Which Senses Do Robins Use to Find Worms?
Article | Journal Page

Seeing, smelling, hearing, touching, and tasting. How would you set up experiments to investigate the sense(s) robins use to find earthworms?

Dr. Heppner’s Experiment Kit
  • Pieces of dead earthworm
  • Living earthworms
  • Rotten eggs
  • Decaying meat
  • Rancid butter
  • Mercaptoacetic acid (which smells like a cross between sewer gas, rotten cabbage, a skunk, and a stinkbug)
  • A small drill
  • A tape recorder that's extremely sensitive at low frequencies


How would you use the items in Dr. Heppner's Experiment Kit to test each of the robin's senses? Record your experiment ideas here.
