Put 10k in your "long-term" bucket (at least two years). Since it's grant money that you'll need, I'd suggest nothing more risky than CDs. That way, the money is insured and no one could argue that you used in any way that could have lost money.

Park the rest (or all of it) in Ally bank and reap ~1% interest on it.

Anything else is too risky (especially right now in the current climate) and too short-term to do anything with.
