Surrounded as we are by so many tech start-ups, a world-class science museum, and some of the top college computer-science departments in the country, it's no surprise that many of our kids are fascinated by all things STEM (Science, Technology, Engineering, and Math). Luckily, a growing number of tech-minded summer camps are cropping up all over the region to meet demand, and the options for local kids range from a program for wannabe inventors to a science immersion program just for girls. We’ve rounded up a dozen great school vacation programs where kids can tinker, make, build, code, invent, and experiment. Read on to find one that’s a good fit for your sci-tech lover, and sign up soon—early-bird specials are widely available this month, and some of these camps fill up fast.
