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.
