A landform model can be shaped from simple, inexpensive dough. A range of geological features can be realistically modeled in this way, including mesas, canyons, volcanoes, plateaus, flood plains, mountain ranges, seashores, glaciers and rivers.
Before starting to make the landform, a stiff cardboard base of an adequate size will be needed to hold it. Around 9 square inches is sufficient for following this guide.
Step 1: Make the dough
Heat and combine 1 cup of plain flour, 1/2 teaspoon of salt, 2 teaspoons of cream of tartar, 1 teaspoon of vegetable oil and 1 cup of water in a saucepan, adding Earth-tone food coloring, if desired.
Step 2: Knead the dough
Once the dough stiffens, knead it for around three minutes to make it pliable.
Step 3: Shape the landform
Working from research and images, shape the chosen landform with the hands, keeping in mind the dynamic nature of the Earth and the crucial differences between landforms in the same category, such as between old mountains, middle-aged mountains and new.
Step 4: Allow to dry
The dough will usually dry and harden if left overnight; however, it might take longer.
Step 5: Display the landform
Paint the hardened feature and, if it is to be part of a larger display, perhaps make a sign to describe it.
