Codebreaking

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 work out if an object is heavier or lighter than another before placing it on a giant set of scales. Then, there’s a fast-paced game based on personal hygiene, where the young scientists must race against the clock to brush as much food as possible off giant teeth. Finally, the teams dress as bees with sticky legs to transfer pollen between giant flowers.

Plus, it’s Sam’s birthday, and Ayo has given him a coded message made up of strange symbols. Can he crack the code to reveal a big surprise?
