Bobby has to do a research project on fireworks, but doesn't know where to start.

      Bobby looks at the slip of paper with his topic, “Invention of Fireworks.”  He has no idea where to start.  He is supposed to fill out some “KWHL Chart” but his mind just isn’t working.  His brain starts to hurt as a hundred thoughts whirl through his head.  Fireworks?  Do they blow up or burn?  How long ago were they created?  How long do I have to do this project?  Isn’t gunpowder related to this? How is he supposed to complete this huge project?
