One batch makes enough for two to four children to complete Activity 5, Worlds in Comparison.
- Large mixing bowl
- Waxed paper or parchment paper
- Two measuring cups (for dry and wet ingredients)
- A tablespoon
- Mixing spoons
- Food coloring
- Gallon-size sealable plastic bags or plastic containers
Mix 3 cups of water, 3 tablespoons of vegetable oil, 3 cups of salt, and 6 cups of flour.
Divide mixed ingredients into two, three, or four equal portions. Give individual children a portion to mix in a few drops of food coloring and knead on a sheet of waxed or parchment paper. To minimize food coloring mess, poke a hole in the dough for the food coloring and cover it with plain dough before kneading in the color. Add flour if the modeling dough is too sticky.
Store the modeling dough at room temperature in sealed bags or containers.
