I usually work with teenagers, so I took a childhood idea, and made it a little more difficult for the older kids.
This took a lot of preparation, and you will need a concordance.
I gave each teen a scripture to start with. They had to read the scripture and find a hint in the scripture as to where the next egg would be, which would contain the next scripture, etc. I used places inside and outside the church. The concordance will help find a scipture to use for whatever may be around your church. I also put a piece of candy in some of the eggs, along with the scripture.
The hard part was giving each kid a different starting place. I listed all the scriptures several times on a piece of paper, and moved down one line with each new starting scripture. So they were all in the same order, but one group was behind another in the search. It helped keep them from getting bunched up. I had them all end together though, which just takes a little thinking about where to send them last. Each church can customize this. I used one color egg for each group. That way they didn’t get someone else’s message. And we knew who had skipped an egg by what was left around. Most of the kids really enjoyed this. Hope yours does too.
