🌎 Part 1: Earth Systems Evidence

Word bank: atmosphere · geosphere · hydrosphere · biosphere · matter · energy · erosion · evaporation

1. Label the four Earth spheres in the diagram. Add one example to each sphere.

Sphere labels to include: atmosphere, geosphere, hydrosphere, biosphere.

Read the technical text.

Rain falls from the atmosphere into rivers and soil in the hydrosphere. Moving water can carry soil and rock, causing erosion in the geosphere. Plants in the biosphere use water, carbon dioxide, and sunlight to grow. Dark, wet soil may become cooler during rain, while sunlight can warm dry land. These changes show that matter and energy move among Earth’s spheres.

2. In the text, what process moves soil and rock from one place to another?

erosion

evaporation

plant growth

3. Complete the data connections. Write the matching measurement and visual letter beside each statement.

Data: After a storm, rainfall measured 2.4 inches, river flow increased to 180 cubic feet per second, exposed soil decreased by 10%, and the shaded ground temperature was 68°F.

Visuals: A = rain clouds over a river; B = a plant with deeper roots; C = a cooler, shaded soil surface.

1. More water moved through the river.

2. Plants can hold soil in place.

3. Wet, shaded ground was cooler.

180 cubic feet per second; Visual ____

10% less exposed soil; Visual ____

68°F; Visual ____

4. Use two specific pieces of evidence from the text or data to explain how at least two spheres interacted.

Sentence starter: The data show __________ because __________.

⚡ Part 2: Energy-and-Matter Pathway

Choose one event: coastal erosion, volcanic eruption, or the water cycle.

5. Complete the pathway diagram for your chosen event. Include all four spheres, arrows showing matter movement, arrows showing energy movement, and the main energy source.

6. Identify the main energy source for your event.

energy from the Sun

heat from Earth’s interior

both sources

7. Explain one arrow in your pathway. State what moves and where it moves.

Sentence starter: Energy or matter moves from __________ to __________ because __________.

🧩 Part 3: Systems-Model Design and Exit Ticket

Model procedure: 1) Define the system. 2) Add all four spheres. 3) Draw at least six labeled connections. 4) Use arrows for matter and energy. 5) Identify an energy source. 6) Add a change. 7) Predict an outcome. 8) Revise after feedback.

8. Design your systems model. Choose one change: increased rainfall, loss of vegetation, rising surface temperature, or volcanic activity.

Checklist: ☐ four spheres ☐ six labeled connections ☐ matter arrows ☐ energy arrows ☐ energy source ☐ predicted change

9. Peer feedback: What is one clear connection and one missing or unclear connection in your partner’s model?

10. Revision note: What did you change in your model after receiving feedback? How did the revision improve your explanation?
