It's evening at the cul-de-sac, and the kids are looking at two asteroids through Sean's telescope - one is light-colored and one is dark. Meanwhile, Mitchell's dog Cody seems to have run away because he doesn't like the black sweater Mitchell put on him. The kids learn about how, just like asteroids, some things are easier to see in the dark than others, like a white card is easier to see than Cody's black sweater. This amount of brightness is called "albedo." The kids go to their local beach to surf, but notice that the beach looks completely different from the last time they stood there. There's way more sand, and the ocean is far away! They decide to be detectives and study what has happened, and learn that the larger and smaller beach is caused by the tides - the rising and falling of the ocean.

ARTHUR is based on the best-selling children's books by Marc Brown. The series revolves around an eight year-old aardvark, his four year-old sister DW, and their family and friends. ARTHUR is a show about being a kid, exploring the world, and finding your place in it. It's about kids finding inner strengths, learning to make choices for themselves, taking responsibility for them and of course, having fun. In each episode, Arthur and his gang guide us through stories that deal with real "kid issues" -- timeless difficulties and joys that all kids experience. The series also models the joys and rewards of literacy by presenting the many ways kids and adults incorporate reading and writing into their lives. Above all, ARTHUR is a comedy that tells its stories from a kids' point of view, never moralizing or talking down to them.

Kids in glamorous Gollywood have no safe place to play. When they discover an empty lot that can be converted to a park, they have only one opponent: Hacker. He wants the lot for his new Gollywood Tower, which he claims will broadcast entertainment to all of Cyberspace. (The tower is really meant to corrupt Motherboard's hard drive.) The CyberSquad goes up against Hacker at a city council hearing. Will they get their park, or will Hacker dazzle the council into approving his tower? Big idea: Communities need to provide safe, inviting outdoor spaces where kids can play and be physically active. Math concepts: Data Collection and Representation: Surveys, Tally Marks.

Creech invites her good friends the CyberSquad to Tikiville to show off the amazing new bike path that has everyone driving their fantastic new bikes and trikes rather than cars. Everyone is having fun - even Hacker is joyriding on his bike (and if that isn't suspicious, Jackie doesn't know what is). Inez, who cares deeply for animals, soon realizes the bike path has divided the habitats of many of Tikiville's cute, cuddly creatures. Creature families have been split up, and the busy bike path is preventing animals from reaching their food and water sources. Inez feels the bike path should be shut down, but Creech doesn't want to take away the benefits the path has created for her community. The disagreement drives a wedge between the two good friends. Will they find a compromise? Will a map of the area help Inez and her friends reunite the cute critters to their families and homes? And what is that sneaky Hacker up to?!
