What ECs could I do?

<p>I want to go on to study particle physics, but I'm not sure what extra curricular activities to do for it. I'm currently doing some ECs which aren't related to physics, such as: DoE, violin, and volunteering. In middle school, I was in a science club, but there isn't one at my high school, and there's not much based around physics.</p>

<p>Would activities such as owning a physics-help website, helping high school kids with physics, be considered as an extra curricular activity? Or attending physics seminars or lectures? Those wouldn't really count for 'extra-curricular activities' per se, but would they count for something?</p>
