Any recommendation for how to explain EA funds grants to friend?

I have a friend who is casually engaged with EA. They went on https://​​funds.effectivealtruism.org/​​grants and was browsing some of the grants and asking me about them. I get the impression this was well-intentioned curiosity, but I was at a loss to explain the dollar amount of some of the grants my friend pointed out to me, in light of the short “project description” provided.

The last thing I want to do in this post is call anyone out—I’m sure the rationale behind these grants was sound, and there is relevant information missing from the provided description—but I was surprised to find out that there are grants for university group organizing in the five and six figures, and some of these are not even for an entire year. I do think this is something that will (perhaps justifiably) raise eyebrows for the average person, if they are just learning about EA as a movement very focused on cost effectiveness, and haven’t yet internalized some of the expected value calculations that probably went into these grants. But also, in a couple cases, I personally am having a hard time imagining how these numbers make sense.

If you are reading this post and willing to comment—could you (1) help me make sense of these grants first for myself and (2) provide any pointers on how to explain them to someone who isn’t yet totally onboard with EA? I don’t want to indicate specific grants, but specifically, what e.g. is the argument for a 5 or 6 figure grant for one semester of university organizing at a specific school? I don’t understand how so much money could be needed. As far as I’m aware, most organizers are volunteers (but maybe that is changing?). Happy to take this to a private conversation if that would be more appropriate.
