Understanding Plate Tectonics: Earth's Movable Crust and Its Implications

This unit delves into the dynamic processes of plate tectonics, highlighting the Earth's crust's structure and mobility. Essential questions explore whether present geologic activities mirror those of the past and if they will continue in the future. Aligned with Earth and Space Science standards for grades 5-7, this curriculum helps students grasp the concepts of Earth's interior, earthquakes, and volcanic activity while confronting common misconceptions about plate movement. Engaging activities, such as modeling Earth’s interior and exploring Pangaea, foster comprehension of these fundamental geological processes.

Presentation Transcript

  1. Plate Tectonics Group 2A

  2. Enduring Understanding • The processes that are occurring suggest that the Earth’s crust is made of movable plates.

  3. Essential Question • Have today’s geologic processes occurred in the past? • Could today’s geologic process occur in the future?

  4. Standards Link • Standard 4: Earth and Space Science Grades 5-7 • Benchmark 2: The student will understand past and present earth processes and their similarity. • Indicator 1: Understands that earth processes obtained today are similar to those that occurred in past; earth history is also influenced by occasional catastrophes, such as the impact of a comet or asteroid.

  5. Background Knowledge • Basic understanding of earth structure • Basic understanding of earthquakes and volcanoes

  6. Misconceptions Students typically do not believe that: • The Earth is made of plates • The plates move

  7. Sequence of Activities • Activity 1 – Models of Earth’s Interior • Activity 2 – Flexohexagram • Activity 3 – Pangaea Puzzle • Activity 4 – Drifting Away • Activity 5 – Plate Boundaries (Seisvol) • Activity 6 – Plate Boundaries with Food • Activity 7 – Magnetic Reversals • Activity 8 – Convection
