Give each family or group a bag and an identical list of items to collect from nature (e.g. 5 flowers, 4 pebbles, 7 twigs, 10 leaves, 6 feathers, 2 pieces of bark) and once the items have been found, gather together at a table with some glue and paper and each team must create a 3D nature picture with just the items found.
Each team could make a picture which is a different part of the same Bible story and then put them all in a row when they are finished to see the full storyline.
