"Sid the Science Kid" uses comedy to celebrate children's natural curiosity about science and explores their "Why?" questions in everyday life. It features the energetic and inquisitive five-year-old Sid, who tackles the ideas that preschoolers find fascinating (Why do bananas go "bad"? How does my juice box straw work? How does a bird fly without a plane?). In each episode, viewers meet Sid's friends and family who help him find the answers to these questions.
