Students will be able to create and use models to correctly describe themovement of plate tectonic boundaries by performing the edible plate tectonicslab.2. Student will be able to correctly identify the landforms created by plateboundaries by performing the edible plate tectonics lab.3. Students will be able to accurately explain that the movement of Earth’s crustalplates causes both slow and rapid changes in Earth’s surface by reflecting on their labactivity.4. Students will be able to accurately explain the purpose, benefits, and limitations ofmodels in science by relating it to their lab experience.Prior Knowledge Needed by the StudentsStudents should already know the layers of the Earth.Background InformationThe Theory of Plate Tectonics states that the crust of the Earth is composed of 7 majorplates and numerous smaller plates. These plates move on the top of the hot uppermantle called the lithosphere. This theory also says that these plates are in motion,creating a variety of interactions at the plate boundaries. At convergent plateboundaries plates converge or move towards each other. At divergent plate boundariesplates will diverge or move away from each other. At transform boundaries plates willslide past each other in a lateral motion. Convergent boundaries create volcanoes,mountains, deep sea trenches, island arcs, and subduction zones. Divergentboundaries create rift valleys, mid ocean ridges, islands, and volcanoes. Transformboundaries create fault zones and earthquakes. Earth has 4 main layers: crust, mantel,outer core, and inner core. The outer layer is the crust. The crust is the upper part of thelithosphere. Also part of the lithosphere is the cooler, upper part of the mantle. TheEdible Plate Tectonicspage 3
Kimberly MillerPrinted on 12/2/15mantle layer is the layer below the crust and it is the largest layer. The mantle consistsof 3 layers: the outermost layer is the lithosphere, the middle is the asthenosphere, andthe inner layer closet to the outer core is the mesosphere. The outer core is made up ofmolten iron and nickel. The inner core is made of solid iron and nickel.Oregon State University. (2015) Earth’s Layers Lesson #1. Retrieved esson-1Oregon State University. (2015) How Earth’s Plates Move Lesson #3. Retrieved es-move-lesson-3Lesson ProcedureEngage1. Have students watch the ice age video clip.https://www.youtube.com/watch?v TzzGPfVx32M Make sure to fast forward past the advertisements and display the video“whole screen” so that the web page advertisements located on the bottomand sides will not be seen. In addition, please be on the lookout for pop-upads while the video is playing.2. After watching the video clip ask students the following questions: What did you observe from the video? Students’ responses may vary but could include that they observed thelayers of the Earth, the separation and movement of the continents, the“ball” at the center of the Earth, etc. How does this video relate to Earth’s layers? Students’ responses may vary but could include that they saw thesquirrel go through the different layers of the Earth, they saw thesquirrel land on the inner core, etc. What did you observe about what was happening to the crust in the video? Students’ responses may vary but could include that they saw itsplitting into pieces, they saw pieces moving apart, etc.3. Have students re-watch the video and ask them what other details did younotice? Students’ responses will vary.Explore1. Have students perform the lab (Blackline Master #1) to gain a better understandingof plate tectonic motion without introducing academic vocabulary such asconvergent boundary, divergent boundary, and transform boundary.Edible Plate Tectonicspage 4
Kimberly MillerPrinted on 12/2/15Explain1. After completing the lab, students will fill out the first two rows in their graphicorganizer (Blackline Master #2). Students will complete this graphic organizer by continuing to add informationthroughout the lesson.2. Upon finishing the lab and the first two rows of their graphic organizer, students willcomplete the “Additional Reflection Questions” in their lab packet.3. Possible questions for class discussion could include:a. What is responsible for creating the force that moves the Fruit Roll-Ups andgraham crackers? Convection currents in the mantle.b. How might the movement of tectonic plates help build up Earth’s crust? When plates collide, crust is pushed upward and mountains are built.When plates move apart, magma flows up to the surface of the Earthcreating new crust. Volcanic eruptions from plate motion allows lavato flow creating new crust.c. How might plate tectonics moving tear down Earth’s crust? When plates collide, sometimes crust is pushed downward(subducted) back into the mantle where it melts.4. Show students the attached landforms presentation slides. Ask students thefollowing questions when you get to the slide pertaining to the question. Studentswill then write the landforms on their graphic organizer in the appropriate area.a. Which movement from your plate tectonics boundary graphic organizercaused mountains to form? Converging continental plates (graham crackers moving toward eachother).b. Which movement from your plate tectonics boundary graphic organizerformed the mid-ocean ridge? Diverging oceanic plates (Fruit Roll-Ups moving away from oneanother).c. Which movement from your plate tectonics boundary graphic organizercauses a rift valley to form? Diverging continental plates (graham crackers moving away from oneanother).d. Which movement from your plate tectonics boundary graphic organizerwould cause fault lines? Transform continental plates (or oceanic plates) (graham crackers orFruit Roll-Ups sliding past each other).e. Which movement from your plate tectonics boundary graphic organizerwould cause trenches?Edible Plate Tectonicspage 5
Kimberly MillerPrinted on 12/2/15 Converging oceanic or oceanic and continental plates (grahamcracker and Fruit Roll-Up or two Fruit Roll-Ups moving toward oneanother) creating a subduction zone.f. Which movement from your plate tectonics boundary graphic organizerwould cause volcanoes? Converging oceanic or oceanic and continental plates (grahamcracker and Fruit Roll-Up or two Fruit Roll-Ups moving toward oneanother) creating a subduction zone. This results in volcanoesforming on land next to the subduction zone or island arcs to form inthe ocean.5. State the definition of convergent boundary and have kids match which parts of thelab correspond to this type of boundary. Have them fill out that row in their graphicorganizer.6. State the definition of divergent boundary and have kids match which parts of thelab correspond to this type of boundary. Have them fill out that row in their graphicorganizer.7. State the definition of transform boundary and have kids match which part of thelab corresponded to this type of boundary. Have them fill out that row in theirgraphic organizer.Expand1. In this part students will be divided into 3 different groups to do a type of jigsawactivity.2. The teacher can choose to print Blackline Master #3 on different colored paper orhave some other indicator separating groups. Each group/color corresponds to atype of tectonic boundary (convergent, divergent, transform).3. Give each group a different colored sheet of Blackline Master #3 on which towrite their responses (ex: pink papers are given to the groups researchingdivergent boundaries).4. Allow the students 10 minutes to research the landforms that are created by theirplate tectonic boundary type. Each student in the group must find a differentexample and the location in which this example is located (no repeats within thegroup).5. Have each student write their landform and those that are discovered by theirgroupmates on the colored paper in the appropriate column.6. After students have completed their research, have students stand up and walkaround the room while the teacher plays the rap video:https://www.youtube.com/watch?v dkELENdZukI Play only the AUDIO for the video at this time. Do not allow thestudents to watch the video, this is only meant to be used forbackground music.7. Every 30 seconds have students stop (also stop the music) and pair up with twoother people creating a group of 3 where each colored paper is represented.Edible Plate Tectonicspage 6
Kimberly MillerPrinted on 12/2/158. Have students write down the other students’ answers in the appropriate columnon their graphic organizer (Blackline Master #3).9. Allow students to move around and pair up a total of 6 times, allowing students achance to record 6 additional examples of boundaries on their paper.10. Have students go back to their graphic organizer (Blackline Master #2) and fill outthe landform row based on the information they collected in their Group-PairShare Activity (Blackline Master #3).11. (OPTIONAL) Lastly, you can have students share their examples and place themon a map. This part can be done either posting world maps on classroom wallsand mark examples with post it notes or colored stickers, projecting a world mapon the smartboard and marking examples with dots, using Google Maps droppins at example locations.a. Ask the students the following questions: What do you know notice about the placement of the dots? The dots should be around plate boundaries and follow a patternof the edges of plate boundaries. What conclusions could scientists make about where these landformsare located? The location of the landforms should be around plate boundariesand follow a pattern of the edges of plate boundaries.12. (OPTIONAL) Play the rap video and this time allow the students to see the video:https://www.youtube.com/watch?v dkELENdZukI Make sure to fast forward past the advertisements and display the video“whole screen” so that the web page advertisements located on the bottomand sides will not be seen.

Kimberly MillerPrinted on 12/2/15Additional Reflection Questions1.Why is what you did with the graham crackers, Fruit Roll-Ups, and frostingconsidered a “model” of plate tectonics?The graham crackers, Fruit Roll-Up, and frosting were representing other, real-life objects.We were simulating the plates and their different motions. This represented real-life.Because these are representations, they are considered models.2.Why do we use models in science?Sometimes it is too dangerous to study real-life objects. Sometimes they are too large(planets, solar system), sometimes too small (atoms, cells), sometimes too abstract(weather) to study in real-life. Models are good for showing how multiple parts interacttogether.3.Why was it beneficial (helpful) to use a model of the plates and the platemovement?The plates are too large and their motion too unpredictable to study directly. Also, somemovements happen really quickly and others very, very slowly to study directly. Modelsallow us to understand all the parts and how they fit together as a whole.4.What were some of the limitations of this model? In other words, what are somethings that this model cannot demonstrate about plate tectonics?The model cannot accurately demonstrate how the magma fro

The physical theory of plate tectonics thus has important applications to planetary habitability and the origins of life in the universe (e.g., Korenaga 2012). However, if we do not have a theory to explain why plate tectonics initiated on Earth and how it evolved with time, we cannot apply our understanding to other planets under
