Also, it is very important to incorporate scripture wherever possible and appropriate. The Bible contains many things that speak to science or focus on who God is as Creator. The children need things to do and look at while the leader or teacher explains some simple creation points. For older children, a chart of the geologic column could be included as a way to explain evolution as it relates to rocks and the age of the earth. Children can also dig in sand boxes for bones or plastic skeleton pieces while being taught about fossils and what paleontologists do.
Live animals are always winners with kids, and make great centers.
God's goodness and creativity are shown by how animals are so well suited to their particular way of life. Sometimes it is very effective to put children in pairs with an older child going with a younger child, teaching and helping them. It is very important to teach kids how to recognize creation and evolution terms and help them be able to recognize the differences between the two when they look at a book, for instance. One very good system is to use different colored stickers for books to help kids know the difference between a creation book and an evolution book. Children do not recognize that these mean evolution unless they are taught so.
