Oh no! Otis needs a science fair project in a hurry.The problem is that all the good ideas are already taken and the judges will arrive on Friday. Luckily a blue jay outside the classroom window inspires Otis to make a bird feeder and observe which birds come to it. Even when other kids question the "scientificness" of his project and no birds come to the feeder, Otis doesn't give up--wining the prize for stick-to-it-iveness.
