Giving a Presentation Tomorrow, any Tips?

[Drew S]

I was asked by a friend at work if I would stop by the school he volunteers at tomorrow and give a half hour presentation with some reptiles to around 20 kids.

It sounded like it could be fun. The only thing is, it has now turned into an hour long presentation...to 60 children and 40 adults. I'm planning on bringing the following:

Snakes:

Brazilian Rainbow Boa
Hogg Island Boa
Ball Pythons
California Kingsnakes

Lizards:

Frilled Dragons
Bearded Dragons
Veiled Chameleons
Panther Chameleons
Leopard Geckos
Satanic Leaftail Geckos

Turtles:

A couple huge red-eared sliders
Red Foot Tortoise

And maybe some hermit crabs.

I'm leaving all of my particularly agressive snakes at home, just incase.

I'm just going to give some facts about each species, where they're from, what they eat, how big they get etc.

Just wondering if anybody had any pointers for me? I've never done anything like this before to anyone outside of a few friends. hehe.

Thanks,
