Whether your child loves sports, music or science, there’s an event on tap that will peak his interest this weekend. Cool off at the Chelsea Piers Sky Rink as you watch a free amateur figure skating competition. Trade in your kid’s bike for a newly refurbished one and brush up on cycling skills at the Bike Bonanza. Make an instrument and play along at an interactive percussion concert. Jam at an outdoor concert to protest the 91st Street garbage dump. Enjoy a festival of puppets. Or take part in the World Science Fair through an exploration activity at Brooklyn Bridge park – sun gazing with NASA scientists and learning physics from an amusement park engineer as you ride the carousel sounds pretty cool to us!
