This penguin needs a haircut. Ada first graders are learning about penguins...and may know more about the tuxedo-dressed-looking bird than do most adults. How many eggs do they lay, what do they eat, who are their enemies? Ask a first graders, they’ll know. Their drawings of penguins are displayed on a wall at the Ada Schools. (Answers: 2; small fish and krill; orca whales and leopard seals.) (Monty Siekerman photos)
