|| Join Sid the Science Kid as he explores, investigates, and discovers in this bundle of three stories! When Sid the Science Kid finds rolie polies in the yard, he wonders how these bugs move around. They're too small for him to see how. He explores how other animals move to see if rolie polies move the same way. Snakes slide from side to side and fish use their fins, but how do rolie polies move? Do you know? In "Hello Doggie" Sid wonders whether animals talk. They don't use words like people do, but listen...are they saying something? What do you think a dog is trying to say when he barks? Does he want something? Or when a cat purrs? Is she trying to tell you she is happy? And in "Re-used Robot" Sid's favorite toy robot, Flip, has broken! He tries to fix Flip but can't, so he throws him away. What will happen to Flip once he's in the trash? And what happens to all our trash? Is there a way to reuse trash by turning into something new? Read along as Sid explores all these things!
