Though it's low-voltage, a car battery can provide an enormous amount of current, often more than 200 amperes. If you drop a screwdriver across the terminals, for example, enough current will flow to vaporize the screwdriver and splatter molten metal all over the unfortunate mechanic.

A significant danger is that sparks resulting from a short will ignite free Hydrogen released by the chemical reaction inside the battery.

This really looks like a blatant effort to get us to do your homework. I do not think this is proper use of the forums. With a bit of effort on your part all of this information is available.
