Prof. Smedley-Smythe holds a science contest for young people, who are to prepare any kind of scientific projects and present them to a jury. Bert's digging for dinosaur fossils, while Cedric and his father build a flight device resembling a pedal-driven helicopter.
After not too long, Bert finds a promising tar pit and prepares to examine it more closely. But the pigs, thinking they'd improve Cedric's chances in the contest by sabotaging Bert's project, sink a heap of fresh bones in the pit, and thus cause confusion as usual.
