In his backyard, Sid is intently observing squirrels and really wants to know why they make funny squeaking sounds. It makes him wonder what kind of scientist investigates animals? Fortunately for Sid, today his class is going on a field trip to the Science Center, where a special guest greets them-it's Gabriela's Mom, Dr. Rosalinda Cordova! She is a marine biologist, and tells the kids about her exciting job SCUBA diving with whales. Completely enthralled, Sid wants to know if scientists investigate other kinds of animals too? Dr. Cordova uses a video connection so we can meet a real wildlife biologist studying pandas at the San Diego Zoo! This leads the rest of the kids to ask about science fields they're interested in. We meet a robotics engineer working on a 20-foot tall robot at the Jet Propulsion Laboratory, a chemist investigating stretchy ice cream in a kitchen lab, and a marine biologist at The Scripps Institute helping to keep the oceans healthy.
