S1, E12: If there's one thing Addie can count on, it's that she bites at Science Fair. Zach, on the other hand, is a Science Fair prodigy. Addie realizes that if she can get Zach to agree to be her partner, she might actually have a chance of winning. Or at least not failing miserably. Addie does everything she can to convince Zach to join forces with her, but Zach refuses. When the rift between Zach and Addie begins to threaten their friendship, they realize that perhaps there are more important things in the world than Science Fair.
