I believe the donation to the Scholarship fund will go towards seating in the link I provided earlier. The seat donations are anywhere from $50 to $500 per seat on the sides of Kinnick and no donation required for endzone seats.
Here is a list of the level of memberships and donation requirements. I believe season ticket sales for new members go like this:
Day 1: Kinnick Society and Champion Hawks
Day 2: the above and Golden Hawks
Day 3: all the above and Silver Hawks
Day 4: all the above and Bronze Hawks
Day 5: all the above and Century Hawks
Day 6: all the above and now the general public.
I-Club Membership Levels - The University of Iowa Foundation
So if you donate $50 to the scholarship fund you would order tickets on day 5 and that $50 would go towards a seat in a section on the side of Kinnick, however if you get 2 or more tickets each seat will require the $50 donation or higher depending on the seats you want and are available.
