Fun art project with the kids! Easy abstract painting that anyone can do! Just blob the paint on the canvas in random spots and blend! (would be interesting how students could make different pictures w/ the same colors and same blob positions)
Have a letter writing station where parents and siblings can write a letter to their loved one about how much they miss them and what has changed over the year that they have been gone. Attach it to the balloon for the balloon for the balloon release.
