It's a bit late for this, but I have seen so many great ideas for celebrating Resurrection Day that I wanted to be sure to post some of them.
I love the Names of Jesus Garland at The Homespun Heart. Hat tip to Keeper of the Home for the link. I adapted this to use as a children's ministry craft. You can read about that here if you are interested.
Holy Experience shares instructions for making an Easter Garden. Although we should have had this ready for Palm Sunday according to the directions, we're making one today or tomorrow (haven't found plants yet) because it is such a beautiful and visual way of "remembering of the grief of old beginning, the dazzling wondering of new beginnings." If you haven't visited this blog before, be sure to stop by just for a taste of the writing!
Make your own Resurrection Eggs. I use these in our children's ministry every year. We hide them and everyone takes turns opening his/her egg, sharing the contents and reading the Scripture. It is a fun, interactive way to share the Scriptures relating to Jesus' death and resurrection.
We have also made Resurrection Rolls before. We make these on Saturday evening, but we leave them in the oven overnight, "sealing" it with tape. We "unseal" the oven in the morning and pull out the rolls after I have warmed the rolls up a bit. The first time we made them, the kids couldn't believe that the "tombs" were empty the next day! We are going to try making our own marshmallows for this instead of buying them.
The Archaeological Study Bible's Easter Story Site includes notes, images and information about several historical aspects of the Resurrection.

Hold That Thought offers printable Easter-related Scriptures and quotes to make into a Scripture card ring. They also provide instructions and a template for children to make their own Story of Easter, scrapbook style.
