M Is For Meteorite

S2, E34: While Robyn interviews Headmaster Crane for a blog story about how science is essentially mystery-solving using evidence and deduction, Coot rushes into the Zen Garden with news that a meteorite has landed somewhere on campus! He doesn't know exactly where, but his detection machines have never been wrong. An excited Robyn wants to find the meteorite, and she enlists Eagle, Hawk and Raven to help. Clues lead them on a path all over school grounds - even underwater, into the bay - till they finally deduce that the rock ricocheted off the Spacenasium's lightning rod... but then the clues run dry. Discouraged, Robyn decides to catch up on other projects, including her blog entry. Which is when she notices something in a picture she took of Crane earlier that day... a rock that wasn't there before, now jutting up from his reflection pond. Could it be...?!
