  1. Record your prediction for how long it will take for the worm to go under.
  2. When ready to being, put one earthworm on the surface of each bucket of soil.
  3. Time how long it takes for the worm to disappear below the soil's surface.
  4. Place the worms and soil safely outdoors to return to life as usual.
