It's a very windy day on Sesame Street. Elmo and Telly are just about to play a game of basketball. When they return from eating a healthy power snack, their ball is missing! It's a real mystery and they need to investigate to solve the problem! First, Telly writes down what they already know about the mystery! Then, he forms a hypothesis, or a guess, that Abby must have made the basketball disappear because she's able to do magic. Abby tells them that she was with the seven dwarves so it couldn't have been her. Telly and Elmo investigate further and Elmo suggests that they look under the table. The basketball isn't there and now Telly's notebook and crayon have vanished making the mystery even more mysterious! Elmo discovers a new clue and after thinking about where he's heard this "whoosh" sound before, he forms a new hypothesis- the Big Bad Wolf did it! The Big Bad Wolf explains that it wasn't him either. Now they hear the "whoosh" again and Telly's hat is missing! This time they also feel a tickle but don't see anything. Leela comes by and helps them piece all the clues together. What can be all around that you can sometimes hear and feel, but can't see? Wind! Elmo and Telly experiment and test out their new hypothesis and see if the wind made their things disappear. They follow a leaf flying in the wind and find all of their missing things. Their hypothesis was right- the wind made the objects disappear! They solved the mystery! THEME: Science J / 17
