earth, rocks, soil, and landforms), hydrosphere (all water), atmosphere (the layer of gases surrounding Earth), and biosphere (living things). Students complete the four-box vocabulary section of the Earth systems evidence worksheet by recording a definition and one example for each system. Emphasize that a single place can include all four systems.

3. 17–27 min · Read and examine sources. Place students in four groups of three. Provide each group with a short, teacher-created source set containing one labeled landscape diagram, one simple map, and four short paragraphs about water, air, land, and living things. Model how to read a visual by identifying its title, labels, arrows, patterns, and key. Students annotate their source set and complete the “What does the source show?” prompts on the Earth systems evidence worksheet. Pause to ask groups to point to evidence rather than rely on prior knowledge.

4. 27–42 min · Map interactions. Give each group a different scenario, such as rain soaking into soil, plants releasing water vapor, sunlight warming ocean water, or erosion carrying soil into a stream. Students sort and connect the illustrated cause-and-effect cards in the Earth Systems Cause-effect Cards. They then add the interaction to the systems model on the Earth systems evidence worksheet, drawing labeled arrows for matter or energy movement. Each group must use at least two sources and record one piece of textual evidence and one piece of visual evidence.

5. 42–51 min · Group explanation and compare sources. Display the interaction discussion and comparison prompts. Each group gives a one-minute explanation using the frame, “The ___ system interacts with the ___ system when ___. The text says/shows ___. The diagram or map shows ___.” Classmates identify whether the text and visual provide the same information, different information, or additional information. Ask students to explain how the visual makes one detail easier to understand.

6. 51–57 min · Individual synthesis. Students independently complete the central-idea and evidence questions on the Earth systems evidence worksheet. They write a two- to three-sentence summary answering: “How do Earth’s systems work together in the scenario your group studied?” Require one cited detail from the text and one reference to the visual.

7. 57–60 min · Exit check. Show the final review and exit prompt. Students respond on the bottom of the worksheet: “Name two Earth systems and explain one way matter or energy moves between them. Cite one source detail.” Collect worksheets to identify misconceptions before Lesson 2.

Resources

• the Earth systems introduction, modeling, activity, discussion, and review deck
• the Earth systems evidence worksheet
• the Earth Systems Cause-effect Cards
• Teacher-created source sets with a labeled landscape diagram, map, and short informational texts
• Projector or interactive display
• Highlighters, pencils, and colored pencils
• Chart paper or whiteboard

Assessment

• Listen during group sorting for accurate system identification and correct use of matter and energy language.
• Check annotations and worksheet responses for evidence drawn from both text and visual sources.
• Use the exit response to assess system vocabulary, interaction reasoning, summary accuracy, and evidence citation.

Differentiation

• Provide a partially completed systems diagram, a word bank, color-coded source labels, and sentence frames for students who need support.
• Read the short texts aloud or provide teacher-recorded audio; pair developing readers with supportive peers and check understanding after each paragraph.
• Allow students with fine-motor or writing needs to dictate explanations, use speech-to-text, or label arrows with prepared terms.
• Challenge ready students to explain an interaction involving three systems or distinguish whether the movement represents matter, energy, or both.
