The Great Science Fair Disaster — Martyn Godfrey

The science fair just exploded!

"My father walked into my seventh-grade classroom, looked around, and smiled. Oh, no, I thought. He's going to do it again."

"My father" is Mr. Wilder, Marcie Wilder's father, who is also principal of her school. "It" is his newest great idea: the First Annual Fifth Street School Science Fair.

The "Oh, no"?

Well, Marcie's father's projects always turn into disasters.

But this project is going to be different. And it is....

It's a MEGA-disaster -- with Marcie in the middle!
