Do I need to file a tax return?

I'm a college student and still considered a dependent under my parents name. However, I received a form in the mail regarding how much I received for tuition, scholarships and such. I also received a form telling me how much "taxable interest" i aculated in my bank account over 2008. Its only about 15 dollars. I don't know exactly what to do. Do I give this information to my parents?
