Sixth graders discover that Earth's surface is a set of giant moving plates, and that their slow collisions and separations build mountains, open oceans, and trigger earthquakes.
Students will be able to…
The ground feels solid and still, yet continents drift, oceans widen, and mountains rise. What is moving beneath our feet, and what does it build and break?
Project this and answer each question about Earth's moving plates and their boundaries — read the explanation after each one.
Tap any phase to open the teacher moves and student actions.
Earth's surface is cracked like an eggshell into huge pieces. What happens where they meet?
Students answer questions about plates and boundaries.
Students connect boundaries to landforms.
Students diagram one boundary.
Students reflect on plate motion over time.
Aligned to the Next Generation Science Standards (Grade 6 / Middle School Science).
Analyze and interpret data on the distribution of fossils and rocks to provide evidence of past plate motions.
Construct an explanation based on evidence for how geoscience processes have changed Earth's surface at varying scales.
Develop a model to describe the cycling of Earth's materials and the flow of energy that drives this process.
Integrate quantitative or technical information expressed in words with a version expressed in a diagram or map.
Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.
Have students pick one boundary type, draw the two plates, and show the direction of motion and the landform or event it produces. A printable plate-tectonics worksheet is in the Science library.
Tap a card to flip it, then rate whether you knew it. Built from this lesson’s vocabulary.
