Purpose : Students learn the usage of programming (Motion, Looks, Basic events, Variables, Operators, Custom events etc.) and also develop their own project. Using simple sequences and loops to create animations.
Good knowledge about Sprites, Backdrops, Costumes, Variables, Operators, Conditional statements and Loops, events, sensing etc.. in scratch.
Exercises
Exercise:1
Identify a small video on the internet. Convert that into a gif and then to a series of costumes or backdrops. Add sprites and dialogues to make an animation movie with your own imagination.
Teachers should recall variables, operators, lists, broadcasts, etc.
Help the student to create the algorithm (Documentation) of the story. What will happen in what order? What will trigger what other actions? etc.
Teachers should teach how to make animations and the usage of GIF files in creating animations. Scratch will create costumes for all the frames when we upload the animated GIF files.
The teacher can encourage children to figure out by themselves how to save a video as a gif file (i.e. find out using Google search).
Explain how videos are just a series of frames or photos. By playing these photos in quick succession, it feels like a continuous motion. If the children have not used stick figure animations, you can show them this video. Videos as a series of photos use the same principle. You can show the following video to the students to help them understand this.
