Summer Science Programs in Massachusetts?

<p>Thanks so much for the program list! I just had a question about emailing professors/departements. Is it customary for high school students to do this? I’d love to do this, but I’m just not quite sure how to go about it. Is it really as simple as asking if they have any openings for high schools students and that’s it? If they do, would it be rude to turn it down (in the case that I’m accepted at some other program)? I’m assuming I would be doing some little jobs and errands here and there, so I don’t know if I should take this route or opt for something that would allow for a bit more education. Do you think it’s possible to do these sorts of internships not just during the summer, but during the course of the school year as well? Thanks, by the way; this helps a lot!</p>
