Dora and Isa have been learning how the Earth’s natural energy can power things we use everyday. So they’ve made a volcano that rumbles, goes KA-BOOM, and lights up a pretend city for the Science Fair! Ooo. Maybe we’ll win the science trophy! C’mon, we’ve gotta get our volcano to the Science Fair quick! We’ll go on a science-filled adventure finding the metal pieces for Magnet Bridge; feeding the animals at Diego’s Animal Rescue Center (by finding out whether they’re carnivores or herbivores); and rush all the way to the Science Fair – just as the judges arrive!
