Purpose
During this experiment, you will explore tectonic plate boundaries
across the globe. You will look at the formations that are found at
different kinds of plate boundaries, and see real-life examples of
convergent, divergent, and transform boundaries. From exploring
these boundaries across the world, you will see how oceanic and
continental plates react differently, even at the same kinds of
plate boundaries. With your group, you will focus on one plate
boundary and construct a model that helps the class to better
understand that type of plate boundary.
Materials (for each station)
 Internet access
 Projector
 Blank sheets of paper
 Writing utensils
 Modeling clay – brown, red, and blue
Procedure
1. With the class, briefly explore the interactive plate tectonics
map online (http://geology.com/plate-tectonics.shtml)
2. Select a plate boundary that your group will explore in more
detail.

3. With the class, look at the plate boundaries that will be
explored. Pay close attention when your plate boundary is
zoomed in on. Take note of the type of plate boundary it is and
what you see at the boundary – Lab Questions.
4. After all six boundaries have been looked at on the map,
discuss with your group your plate boundary. What type of
boundary is it? What formation is at the boundary? Are the
plates continental or oceanic?
5. Have at least two people from the group work with others in the
group to draw a picture of the plate boundary. The pictures
should include the mantle, the plates, and water if either of the
plates are oceanic crust.
6. Once drawings are finished, compare them to each other.
Discuss any differences and agree upon what is happening at
the boundary. It is important that the whole group comes to a
conclusion since you will work together to create one model to
share with the class.
7. Use modeling clay to build a model of the plate boundary. Use
brown modeling clay to represent the crust, red for the mantle,
and blue for water. Your model must include the mantle and
crust, but not all plate boundaries will include water. In your
models, remember that the Earth’s crust floats on top of the
mantle, and is also much thinner than the mantle.
8. Prepare with your group to present your model to the class.
9. Share your model with the class.

TEACHER NOTES
Before the lesson begins, have the page http://geology.com/plate-tectonics.shtml
up on the projector and ready to use.
Students should be split into six groups, since there are six different boundaries the
class will explore.
During step one, zoom into one or two of the flagged plate boundaries on the map that
students will not explore further and briefly talk about them with the class. The most
important things to make sure they understand at this point are the topographic map
and what is shows.
Plate boundaries that students will explore include:
Himalayas (convergent, continental continental)
Andes (convergent, continental oceanic)
Aleutian Islands (convergent, oceanic oceanic)
East African Rift Valley (divergent, continental continental)
Mid Atlantic Ridge (divergent, oceanic oceanic)
San Andreas Fault (transform, continental)
Groups can be assigned these plate boundaries in any way you think best, whether it be
by picking from a hat or assigning them before the lesson begins.
If it is possible, students will likely benefit from having time to research their plate
boundary more online. If there is the time and capability for them to do this, one day
can be spent researching the plate boundaries and the next drawing and building the
models.
You may want to model drawing plate boundaries or creating a model with clay for your
students; it depends on the kind of support you think you’re class will need to be
successful. It can be just as helpful to provide support to groups as they work.

Answer Key
Answers to Lab Questions
1. What type of plate boundary is your group exploring? (convergent, divergent,
transform)
answers will vary
2. What types of crust are interacting at your plate boundary? (oceanic, continental)
answers will vary
3. What can be found on Earth’s surface at your plate boundary?
answers will vary
4. Do all convergent boundaries look the same? Divergent? (Watching your
classmates presentations will help you answer this.) Why or why not?
No, not all convergent and divergent boundaries look the same.
Convergent boundaries can create mountains, volcanoes, or islands
depending on the type of crust that is converging. Divergent boundaries
can create mid-ocean ridges in the ocean or deep rift valleys on land.
