How about a history project on the Mayflower? It is the ship that carried the Pilgrims to the New World. You would get to build a model ship, and you would need to put together display telling how the Mayflower helped the Pilgrims across the ocean.
You should do a presentation on Egyptian mummies! They are fascinating creatures (yes, I know they're dead) and have looong been one of the main attractions of the ancient world. Go for it. B-)
