Materials:

  • Air Dry Clay
  • Wax Paper
  • Circle Cookie Cutter or Mason Jar Lid
  • toothpicks
  • metallic gold spray paint (parent supervision)
  • ribbon
  • small plastic knife
  • newspaper

Instructions:

  1. Flatten out soft clay.
  2. Use Cookie Cutter or Mason Jar Lid to make a circular shape into the clay.
  3. Use plastic knife to cut a rectangle big enough for the ribbon to slide through. This needs to be a quarter of an inch near one edge of the circle.
  4. Use toothpicks to draw and create a design onto the clay.
  5. Let clay dry.
  6. Once dry, use metallic gold spray paint to paint your clay. May need to do two coats. Make sure to do this outside on top of newspaper. Also make sure to have parent supervision.
  7. Let paint dry. Finally, string ribbon through your medal where you cut out the rectangle. Tie the ribbon off and wear it proudly around your neck.

How it Works:

Some solids, like clay start off malleable are easy to bend because they contain water. However, when that water evaporates out because of heat, it hardens and is no longer malleable.

Extra Experiments:

  1. Try using clay that you find outside in the dirt. Does it work the same way that air dry clay works? Better? Worse? The same? Why do you think that is?
  2. Try cutting out different shapes in the clay like triangles, squares, rectangles, etc. Which shape holds the best? Which shapes seem to break apart easier? Why could that be?
