*Parents' Choice Award: Gold Winner 2009* *National Parenting Publication Award (NAPPA): Honors 2011* Sid wants to know why things have to change. Why does his yellow banana turn brown? How come his shoes are shrinking? What made his ice pop melt and just how does Grandma know how to make a pancake that is not too squishy or burnt? Sid and his friends work together to discover the effects of time, temperature and the environment with the help of some revealing experiments and songs.
