Tectonic plate projects are easy to make.
Tectonic plate projects can be designed easily by creating an interesting salt map from ingredients found in most kitchens. Salt maps can be used to create lithospheric plates and tectonic plate boundaries for 3-D projects, and they provide an excellent method for projecting the theory of plate tectonics.
Instructions
Prepare to Create Your Tectonic Plates
1. Lay all supplies needed for the project on sheets of newspaper placed on a table.
2. Sketch tectonic plates on cardboard using the marker. Tectonic plates are slabs of lithosphere, or upper crust, and do not overlap one another unless volcanoes and mountains are formed. Sketch your plates at varying distances from one another, and create some plates that are directly adjacent to one another.
3. Mix salt and flour in a bowl with a spoon.
4. Stir water into the mixture slowly with spoon until the solution is as thick as cake icing.
5. Separate the mixture into three bowls.
6. Add food coloring to each bowl's mixture. Add five to 10 drops of blue food coloring to one bowl, five to 10 drops of red food coloring to the second bowl and five to 10 drops of brown food coloring to the third bowl. The blue salt mixture will represent water between tectonic plates. The red salt mixture will represent magma filled cracks between tectonic plates, and the brown salt mixture will represent the tectonic plates.
Build Your Tectonic Plates
7. Apply brown salt mixture on top of the tectonic plates you sketched on cardboard. Apply the mixture with a spoon, and smooth it with a spatula.
8. Apply blue salt mixture between a few tectonic plates you mapped out to represent ocean. To apply the mixture, use the spatula.
9. Apply red salt mixture between the remaining spaces between tectonic plates to represent magma oozing from the lithosphere. Use the spatula.
10. Dry the salt map overnight in a cool, dry place.
11. Label tectonic plates on the dry salt map. With black poster paint and paintbrush, label the brown land masses "tectonic plate," the blue areas "ocean" and the red areas "magma." Write "Tectonic Plate Model" on the upper middle portion of the salt map.
