Okay. First, please keep all your questions in one thread because it will help us help you better. Second, this is a web forum, not a chat room--experts get on and check the forum at most once or twice per day, so you shouldn't expect an immediate response.
Here is a site about what a variable is from our website: http://www.sciencebuddies.org/mentoring/project_variables.shtml
. If that is too complicated, try clicking on the 'variables for beginners' link up near the top of that page. Once you've read those, post back here if you still have questions--but keep in mind that no one may be able to answer you before tomorrow.
I am not particularly good with titles either; I think 'Putty competition' is just fine. I would avoid using your name in the title, though.
What about 'Science isn't Silly (Putty)!' It's kind of, well, silly--but it is eye-catching.
