To make a salt map, a person should trace the outline of a country on a sheet of cardboard, make land formations out of self-hardening dough and then paint them when dry. The dough is made from flour, salt, water and cream of tartar.
Salt dough maps are great for teaching students about land formations in different countries. The first step is to decide on a country or continent to represent on the map, such as Africa, North America, Mexico or Great Britain. Next, draw the map onto a sturdy piece of cardboard. Many map outlines can be found online, making it easy to cut a template to trace.
Once the map is on the cardboard, make the dough by simply mixing together 4 cups of flour, 2 cups of salt, 2 cups of water and 2 tablespoons of cream of tartar. Next, press the dough flat to fill in and conform to the outline of the country or continent.
The next step is to create the landforms and elevations. Look online for a diagram showing the different elevation levels and then use the salt dough to form them on the map. After creating all the landforms, allow the map to air dry. Depending on humidity and the amount of dough, it may take up to 2 days. Then design a map key with different colors representing different elevations and paint the elevations according to the key to complete the map.
