Does water boil past 100 degrees?

I'm trying to explain for science why the temperature of the water didn't rise when the water was boiling. Even after 5 minutes, the water still stayed at 98-100 degrees. I'm trying to explain where all this energy is going and I say because all the energy is now trying to convert the water into steam. Plus I'm pretty sure in normal atmospheric pressure the water just won't boil past 100 degrees. But I'm having trouble explaining this as you can see. Can you try and explain this more? I mean in school we are learning about the Three States of Matter and the Particle Theory and i have to write a prac report.
