Plate Tectonics and the Rock Cycle | 8 Lessons, Case Cards & a Project | Grades 6–8

Plate Tectonics and the Rock Cycle is an earth science unit for Grades 6–8 with 33 pages of classroom material and a separate 13-page teacher guide. Students look at evidence for plate motion, the layers of the outer Earth, the three types of plate boundaries, rock types and paths through the rock cycle, and finish by writing evidence-based statements about natural hazards. It is written for middle school science teachers who want a self-contained unit with explanations, supported practice and reasoning cases.

The unit has eight lessons with the same three pages each: an explanation page, a practice page with explanation, and a case card. It starts with evidence for motion and the lithosphere and asthenosphere, then gives one lesson each to divergent, convergent and transform boundaries. The second half turns to rocks, with a lesson on rock types and one on rock-cycle paths. The last lesson uses the claim, evidence, reasoning pattern (CER) so students can support statements about hazards with evidence. A precise model and interpretation page, two vocabulary pages, a learning check and a short project with a reflection page complete the unit.

What's Included

• Classroom Material: 33 pages (PDF, print edition)
• Teacher Guide: 13 pages (PDF) with answers, case guidance and assessment feedback
• Editable DOCX text editions of the classroom material and the teacher guide
• Presentation with 17 slides (PPTX)
• Original illustrations and model diagrams; the PDF is the print reference and DOCX line breaks may differ
• Answers and teaching notes for all eight lessons, plus an assessment key with feedback, in the teacher guide

The 8 Lessons

• Lesson 1: Evidence for motion – Reviewing and weighing the evidence that plates move.
• Lesson 2: Lithosphere and asthenosphere – Telling the layers of the outer Earth apart.
• Lesson 3: Divergent boundaries – Plates moving apart and what follows from it.
• Lesson 4: Convergent boundaries – Plates moving toward each other and what follows from it.
• Lesson 5: Transform boundaries – Plates sliding past each other.
• Lesson 6: Rock types – Telling rock types apart and sorting examples.
• Lesson 7: Rock-cycle paths – Following the paths by which one rock type becomes another.
• Lesson 8: CER and hazards – Using claim, evidence and reasoning to support statements about hazards.

Students Will Learn To

• Evaluate evidence that the plates are moving
• Distinguish the lithosphere from the asthenosphere
• Describe divergent, convergent and transform boundaries
• Classify rock types and trace paths through the rock cycle
• Write a claim supported by evidence and reasoning about a natural hazard

Perfect For

• Grades 6–8 science teachers who need a closed earth science unit
• Teachers who want students to argue from evidence rather than memorize terms
• Classes that need a clear sequence from plate boundaries to rocks
• Homeschool families looking for printable lessons with a separate answer guide
• UK and Australia: roughly Years 7 to 9

Why Teachers Choose This Unit

• Each lesson follows the same explanation, practice and case card pattern
• The three boundary types each get their own lesson, so none is rushed
• A closing CER lesson gives students a structure for writing about hazards from evidence
• The teacher guide has a teaching concept, sequence and preparation notes, answers for all eight lessons, an assessment key with feedback, and a differentiation and observation chapter
• Editable DOCX text editions allow you to adapt wording for your class

Frequently Asked Questions

Which standards does this fit?

The content is closest to NGSS MS-ESS2 (Earth's systems) and MS-ESS3 (Earth and human activity). No alignment or endorsement is claimed.

Are answers included?

Yes. The separate 13-page teacher guide has answers and teaching notes for all eight lessons and an assessment key with feedback.

How long does the unit take?

The material does not state a duration. Plan by lesson: each has three pages, and you can use the lessons in order or choose the ones you need.

What does CER mean in this unit?

CER stands for claim, evidence, reasoning. In the final lesson students use it to support statements about hazards with evidence and a line of reasoning.
