Who this is for

Learners aged 14+ building subject foundations and practical independence. Adults can use the same supplied cases.

Prepare before lesson one
  • Use paper or a free text document; every core input is supplied in the lessons.
  • A basic calculator is optional; show the method, units and checks.
  • Suggested earlier course: Scientific Reasoning and Lab Readiness

What to include

  • Separate mineral, rock and geological process cards.
  • Draw a branching rock-cycle route with process labels.
  • Compare divergent, convergent and transform motion.
  • Interpret supplied earthquake/volcano patterns with an exception.
  • Distinguish hazard probability and post-onset warning from exact prediction.
  • Build a bounded landform evidence board and complete changed cases.

Review and revise

Use these criteria to check your work and choose what to improve.

  • Method: applies the course-specific rules to the supplied cases with visible intermediate work.
  • Accuracy: results agree with the stated facts, units, boundaries and independent checks.
  • Reasoning: explains why the result follows and identifies a limitation or unresolved question.
  • Transfer: completes changed cases and revises the final project when a relevant assumption changes.
Three ideas to help you along the way
Three useful ideas

The rules behind the steps.

01

Read the specific conditions

A mineral is a naturally occurring inorganic solid with an ordered structure and characteristic composition. A rock is an aggregate of minerals or other geological material. A process such as erosion changes or moves material; it is not itself a substance. Identification needs more than a color, and this course uses supplied cards rather than handling unknown samples.

02

Connect the mechanism

Divergent boundaries separate plates; convergent boundaries bring them together; transform boundaries have lateral motion past one another. At a supplied oceanic subduction case, one plate descends beneath another; not every convergent setting has identical features. Motion models describe geological processes, not a forecast for a specific day.

03

Explain evidence and limits

A geological explanation links materials, processes, motion and observations. Keep alternative explanations and missing evidence visible. A compatible model does not establish an exact age, future eruption date or structural safety. Use the supplied evidence rather than collecting or breaking rocks.

    Compare three plate-boundary motions

    Represent distinct boundary motions and qualify the supplied subduction example.

  4. 4
    10 min

    Use location patterns as geological evidence

    Use combined motion, depth and location evidence to compare boundary explanations.

  5. 5
    9 min

    Separate hazard, warning and precise prediction
