Sid wonders what he could possibly do on his day off from school. But when all his friends come over for a play date, they quickly put their science minds together and decide to put on a show in the backyard! They each take turns rocking out as they sing their favorite science songs for a very appreciative audience of Mom, Dad, and Zeke! #PBSKIDS #SidTheScienceKid #SingAlong Watch and play more videos and games at pbskids.org or download the *FREE* PBS KIDS Video and Games app at pbskids.org/apps/
