Hello there Jael!
If you just got scratch and don't know how anything works you can look through the basic support page @ http://info.scratch.mit.edu/Support
If you know how everything works then you can try looking at the sample projects that come included with the scratch program. If you want, you can modify those projects, then upload them to the site for everyone to see.
The forums are a good source of information when you need help with something so if you are having trouble with anything you can ask for help in the forums.
Have fun scratching
