Sanjay was in the kitchen when his sister, Priya, ran by. She had a bundle of markers and several pieces of cardboard. The next time she went by, she had a Betsy doll and a Space Man figure. "That's my Space Man!" Sanjay said. "What are you doing, Priya?" He followed her into the family room. "I was watching videos on the Internet," Priya said. "I saw a film that a kid made and decided to make one myself."

Sanjay eyes lit up. "You'll need actors! Can I be in your movie?" Priya shook her head. "I don't need actors. This is going to be a stop - motion animation." "Animation?" Sanjay asked. "I'm going to take lots of pictures of Betsy and Space Man. I'll move them a little between each picture," Priya explained. "When I put all the pictures together, it will look like they're moving! Want to help?" asked Priya. "Sure." said Sanjay.

Sanjay helped Priya color buildings on a piece of cardboard. "This will be the background," Priya said. "Betsy is going to chase Space Man." "Why is she going to chase him?" Sanjay asked. Priya shrugged. Sanjay laughed. "Priya, she needs to have a reason for chasing him. If she doesn't, the film won't be interesting. Let's come up with a story with a beginning, middle, and end." Priya and Sanjay thought.

"Okay," Priya said. "Betsy puts down her favourite marker. When she isn't looking, it rolls away and Space Man finds it. He picks it up and - "Betsy thinks he stole the marker, " Sanjay added. "so she chases him!" Priya smiled. "Perfect! Then he falls down and she takes back the marker. The end!" Sanjay set up the cardboard background. He placed paper and a marker in front of Betsy. Priya got the camera ready.
