Make a solar system necklace out of polymer clay to supplement an astronomy lesson. Create a bead for each astral body, including the sun, the eight major planets, one dwarf planet, and the asteroid belt. Make each planet out of a clay corresponding to the color it normally has in space. Use a toothpick to poke a hole through each bead for stringing. For the asteroid belt, create a circular loop out of clay. Bake all of the objects in a 200-degree oven for 10 minutes. Once they are cool, string them together to wear as a necklace.
Use a polymer clay volcano as a model when teaching geology. Place one pound of polymer clay onto a cookie sheet and form it into a mound, pushing the edges down around all of the sides. Pull the mound up into a point, then push the very center down to create a well. Pour four tablespoons of baking soda into the well. In a bowl, combine 1/4-cup vinegar and 10 drops of red food coloring. Pour the vinegar mixture into the well, and watch as the vinegar combines with the baking soda to create foam that looks like lava running down from a volcano.
Make a clay model of an earthquake to simulate the inside of the Earth's crust after an earthquake. Using three different colors, roll clay into a ball, then into a 1/2-inch thick sheet using a rolling pin. Layer the three sheets on top of each other, pressing them down gently. Use a knife to cut diagonally through the stack. Move one side of the stack slightly askew to represent how the Earth's crust shifts after an earthquake.
