Does a teacher really expect a second grader to explain this on her own? To fully explain and demonstrate it you need to understand electron flow, what constitutes a complete circuit, the fact that current will flow through the bird's legs and body (parallel path), but will be very low due to the high resistance compared to the conductor, and the bird's sensitivity to current. Was this intended to be a student/parent/any other more knowledgable person project? Is today's second grade reading level up to understanding the research material she would need to read for this project?
