 Be curious. That's what the Boston Children's Museum wants kids to do this summer. Throughout July and August, the museum will be offering engagement and investigation opportunities to spark an enduring spirit of discovery and wonderment. They're dubbing it the Summer of Curiosity. There are various events planned, themed programs, activities, and a summer carnival to encourage museum visitors to explore their curious side. A journey into the 100-acre wood with Winnie the Pooh has also been extended through Labor Day.
