Adoration is an activity that basically teaches kids that worshiping is not always just singing. You have, perhaps a small group of kids. All you need is a chalkboard or a white board and one writing utensil. Play quiet music for approx. 15min. and pass the pen to one person. That person can then approach the board and write one or two words that he/she is thankful for (forgiveness). Then the student passes the pen to anyone in the room, and so on until each person has finished their own public adoration. After each student has finished allow the group as a whole to reflect upon what has been written. This way you can give your praises to God by meditating and thanking Him for what He has done.
