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 Junior Einstein, and sign up soon—early-bird specials are widely available this month, and some of these camps fill up fast. And if your kids are itching for some STEM fun in the meantime, check out these brain-building boredom busters especially suited to cooler weather.
