The 4 tactile surfaces will represent rock of various ages depending on how long ago it was laid down.
Picture of a sea floor spreading model activity cut out.
Cut out the labels approximately 1 tall by 1 2 wide.
Modeling sea floor spreading reviewing content mid ocean ridges are long underwater mountain chains that rise up from the ocean floors.
Students will make their own models of seafloor spreading and the magnetic strips that occur in the seafloor.
Students will make a paper model illustrating the concept of sea floor spreading and the development of symmetrical magnetic stripes on either side of a mid ocean spreading center.
A model of seafloor spreading purpose.
Place a piece of white paper on the cardboard and cut the paper so that flaps of paper can be pulled down.
The width and length of the base are not critical as long as they are at least 12 cm wide and 30 cm long.
This model represents the flow of lava over time due to plate tectonics at mid oceanic ridges seafloor spreading.
During sea floor spreading two tectonic plates move apart forming a crack in the ocean floor.
Model of seafloor spreading templates one with three straight lines and another with striped bands or striped bands with arrows colored pencils or crayons.
Have students work in groups of four.
Please refer to the picture as you build this model.
Seafloor spreading explore 1 subduction in trenches 1.
In this experiment you ll make a seafloor spreading model to learn more about how plate tectonics work and create mid ocean ridges.
Students work as individuals.
Continue pulling the magma strips until the magma sticks slide across the ocean floor and drop off into the trenches.
3 slits as shown here.
Cut out a piece of stiff cardboard eg.
New ocean crust is continually added to earth along these ridges in a process called sea floor spreading.
Cut slits in the cardboard each about 2 mm wide as shown eg.
A model of sea floor spreading teacher s guide ellen p.
Students work with a.
Have students pick up materials needed for the activity.
You can make your own model of a spreading oceanic ridge offset by transform faults as follows.
Cut 3 slits each slightly more than 8 cm wide.
Simple diagrams and easy to understand explanations of the processes are included.
The purpose of this activity is to make a simple model that shows the evolution of oceanic crust through sea floor spreading.
Today we are going to create a model that i hope will incorporate all of your important points 1.
To create a working model of sea floor spreading follow the model seen below figure 1.
As the ocean crust moves under the continental crust it creates a trench.
Print cut out and glue together a three dimensional paper model that illustrates sea floor spreading and subduction.
Over time new.
Plate tectonics tennis ball globe model activity print and color a two dimensional world globe showing plate boundaries then cut it out and.
The base is best if made from poster board or card stock.
