Two teams touch down at the STARS space station to take on three scientific challenges to win out-of-this-world prizes. First, they must use their knowledge of forces by pumping air into balloons attached to rockets to land them on a target. Then, the young scientists dig for dinosaur parts in ball pits. Finally, a player from each team must memorise a pattern of animals on the Memory Path before guiding their partner across it. Meanwhile, Sam and Ayo must keep the lab at a cold temperature so they can conduct an experiment with ice. But can they work out how to keep themselves warm at the same time?
