Mapping Earth Systems

Overview

In this lesson (10 of 18), students examine how technologies help scientists study tectonic activity and Earth’s changing systems. They compare tools, interpret data outputs, and explain how each technology improves understanding and prediction.

Learning intentions

Students will be able to:

• Identify key technologies used to investigate tectonic activity and Earth processes.
• Explain what each technology measures and how data supports scientific claims.
• Communicate findings using clear scientific language and visual information.

Success criteria

• I can name at least four technologies used in geology and describe their purpose.
• I can match a technology to the type of evidence it produces (for example, waves, images, measurements).
• I can explain how technology helps scientists understand patterns, causes, and impacts of Earth changes.
• I can create an infographic or response that is accurate and understandable for others.

Curriculum links

• Earth systems: investigating interactions between geological processes and Earth’s surface changes.
• Scientific inquiry: using evidence to develop and justify explanations.
• Data and models: interpreting and representing data from investigations and technological measurements.
• Science as a human endeavour: recognising how advances in technology improve investigation and understanding.

Lesson structure (60 minutes)

1. 0–5 min | Hook and retrieval

• Display a short scenario: “A city experiences repeated shaking and ground movement—how can scientists investigate what’s happening?”
• Students quick-write: “What tools would help us learn more?” (2 minutes), then share one idea.

2. 5–12 min | Mini-teach: technology toolkit

• Introduce 6–7 technologies commonly used in geology and hazard studies, including: seismometers/seismographs, GPS ground sensors, satellite remote sensing (InSAR), drone or aerial imagery, LiDAR, magnetometers/gravimeters, and geochemical sampling (as an example of Earth material investigation).
• Emphasise the link: technology produces evidence → evidence supports explanations about Earth processes.

3. 12–25 min | Stations: evidence–technology matching

• Split into pairs; rotate through 3 stations (about 4–5 minutes each), with one prompt per station:
• Station A: “Seismic waves” (simplified wave diagrams) → what it helps detect and measure.
• Station B: “Ground deformation maps” (colour-coded change contours) → what it suggests about movement.
• Station C: “High-resolution surface imagery” (before/after images) → what it helps observe about landform change.
• Each pair records: technology name, what it measures, and one example of a scientific question it answers.

4. 25–35 min | Whole-class synthesis: “How does it help?”

• Bring students together. Create a class table on the board: Technology | Evidence produced | Use in geology.
• Cold-call or use think-pair-share to ensure every group contributes.
• Teacher prompts: “What is the measured output?” “How could scientists use this to support a claim about tectonic activity?”

5. 35–47 min | Infographic task: simplify and explain

• Give each student (or pair) an infographic template with 4 boxes: technology, what it measures, evidence example, real-world use (hazard/monitoring/research).
• Students choose one technology from the class list and complete the infographic using their station notes.
• Provide a dyslexia-friendly option: allow oral dictation into a scaffolded template (single-sentence starters) rather than extended writing.

6. 47–55 min | Assessment check: gallery walk + “claim–evidence”

• Students post infographics. Students walk, using a simple feedback protocol:
• “One accurate technology use I noticed…”
• “One question I still have…”
• Teacher circulates with a quick checklist focused on identification and correct use.

7. 55–60 min | Exit ticket

• Students answer: “Choose one technology and explain how it provides evidence for tectonic activity in 2–3 sentences.”
• Collect for formative assessment.

Resources

• Technology cards or posters for: seismometers, GPS sensors, satellite InSAR (images of deformation), drone/aerial photos, LiDAR, gravimeters/magnetometers, geochemical sampling (optional).
• Station materials with simplified visuals (wave diagram, contour/deformation map, before/after surface images).
• Infographic templates (paper or digital offline).
• Coloured pencils/highlighters for evidence types and uses.
• Teacher checklist for quick formative assessment.
• Sentence starters for scaffolding (for example, “This technology measures…”, “The evidence shows…”, “Scientists use it to…”).
• Dyslexia-friendly option: audio recorder or teacher-led scribing sheet.

Assessment

• Formative: teacher checklist during station work and gallery walk feedback.
• Formative: exit ticket (accuracy in identifying technology and explaining its evidence use).
• Peer feedback quality: whether feedback refers to evidence and usefulness.

Differentiation

• Support (literacy): provide sentence starters, word banks (technology names, measurement/evidence/use phrases), and allow oral responses with teacher scribing.
• Support (concepts): use colour-coding on station prompts (one colour per evidence type).
• Extension (advanced learners): require an added “limitations/uncertainty” box (for example, what the technology cannot show directly, or how results must be interpreted carefully).
• EAL/SEN: reduce writing load by limiting to short phrases; add visuals and allow bilingual support where available; pre-teach one key verb per box (measures, detects, maps, compares, predicts).

Extension (optional)

• Create a brochure on a specific technology (choose from the same list used in stations), aimed at informing a local community about how the technology helps monitor tectonic hazards. Include: a simple explanation, a labelled diagram or image, one “real-world use” example, and one key limitation.
