This second title of Mia's Big Adventure Collection software series teaches sciences to children between 6 and 10 years old. The game's 12 educational activities teach about plants and their parts; animals, their habitats, eating habits and classification; weather, clouds; the solar system; earth science; the human body and its systems; heat energy; properties of matter fossils; electricity and magnetism. This adventure begins with Mia wearing her mother's gorgeous new hat, without permission, while playing on the roof of her house. Without warning, a torrential downpour washes Mia down the drainpipe. She barely manages to avoid being swept into the sewer, but her mother's hat slips away. Down the sewer it goes, where a rat named Romaine and his wretched cousins find it. Mia must get the hat back from Romaine or she'll be in some kind of trouble. With help, Mia must find enough sparklies to trade for her mother's hat. But hurry--mother will be calling her home soon. The Mia adventure series integrates fun learning activities into a story-game of exploration. In each adventure, kids lead Mia throughout her house and garden to find articles needed to complete a mission. Along the way, they encounter challenging activities to test their abilities. Successful completion of each task results in a reward, bringing the companions one step closer to their goal. Kids learn about plants and animals, and the solar system.
