The girls create science projects for Experiment Friday. Jas transforms the art room into a spaceship to conduct an experiment into how teenage boys deal with being cooped up together on a long space voyage. Meanwhile, Lily and Martha have been paired with Cassie and Maxwell. Lily is fretting that she and Rob are obviously incompatible as he hates her favourite naturalist Steve Batchelor and Cassie and Maxwell decide to 'study' Lily as part of their science project, researching teen relationship issues.
