Friday Family Fun Nights at Paradise Valley Mall, tonight is Back to the Future! "Start your evening inside the mall with a balloon artist, free carousel rides and dinner in the food court. Then gather the family to enjoy a free outdoor movie at sunset on the West Lawn, located outside JC Penney. Bring your blankets and chairs and settle in for a relaxing night under the stars."
More free movies outside with the Waterdance Film Festival at Westgate city center. Tonight is Transformers.
Take the kiddos to the zoo for free! The Phoenix Zoo is waiving the children's day time admission through August 31! They open at 7 during the summer and have a couple of nice splash pads to keep cool :).
And there's always splash pads and pools. Phoenix has a great pool/splash pad combo at Pecos Park. Paradise Valley has a pool too, but frankly, the city of Phoenix has a terrible web page system so finding info on their stuff is no easy task!
