Because the donations list is rather extensive and time is short, I'd like to suggest that you focus your collection on a few items. One of the best donation drives I've seen encouraged children to pick out a box of their favorite cereal to share with another child. It was very concrete and easy for children to understand. Something simple - a can of soup, a roll of paper towels, etc - may also be easier for busy parents.
Thank you for supporting this effort. If you have any questions, please do not hesitate to contact me.
