http://pbskids.org/sid Did you know you can measure a classroom using a "paper body?" Watch and try this investigation, featured in the Sid the Science Kid episode "The Whale Episode." Not all things have to be measured using a traditional ruler. You can use your body as a "ruler" too!
Don't miss Sid the Science Kid, the new animated preschool series from The Jim Henson Company and KCET on PBS KIDS! (check local listings). For more information visit http://pbskids.org/sid
