What are some songs I could sing for a Middle School Talent Show?

I'm trying out for my school's talent show and I have no idea what I should sing. My voice is ranges from Soprano 1 to Tenor 1 and I'm obviously a girl. When I get into higher notes my voice changes to an operatic tone and i have a very powerful, LOUD voice. I don't really want names of bands, I want specific songs. Oh! And, don't forget, it has to be middle school appropriate.
