The Sample Projects Library is a collection of eight pre-made ScratchJr projects that use a range of blocks and features to show you the variety of projects you can make with ScratchJr. You can run these projects to see how they work, and you can change the blocks around to see what effect it has on the action.
Access the Sample Projects library from the Home screen by tapping on the question mark.
To run the Sample Projects choose a project and then tap on the Green Flag in each one. You can have a look at the scripts of the various characters, and even try changing the scripts to see what effect it has. The things you can’t do in a Sample Project are: add characters or pages, change the background, add a title, or save any changes that you make.
After you have explored the sample projects, tap on the home button to create your own project using the full ScratchJr interface.
