Display or distribute the image in the student chapter Aladdin Frame. (You can also download it for distribution from Google Drive.) Ask them what they think it is.

After students have made a few suggestions,  explain that this is an image of one frame of film. Each frame is one picture that the camera shot: when you show many frames one after the other, it looks like things are moving.

• If you have already completed the Flipbook Animation activity in the Introduction to Stop-Motion Animation lesson, remind students of how their flipbooks made it look like things were moving. Each card in a flipbook is like one frame of film.

Explain that even though most modern cameras don’t use film anymore, they still record the same number of frames per second.

Ask students: How many frames do they think there are in a second of film?

• After students have made a few guesses, tell them that there are usually twenty-four frames per second.

Now tell students that in the early days of movies, it wasn’t possible to film in colour. That meant that early colour films had to be coloured by hand. Movies in those days had – somebody had to paint colour on every single frame. The image in the Aladdin Frame chapter is from a silent movie that was colourized this way.
