The Big Question: "Why does my hair stick to my chair?" 1) MY GREAT CHALLENGE: Kids race to complete a circuit! But before they can do anything they must find a way to transfer power over a short distance, from a battery to a light bulb, by determining what materials conduct electricity. 2) IN THE FIELD: Harrison goes to the Sea Aquarium to visit a marine expert and some willing aquatic life to explore why electric eels don't electrocute themselves and how sharks can detect our presence because of electricity!.
