Science Buddies: "Ask an Expert"

Hi all,
I was wondering whether or not science fairs would allow me to explain my project by drawing pictures/diagrams on a white board of some sort. It'd be much easier to explain it that way, but if they don't allow it, then I'll have to find the right words to explain it.

Am I supposed to give an explanation of my project that flows from one topic to another, and THEN have the judges ask questions? How long are these presentations?

Also, how formally do people usually dress at science fairs? I know, it's a random question.

Thank you,
-M

Most of the answers to these questions vary from fair to fair. Each fair has its own rules and guidelines. The best way to answer your questions would be to talk to someone who is involved in the fair you will actually be participating in.

Dress for success. Guy: collared shirt and tie; Girl: skirt and blouse or business suit.

This is not specific to science fairs, but this web page has some good general advice about preparing and presenting a scientific poster:
