In his backyard, Sid is pretending to be "Super Sid!" To show us his super strength, he kicks a soccer ball really hard and it sails across the yard. But when he tries to kick it to a nearby tree with the same might, the ball once again sails across the yard. On a special trip to the Science Center, Sid and his friends investigate how using lots of force can make something move really far and really fast - just like kicking a soccer ball really hard!
