When Sid sees a big truck come to pick up his family's recycling, he wonders why we have to sort out our trash. Teacher Susie explains to Sid and his friends that that the reason we sort out our trash is so that new, useful things can be made out of our old plastic, metal, glass and paper.

When Sid feels like the pancake that Zeke got at breakfast is bigger than his pancake, Mom and Dad explain that things aren't always what they appear to be. To illustrate their point, Mom and Dad show Sid lots of optical illusions where things look like one thing, then turn into another.
